Do these QR codes expire?

No. The QR code encodes your content directly, so it works forever and isn't tied to any server or tracking redirect. "Dynamic" QR services that promise editable links route through a redirect that can break or start charging — this tool does not.

Can I download a vector QR code?

Yes. Download as SVG for print or large displays where it scales without pixelation, or PNG for everyday on-screen use.

Is my data sent anywhere?

No. The QR code is generated entirely in your browser.

What is the error-correction level and which should I choose?

Error correction adds redundant data so the code still scans if part is damaged or covered. L recovers 7%, M 15%, Q 25%, and H 30%. Use M for general use; choose H if you plan to overlay a logo or print on a surface that may get scuffed.

What size should the QR code be?

You can set 80 to 1024 pixels. For print, a rough rule is the code should be at least one tenth of the scanning distance — about 2-3 cm for phone scanning at arm's length. Keep a quiet (blank) margin around it.

Can I use custom colors?

Yes, you can set the foreground and background colors. Keep strong contrast — a dark pattern on a light background scans best. Low-contrast or inverted (light on dark) codes often fail to scan.

What can I encode in a QR code?

Any text works, including plain URLs, phone numbers (tel:), email, and structured strings such as WiFi credentials (WIFI:S:name;T:WPA;P:pass;;) or vCard contact data. The phone's camera interprets the format.

QR Code Generator — Gera Tools

Generate QR codes that never expire

This generator encodes your content directly into the QR image — no redirect server, no tracking, and no expiry — so the code keeps working as long as QR codes exist. It’s for anyone putting a link, WiFi password, or contact card on a poster, menu, label, or slide who wants a permanent, downloadable code.

How it works

The tool runs the open-source qrcode library locally. Your text is rendered onto a <canvas> and exported to a PNG via canvas.toDataURL("image/png"), and separately rendered as an SVG string for a vector download. You control the pixel size (80–1024), the foreground and background colors, and the error-correction level, which sets how much redundancy is built in so the code still scans when partly obscured.

Example

Encoding https://gera.tools at 320 px with level M produces a code with ~15% error correction — enough to survive a small smudge or a tight crop. Bumping to level H raises that to ~30%, the right choice if you place a logo in the centre.

Error-correction levels

Level	Recovery	Best for
L	7%	Clean digital displays
M	15%	General use (default)
Q	25%	Printed labels that may scuff
H	30%	Codes with a logo overlay

Everything is generated locally in your browser — your content is never uploaded.
