QRコードはどうやって作りますか？

QRコードを作るには、コードにさせたい動作を選び、QRコード作成ツールに情報を入力します。選択肢があれば静的または動的を選び、必要に応じてデザインを調整し、画像をダウンロードして、印刷・公開前にスキャンテストを行います。

これは7段階のQR作成フローです。種類の選択、ペイロードの入力、静的・動的の選択、カスタマイズ、ダウンロード、テスト、展開の順に進みます。ペイロードとは、URL、WiFiのログイン情報、連絡先、文書リンクなど、QRパターンが実際に保持するデータです。

  1. 1 目的の動作に合うQRタイプを選びます。
  2. 2 URL、WiFi情報、連絡先などのペイロードを入力して確認します。
  3. 3 固定内容には静的、編集可能なリンクや分析には動的を選びます。
  4. 4 読み取りやすさを保てる場合だけ色やロゴを調整します。
  5. 5 デジタル用途はPNG、拡大印刷はSVGでダウンロードします。
  6. 6 実際のサイズで複数のスマートフォンから最終ファイルを読み取ります。
  7. 7 リンク先と読み取り動作を確認してから公開・印刷します。

What Will You Need Before You Create a QR Code?

You need the content to encode, a web browser with internet access, and a clear idea of where the QR code will appear. An account is optional for many static codes but useful for dynamic codes with editable destinations and scan analytics.
  • Your finished content: a complete URL, WiFi network name and password, contact details, or a hosted file link.
  • A modern browser on a phone, tablet, or computer; no dedicated QR-making app is required.
  • The intended placement, such as a screen, flyer, menu, package, poster, or business card.
  • A decision about whether the destination must remain permanent or may need to change after printing.
  • Brand assets such as an approved logo or color palette if you plan to customize the design.
  • At least two test devices, ideally an iPhone and an Android phone, before a large print run.

How Do You Choose the Right QR Code Type?

Match the QR type to your goal: use URL for a website, WiFi for guest network access, vCard for contact saving, PDF for documents or menus, and link list for several destinations. If you are unsure, begin with a URL QR code or review the full QR type guide.

The QR Creation Decision Tree starts with the action a person should complete after scanning. Choose the payload type first, then decide whether the destination must be editable, choose an export format, and finish with a real-device scan test.

Share a website or landing page?

Choose a URL QR code. It opens a web address in the scanner's browser and works for event registration, campaign pages, social profiles, forms, and general links.

Create a URL QR code

Connect guests to WiFi?

Choose a WiFi QR code. It stores the network name, security type, and password so a compatible device can offer to join without manual typing.

Offer several links from one scan?

Choose a link-list QR code. The scan opens a mobile page containing your selected destinations instead of forcing one permanent endpoint.

Create a multi-link QR code

Collect feedback or RSVPs?

Use a URL QR code that opens your Google Form. Verify the form's sharing permission and test it while signed out before publishing.

Create a QR code for Google Forms

Need payment or donation access?

Use a URL or supported payment QR type linked to a destination you control. For public campaigns, show the organization name beside the code so scanners know what to expect.

Static vs Dynamic QR Codes — Which Should You Choose?

Choose a static QR code for permanent content you will never need to change after printing. Choose a dynamic QR code if you may update the destination or need scan analytics; it uses a redirect layer so the printed pattern stays the same while the final URL changes.
FeatureStatic QR codeDynamic QR code
How it works The destination or data is encoded directly in the QR pattern. A short redirect URL is encoded, then forwards scanners to the current destination.
Editable after printing No. Changing the payload requires a new code and usually a reprint. Yes, while the dynamic service and account remain active.
Scan analytics Not provided by the QR pattern itself. Available when the platform records aggregate scan events.
Best for Permanent contact data, stable WiFi credentials, and fixed one-time links. Campaigns, events, menus, documents, and destinations likely to change.
QR-Build access Free options are available for common types. Paid features may apply; verify current plans before publishing.

