Free Static QR Code Generator

How to create and check your QR code

1. Choose the action. Select Text, Website, Email, vCard, SMS or WiFi. Use Website for a page you maintain; use Text for a short message that does not need a website.
2. Enter only what the reader needs. Include https:// in a website address. For a contact, start with first and last name, then add the details you intend to share. Longer content creates a denser code.
3. Keep the first version simple. Start with black on white and no logo. Choose an image size between 100 and 500 pixels. Size here is the exported image width, not a guaranteed print size or scanning distance.
4. Generate and export. Press Generate QR Code after changing your data or settings. Download PNG for everyday use; read the export notes below before choosing SVG or PDF.
5. Scan the exported file. Check both the decoded content and the action on the intended devices. For print, also test a physical proof at its final size.

Worked examples: what should a scan do?

These are demonstration values, not real contact or network credentials. A phone may show a confirmation screen rather than perform an action automatically.

Wi-Fi caution: the password is readable from the QR image. Use a guest network you are authorized to share, not a private or administrative network. Enterprise Wi-Fi and WPA3-only settings are not offered by this tool. WEP is a legacy option, not a recommended security choice.

Colors, quiet zones and error correction

Keep the squares dark and the background light. The contrast preview measures text contrast; its AA or AAA label is not a certification that a QR code will scan. Reflective paper, low light, a small print size or a dense payload can still make a code unreadable.

Preserve the clear border around all four sides. This generator uses a four-module margin, also called the quiet zone. Do not crop it away or fill it with text, artwork or a frame.

These percentages refer to recovery of codewords, not the percentage of image area you can safely cover. There is no universal safe logo size. A logo that obscures a finder pattern or too much data may break scanning even at High correction. If a code fails, remove the logo first. Higher correction does not compensate for printing the modules too small.

Choose an export format with its limitations in mind

• PNG: a raster image at the selected size. Avoid enlarging a small PNG or converting it to a heavily compressed JPEG, which can blur the module edges.
• SVG: this implementation wraps a PNG image inside an SVG file. It is not a true vector QR code and does not gain unlimited sharpness when enlarged.
• PDF: places a raster QR image at 50 mm wide on a PDF page. The underlying resolution still matters. Print without unexpected scaling and scan a proof.
• Copy: image clipboard support depends on the browser, a secure connection and permissions. Download a PNG if clipboard copying is unavailable.

No single printed dimension works for every code. A short URL, a long contact card and a distant poster have different requirements. Use the final artwork, material and viewing distance for your test rather than relying on a minimum-size promise.

A pre-publication checklist

1. Open the destination yourself. Check HTTPS, spelling, redirects and whether a login is required.
2. Scan the downloaded image on more than one intended device or reader, not just the live preview.
3. Print a sample at the final size with its quiet zone intact. Test under likely lighting and distance.
4. Check the actual action: correct contact fields, message recipient or guest-network connection.
5. Add a plain-text URL or short explanation beside the code so people know what to expect and have an alternative if scanning fails.
6. Keep the source data and recheck linked pages after publishing. Changing a website address, mailbox or Wi-Fi password can make old printed codes unusable.

Troubleshooting by symptom

The camera cannot recognize the code

Remove the logo, return to black on white and restore the clear border. Increase the image or printed size. If the pattern is very dense, shorten the content and generate again.

A link scans, but the page does not open

Include the full https:// address. Check the decoded URL, internet connection, domain and destination page. A readable code cannot repair a broken website.

Email, SMS or a contact appears as raw text

The reader may not support that payload or may lack a configured app. Try the intended phone's camera or another trusted reader. Check contact fields before distributing a vCard.

Wi-Fi is recognized, but connection fails

Check the network name's spelling and case, password, encryption and Hidden setting. Confirm that the network is nearby and supports the selected authentication type.

The exported code is blurry

Generate a larger PNG and avoid resizing or lossy recompression. The SVG and PDF exports here contain raster images, so changing the file extension does not restore lost detail.

QR data, browser history and privacy

The generator builds QR images in your browser; its generation code does not upload the entered text or selected logo to a QR-generation server. That is separate from visiting this website: the site includes third-party advertising scripts that make network requests.

After generation, the tool can save up to ten recent entries in this browser's localStorage under qrHistory. Entries include a type, timestamp, text preview and QR image reference. An image can expose the full encoded content, even if the text preview is shortened. History has no automatic time-based expiry. Avoid sensitive content on a shared device.

Clearing history does not delete downloaded images, clipboard contents or copies you shared. Anyone with a QR image may decode it; a QR code is not encryption. When a reader opens a link, the destination's own privacy practices apply.
