How it works
QR code generator runs on this page, in browser memory. The file you choose is never sent to a server: it is read through the File API, processed locally and handed back as a download.
In three steps
- Choose a file from your device, or drag it onto the drop area.
- Adjust the options on the right, if the tool has settings.
- Press “Process locally” and download the result.
What it takes and what it returns
This tool accepts Text and produces PNG, SVG. The work is done by qrcode-generator.
Real limits
These limits come from what a browser can do safely, not from a paid plan:
- Around 2,900 characters at low error correction; fewer with accents or non-Latin alphabets.
What it does not do
Test the code with a phone before printing it. Weak contrast, too small a size, or printing on a curved surface can make it unscannable.
A QR code is not encrypted. A Wi-Fi password or contact details are written into it as plain text that anyone who scans it can read.
Common questions
Do my files reach a server?
No. Processing happens in browser memory. The network is used only to download the application's libraries, and your file's contents are not part of those requests.
Which formats does QR code generator accept?
It accepts Text and produces PNG, SVG.
Do I need an account?
No. The tool works without an account and without installing anything during the free pilot.
Does it work on a phone?
Yes, in current browsers. Very large files can exceed the memory a phone has available, in which case the job stops with a clear message.