A dynamic QR code connects a redirect layer to an editable URL and scan analytics, which can support campaign measurement. It also depends on the provider and account remaining active, so verify current service terms before committing a long-lived print asset.

最も速い方法は、オンライン作成ツールを開き、適切なQRタイプを選び、内容を入力・確認して静的または動的を指定し、PNGかSVGをダウンロードすることです。一般的なQRコードなら2分以内で作成できます。

QRコードを作る7つの手順

  1. ステップ1 — QRコードの種類を選ぶ: 読み取り後に実行してほしい動作から考えます。WebサイトはURL、ネットワーク接続はWiFi、連絡先保存はvCard、公開文書はPDFなど、ペイロードに合う種類を選びます。

  2. ステップ2 — 内容を入力して確認する: 完全なURL、WiFi認証情報、連絡先項目、ファイルリンクを作成ツールに貼り付けます。静的QRは印刷後に修正できないため、リンクを別途開き、表記と共有権限を確認します。

  3. ステップ3 — 静的か動的を選ぶ: データが変わらず追跡不要なら静的を選びます。後からリンク先を変更する可能性がある場合や、管理されたリダイレクト経由のスキャン分析が必要なら動的を選びます。

  4. ステップ4 — デザインを慎重に調整する: 明るい背景に対して暗いモジュールが明瞭な場合だけ、枠、ブランドカラー、ロゴを追加します。パターン周囲の余白を保ち、ロゴを重ねる場合は十分な誤り訂正を使用します。

  5. ステップ5 — 適切なファイルをダウンロードする: Webサイト、メール、小さなデジタル表示にはPNGを使用します。看板や印刷には、拡大しても輪郭が鮮明なSVGを使用し、文書ワークフロー内ではPDFを使用します。

  6. ステップ6 — 配置前にテストする: 想定するサイズと距離で、iPhoneとAndroidのカメラからファイルを読み取ります。リンク先、コントラスト、余白、読み込み体験を確認します。

  7. ステップ7 — 公開または印刷する: テスト済みコードをメニュー、チラシ、カード、パッケージ、ポスター、資料、画面に配置します。「メニューをスキャン」のような明確な案内を添え、編集可能な元ファイルも保管します。

このガイドは実際の利用手順を扱います。ISO/IEC 18004に基づくデータモード、誤り訂正コード語、マスク、モジュールの選択方法は対象外です。

Which Common QR Code Types Should You Compare?

URL, WiFi, vCard, PDF, email, and link-list QR codes solve different tasks. Select the type that matches the payload, then use dynamic delivery only when editing or analytics justifies the redirect layer.
QR typeBest forStatic or dynamic recommendationSpecialist page
URL / link Websites, landing pages, forms, social profiles, and campaigns Static for permanent links; dynamic for campaigns or changing pages Open the generator
WiFi Cafés, hotels, offices, classrooms, and event guest networks Usually static when credentials are stable WiFi QR code
vCard Business cards, networking, sales teams, and contact exchange Static for fixed details; dynamic if the profile changes often vCard QR code
PDF Menus, product manuals, brochures, reports, and downloadable guides Dynamic recommended when the document will be replaced PDF QR code
Email Support requests, inquiries, lead capture, and prefilled messages Static for a stable address and message template Email QR code
Link list Bio links, creator profiles, campaigns, and multiple destinations Dynamic so destinations can be managed without replacing the code Link-list QR code

Methodology note: recommendations prioritize edit risk, measurement needs, and the cost of replacing the printed asset. They do not replace the detailed guidance on each specialist page.

How Can You Create QR Codes for Common Scenarios?

For each scenario, prepare the final destination first and choose whether it may change after printing. Use specialist generators for structured payloads such as WiFi and vCard, and use dynamic links for campaigns, menus, or registrations that need editing or measurement.

Website or social link

Paste the complete HTTPS address and test it in a private browser window. A static link works for a permanent page; a dynamic code is safer when a campaign destination may change.

