使用指南
Convert Apple HEIC photos to PNG when you need lossless quality or transparency: no new compression loss, every detail preserved, batch processing, all locally in the browser.
1. Batch flow
- Drop multiple HEIC/HEIF photos.
- Click Convert — PNG output is lossless (the quality slider does not apply).
- Download all results in one click.
2. When to pick PNG over JPG
Three scenarios: the photo still needs editing (every JPG re-save stacks losses; PNG does not); the image has transparency (JPG cannot store it); quality is a hard requirement (printing, archiving). For everything else JPG is friendlier in size — both tools are on this site.
FAQ
Yes. PNG uses lossless compression — no quality loss, though files are usually larger than JPG. Best for editing or quality-critical use.
No. Everything runs locally in your browser; no server is involved.
Expected. HEIC is an efficient lossy format while PNG is lossless; growing 2-5x is normal. Use HEIC to JPG for smaller files.
