HEIC files: how to open and convert them
The format every iPhone has shot in since iOS 11: half the size of JPG, opened by almost nothing outside Apple's ecosystem.
What this site can do with HEIC
- Open and read: yes
- Write and convert to: no honest browser encoder exists
- Compression: lossy — a quality slider applies when encoding
- Transparency: supported
Decode only. No open-source browser-safe HEIC encoder exists, so we will never claim to write it.