Create a link QR code

WiFi network

Enter the exact SSID, security type, and password, including capitalization. A café or hotel can print the tested code near reception while keeping staff or private networks separate.

Create a WiFi QR code

Business card contact

Create a vCard with the person's name, phone, email, company, and website. Test that both iPhone and Android offer a correctly populated contact before printing the card.

Create a vCard QR code

Restaurant menu or PDF

Upload the accessible menu PDF or link to a mobile-friendly menu page. Use a dynamic destination for seasonal changes so the table tent or window decal does not need reprinting.

Create a PDF QR code

Event registration or Google Form

Link a poster to the published registration form and verify that anonymous visitors can open it. Dynamic delivery helps if the venue page or RSVP form could change.

Create a form QR code

Payment or donation link

A nonprofit can link print collateral to a secure donation page it controls. Label the code with the organization and action, then use dynamic analytics when campaign measurement is required.

Review payment QR options

Product manual download

Link packaging to a hosted PDF or support page that remains available for the product's life. Use dynamic delivery when manuals receive revisions after products ship.

Create a manual QR code

Which QR Code Download Format Should You Use?

Download PNG for websites, email, and social media; download SVG for professional print, signage, and any layout that may be resized; use PDF when the QR code must be placed or shared as part of a document.
FormatBest forMain strengthWhat to watch
PNG Web pages, email, social posts, slides, and small print Widely supported raster image with simple placement Do not enlarge a low-resolution export or apply heavy compression
SVG Posters, packaging, signs, professional layouts, and large print Vector edges remain sharp at any output size Confirm the print or design tool preserves the full quiet zone
PDF Documents, print proofs, handoffs, and page-layout workflows Keeps the code inside a portable document context Check that export settings do not crop, downsample, or distort the code

In our 2026 workflow checks, vector SVG exports were the safest handoff for large-format resizing, while correctly sized PNG files worked well for digital placements. Scan reliability still depends on contrast, quiet zone, final size, and viewing distance.

The most expensive QR creation mistakes happen before printing: choosing static when a destination may change, encoding a typo, removing the quiet zone, using weak contrast, or skipping a scan test at final size.

What Common Mistakes Should You Avoid When Creating QR Codes?

  • Choosing static for a changing destination

    Use a dynamic QR code for menus, campaigns, event pages, or any target likely to change after the physical code is distributed.

  • Encoding a typo or inaccessible link

    Open the destination separately, check HTTPS, and test sharing permissions before generating. Static QR content cannot be corrected in place.

  • Using low contrast colors

    Keep dark modules against a light background and avoid gradients or busy images behind the QR pattern.

  • Cropping the quiet zone

    Preserve the blank margin on every side. Do not let a frame, trim line, image, or page edge touch the pattern.

  • Printing too small for the distance

    Test the exact production size from the expected scanning distance and consult the QR code size guide before a large run.

  • Skipping cross-device testing

    Test on iPhone and Android cameras, with typical lighting, before publishing or mass printing.

  • Assuming every export is equally reliable

    Use a reputable generator, preserve a lossless or vector master, and rescan after every design or export transformation.

A good QR code matches the correct payload type to the goal, keeps strong contrast, preserves the quiet zone, uses an appropriate file format, and passes real-device testing at its intended size before deployment.

What Are the Best Practices for QR Code Creation?

Treat the QR code as one part of the complete scan experience. The printed pattern, nearby call to action, landing destination, device compatibility, and ongoing destination ownership all affect whether a scan produces the intended result.

Plan before generating

  • Match the QR type to the intended action before entering data.
  • Choose dynamic for campaigns, menus, and links likely to change.
  • Use a destination you control and maintain for public-facing codes.
  • Confirm current dynamic feature terms before committing to print.

Design for scanning

  • Keep high contrast between modules and the background.
  • Preserve the complete quiet zone around the pattern.
  • Use logo overlays sparingly and retain adequate error correction.
  • Add a clear call to action that explains what the scan opens.

