Free QR Code Generator

Simply type or paste a URL or any text into the input field and a QR code appears instantly in your browser. Adjust size, error correction, and colors to match your brand, then download as PNG or SVG. Nothing is uploaded — generation runs entirely on your device so your links and messages never leave your browser session.

No. This tool generates QR codes entirely in your browser using client-side JavaScript. The text or URL you enter, the preview image, and any PNG or SVG downloads stay on your device. TryDoku does not receive, store, or log the content you encode, which makes the generator suitable for internal links, private event codes, and sensitive document references.

Error correction stores redundant data so a damaged or partially covered QR code can still scan. Level L recovers about seven percent, M about fifteen percent, Q about twenty-five percent, and H about thirty percent. Use L for clean digital screens, M for most print jobs, and Q or H when codes will be printed small, stamped on packaging, or may be scratched or obscured in the field.

Yes. Enable batch mode and paste one URL or text value per line. The tool creates a separate QR code for each non-empty line and lets you download them individually or as a single ZIP archive of PNG or SVG files. Batch generation also runs locally in your browser, with a safety cap on line count so large pastes stay responsive on typical devices.
