HEIC is Apple's efficient image format used by default on iPhones since iOS 11, but it often fails to open or upload on Windows, older Android devices, and many websites due to limited support. You can instantly convert these HEIC photos to the universally compatible JPG format without uploading your private images anywhere, using our free in-browser tool.
Windows 10 (version 1803+) and Windows 11 can open HEIC files if you install Apple's HEIF/HEVC extensions from the Microsoft Store, but many apps and websites still won't accept the format — converting to JPG guarantees it opens everywhere without any extra installs.
Both HEIC and JPG use lossy compression, so re-encoding can introduce a tiny amount of quality loss, but at a high quality setting the difference is visually negligible for everyday photos. JPG files are usually larger than the original HEIC because HEIC compresses more efficiently.
Yes — FileZap converts everything locally in your browser using the built-in canvas engine, so nothing is ever uploaded to a server. Your family photos never leave your device, which is why it's safe even for private or sensitive images.