Export for the channel

  • Use SVG for professional print and large-format resizing.
  • Use a correctly sized PNG for digital channels and small print.
  • Keep a master export rather than repeatedly compressing copied images.
  • Check the QR code size guide for distance-sensitive placements.

Test and maintain

  • Scan on iPhone and Android at the final display size.
  • Confirm the destination loads quickly and matches the call to action.
  • Monitor dynamic destinations and analytics without collecting unnecessary data.
  • Follow deployment and placement guidance after creation.

How Did We Test QR Code Creation?

We tested QR code creation workflows and scan reliability across URL, WiFi, and vCard examples on iPhone and Android using QR-Build and common generator patterns in 2026.

Payloads reviewed

We generated representative URL, WiFi, and vCard examples, verified every input, and checked whether each scan produced the intended browser, network, or contact action.

Devices used

We scanned outputs with native camera experiences on iPhone and Android rather than assuming a result from the generator preview alone.

Visual checks

We reviewed contrast, quiet-zone preservation, resizing behavior, and common logo or compression risks across digital and print-oriented exports.

Decision criteria

Recommendations prioritize the cost of a broken print asset, likelihood of future destination edits, need for scan analytics, and suitability of PNG, SVG, or PDF delivery.

Many free generators can produce valid static QR codes quickly, and design platforms such as Canva and Adobe can fit QR creation into broader layout workflows. Verify current vendor capabilities, service terms, and plan limits directly before choosing a dynamic provider.

How Can You Create QR Codes with QR-Build?

QR-Build supports common static QR workflows and offers dynamic destinations, scan analytics, and design controls for use cases that need ongoing management. Choose the web generator for individual codes or the API for automated generation.

QR-Build is a QR code generator focused on practical payload types and managed campaign workflows. Simple static creation is appropriate for fixed content; a dynamic QR code connects a redirect layer to an editable URL and scan analytics when a team needs changes or measurement after publishing.

Common QR types

Create URL, WiFi, vCard, PDF, link-list, form, menu, and other QR experiences from one platform while keeping specialist inputs distinct.

Editable destinations

Use dynamic QR codes when the final destination may change after printing. Editability requires the associated service and account to remain active.

Scan analytics

Review aggregate scan activity for dynamic campaigns and connect that evidence to campaign decisions rather than assuming print distribution equals engagement.

Design controls

Apply brand colors, frames, and logo treatments while preserving contrast, quiet zone, and a testable production master.

What QR Code Creation Terms Should You Know?

The essential terms are payload, static QR code, dynamic QR code, redirect layer, quiet zone, scan analytics, PNG, SVG, vCard, and error correction. Understanding them prevents the most common type, editing, and export mistakes.

QR code

A QR code is a two-dimensional barcode that stores data in a pattern readable by compatible smartphone cameras and scanners.

Payload

A payload is the actual data represented by the QR pattern, such as a URL, WiFi configuration, vCard, text string, or contact action.

Static QR code

A static QR code encodes its destination or data directly in the pattern and cannot be changed without generating a new code.

Dynamic QR code

A dynamic QR code embeds a managed redirect URL, allowing the final destination to change while the printed QR pattern remains the same.

Redirect layer

A redirect layer is the intermediary URL embedded in a dynamic code that forwards each scan to the destination currently configured in the account.

Quiet zone

The quiet zone is the blank margin around a QR pattern that helps a scanner distinguish the code's edges from nearby artwork or text.

Scan analytics

Scan analytics are aggregate measurements of when, where, and how often a managed dynamic QR code is scanned.

PNG

PNG is a raster image format suited to digital placements and small print when exported at the correct pixel dimensions.

SVG

SVG is a vector image format that scales without losing sharpness, making it the preferred QR master for many professional print workflows.

vCard

A vCard is a structured digital contact record that can contain a person's name, phone number, email, organization, address, and website.

Error correction

Error correction is redundancy in a QR code that can help recover data when part of the symbol is damaged or obscured; it does not make unsafe designs automatically reliable.
