Keys are stored in this browser only. A key lets you buy credits and keep going after the free runs.
How it works
- Type or paste the text or URL you want to encode into the input field, then set the format, size, margin, error-correction level, and colours.
- Press Run.
- Download the PNG or SVG that appears.
Limits
Input is capped at 4,096 bytes. Each visitor gets 20 free runs a day with no login required. Beyond that, each run costs 1 credit drawn from a prepaid balance tied to an API key.
Privacy
The input is processed for the request and discarded afterwards; it is not kept or used for anything else. Usage records store only time, tool, status, duration, credits, and a salted hash of the IP.

Questions
Do I need an account to use this?
No. You get 20 free runs a day as a visitor with no login. An API key is only needed once those free runs are used up.
What happens after my 20 free runs?
Each additional run costs 1 credit drawn from a prepaid credit balance attached to your API key.
Can I call this from code?
Yes. POST your parameters to https://data.voiddo.com/v1/qr_code; a curl example is shown on this page. The same free tier applies before credits are required.
Is the text or URL I submit stored?
No. The input is processed for the request and discarded immediately. Nothing you submit is retained or used for any other purpose.
What output formats are available?
The tool returns either a PNG file or an SVG file; for PNG you can also set the edge length in pixels.
