Step-by-step

  1. Open QR Code.
  2. Paste a URL, Wi-Fi string, vCard, or short note (up to 2,000 characters).
  3. Leave error correction on H unless you need a smaller symbol (M or L).
  4. Download PNG for screens or SVG for print. Content is deleted after the job.

Print tips

  • Keep a quiet zone (the white border). The tool defaults to 4 modules.
  • Use dark-on-light. Low-contrast colors fail cheap printers.
  • Test-scan the file on a phone before you send a large print run.

FAQ

PNG or SVG?

PNG is a large raster for slides and messages. SVG is vector — it stays sharp on a poster or business card at any size.

What does error correction H mean?

About 30% of the symbol can be damaged and still scan. ChargeBite defaults to H so printed codes survive folds and glare.
