How to create a high-quality QR code (PNG or SVG)
A tiny on-device canvas QR often fails in print. ChargeBite encodes with segno at high error correction so a poster, card, or slide still scans.
Updated 2026-09-08
Step-by-step
- Open QR Code.
- Paste a URL, Wi-Fi string, vCard, or short note (up to 2,000 characters).
- Leave error correction on H unless you need a smaller symbol (M or L).
- 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.
