foldmintChoose a QR code that fits the job
A website code opens a URL. A text code contains a short note. A Wi-Fi code encodes network details in a format understood by many phone cameras and QR readers. These are static codes: the contents go directly into the pattern.
PNG or SVG?
PNG is a pixel image. Choose 512 or 1024 pixels for most on-screen uses. SVG is a vector file that remains sharp when resized, which makes it useful for print artwork. The generated code includes a white quiet zone around its edges; do not crop it away.
Make your code easy to scan
- Use a short, correct destination where possible. Long text creates a denser pattern.
- Keep the black-on-white contrast and the surrounding white border.
- Test the actual download on at least one phone before printing or distributing it.
- Test again at its final physical size and viewing distance. There is no single size that works for every placement.
The generator uses medium error correction. It does not add logos that cover modules or decorative patterns that reduce readability. A code that scans in a large preview might fail if printed too small or placed on a curved, reflective surface.
Your link stays your link
There is no Foldmint redirect, tracking URL or subscription attached to the code. A URL must begin with https:// or http://. Check spelling carefully: QR codes do not verify that a destination is safe or that you own it. Wi-Fi passwords and text are generated locally and are not included in usage events.
The encoder is the open-source node-qrcode library. For other everyday file tasks, try JPG to PNG or PDF to Word.
