How It Works

This tool creates a payment payload (a plain address or a network-specific URI) and then renders it as a QR code image. A QR code is simply a visual encoding of text data; most camera apps and wallet scanners can decode it instantly. You paste an address, select the currency/network, and optionally add amount, label, or message. The generator builds the correct URI format and produces a QR you can scan to fill the recipient field without retyping.

Step-by-step

• 1) Choose network: Select Bitcoin, Ethereum, Litecoin, Solana, Tron, or a generic option if you only need the raw address.
• 2) Paste address: Add the wallet address exactly as provided by your wallet or exchange.
• 3) Add optional details: Include an amount, label (recipient name), or message for the payer.
• 4) Generate: The tool creates a payment URI (when applicable) and encodes it into a QR image.
• 5) Copy or download: Copy the URI/text payload or download the QR code image for sharing.

What gets encoded? The QR content can be either the raw address (for maximum compatibility) or a URI that includes a scheme and optional parameters. For example, Bitcoin commonly uses bitcoin:ADDRESS?amount=1.23&label=Name. Ethereum wallets often accept ethereum:ADDRESS?value=... in some contexts, but support varies, so keeping the payload minimal can be beneficial. Solana and other ecosystems may prefer raw addresses. That is why the tool lets you choose a network and decide how much metadata to include.

Encoding and error correction: QR codes include built-in error correction so they can still be scanned if part of the code is smudged or partially hidden. The more data you include, the denser the QR becomes, which can reduce scan reliability on small prints or low-quality screens. To keep scanning easy, use the shortest payload that still meets your needs and avoid unnecessary text in label/message fields.

Scan safety: A QR code reduces typos, but it does not eliminate scams. Always confirm that the decoded address matches the intended recipient, especially if you are copying an address from an untrusted source. When receiving payments, publish your address in multiple places (for example, your official website and social bio) so senders can cross-check if they suspect tampering.

Key Features

Wallet-friendly payment URIs

For networks that support URI schemes, the tool formats a scanner-ready string such as bitcoin: or ethereum: with optional query parameters. This improves compatibility with wallet apps that expect an address plus metadata.

Clean QR preview and instant regeneration

See a clear QR preview right after generation so you can validate the content and scan it with a phone before sharing. Regenerate quickly if you change amount or label.

Copy payload for invoices and buttons

Beyond the QR image, you can copy the exact payload (address or URI) to embed in “Pay now” links, payment buttons, invoices, email templates, and checkout instructions.

Download-ready image output

Download a PNG version of your QR so it can be used in presentations, PDFs, print flyers, stickers, or social posts. The tool is designed to provide an output you can use immediately without additional editing.

Supports common sharing formats

Use the QR as a standalone asset, embed it in a PDF invoice, place it next to a “Copy address” button, or pair it with a short text label for clarity. The included payload text output helps you keep the QR and the readable address in sync so recipients can verify visually.

Better scanning in real-world conditions

High-contrast QR codes scan faster. For screen use, keep the QR large enough and avoid compressing the image excessively. For print, avoid glossy materials that introduce reflections. The downloaded PNG is suitable for most everyday needs, and you can scale it in design tools while keeping sufficient quiet zone (empty margin) around the QR.

Privacy-first workflow

You control what goes into the QR payload. If you do not want an amount or note embedded in the QR, leave those fields empty and generate a QR that contains only the address or base URI.

Use Cases

• Personal payments: Share a QR with friends so they can scan and send funds without copying a long address.
• Freelancers and creators: Add a QR to invoices or “Support my work” pages with an optional label or message.
• Merchants: Display a QR at checkout for fast crypto payments and fewer errors at the register.
• Events and donations: Put a QR on posters, slides, or badges so attendees can donate in seconds.
• Customer support: Provide a verified QR in help articles to reduce mistakes caused by typos or formatting issues.
• Print materials: Create sticker-ready QR codes for packaging inserts or product manuals.

Whether you are collecting one-off transfers or publishing a public donation address, a QR code reduces friction and helps prevent copy-paste errors. Always scan-test your QR with at least one wallet app before distributing it widely.

Team wallets and accounting: If you manage multiple addresses across networks or departments, QR codes make it easier to route payments correctly. Combine a label like “Marketing wallet” or “Support wallet” with a clean QR so your team and customers pick the right destination every time.

QR on mobile screens: If you show a QR on your phone for someone else to scan, increase brightness and avoid moving the device. On some screens, very small QRs can become difficult to scan due to pixel grid and glare; consider generating with fewer optional fields to keep the code less dense.

QR in video streams: Streamers can show a donation QR on screen. In that scenario, keep the QR steady for several seconds, ensure it has enough size, and avoid overlays that cut into the quiet zone. Test scanning from different distances before going live.

Optimization Tips

Prefer URIs when your wallet supports them

If your recipients typically pay using wallet scanners, including an amount or label in the URI can improve the payment flow. However, if you need maximum compatibility across exchanges and different scanners, using the raw address or a minimal URI is often the safest option.

Scan-test on multiple devices

Different camera apps and wallet scanners interpret QR codes slightly differently. Before printing or posting publicly, scan the QR on iOS and Android if possible, and confirm that the decoded payload matches exactly what you intended.

Keep the payload concise

QR codes become denser as the text gets longer. Shorter payloads create larger modules and scan more reliably, especially on small screens or in print. If you do not need label and message, omit them for a cleaner code.

Pair QR with a readable address

For best practice, display the human-readable address below the QR so the payer can verify the first and last few characters after scanning. This is especially useful on websites and invoices where users may be cautious about scanning and want to confirm the destination.

Use consistent naming

If you include a label, keep it consistent across your public materials. A predictable label helps recipients recognize that they scanned the right code (for example, “Acme Coffee BTC” vs “Acme Coffee ETH”). Consistency also helps when you support multiple networks.
