Do the codes expire or have a usage limit?

No. A generated QR code is just an image holding exactly what you typed, and it works without going through this site. We neither track nor expire anything.

Which error correction level should I pick?

It is the redundancy that lets a code still be read when part of it is covered or damaged. A higher level is more robust but packs the same content into a denser code. M is fine on screen; Q or H suits print or a code with a logo in the middle.

Use PNG to drop straight into a web page or document, and SVG when the code needs to be enlarged, as for print. SVG is vector, so the edges stay crisp at any size.

Will it still scan if I change the colors?

Only if the code and background differ enough in brightness. If both are similarly light or dark, scanning degrades badly — after changing colors, always test with a phone camera.

What if a code in an image will not read?

Check that all four corners of the code are present, that the picture is in focus, and that the code is not tiny within the frame. A photo taken at a sharp angle, or with glare, can also fail.

Is my input or image stored on a server?

No. Generating the code and analysing the image both happen in your browser; nothing is transmitted.

QR code features

QR Code Generator — type a URL or text and the code appears immediately. Choose the size (256, 512 or 1024px), the code and background colors and the error correction level, then save as PNG or SVG or copy the image straight to the clipboard. SVG stays sharp at any size, which suits print. QR Code Reader — upload a photo or screenshot containing a QR code and its content is decoded for you. Drag and drop works, and so does pasting with Ctrl+V. Inverted codes (light on dark) are recognised too. Both generating and reading happen inside your browser; nothing you type or upload is sent anywhere.

How to use

1. On the Generate tab, enter a URL or text and the code appears at once. 2. Adjust size, colors and error correction if you need to. 3. Save as PNG or SVG, or copy the image to paste it directly. 4. To go the other way, open the Read tab and drop in an image or paste a screenshot.

When to use it

• Make a link QR code for a business card, poster or menu • Bridge an offline audience to an event page or survey • Create wifi or in-store information codes • Check where a QR code in an image actually leads before following it • Read a code shown on screen without reaching for a phone
