Frequently asked questions
Why is my iPhone saving photos as HEIC?+
Apple switched to HEIC by default in iOS 11 to halve photo storage requirements. You can revert to JPEG by going to Settings → Camera → Formats → Most Compatible, but this doubles storage use per photo.
Does converting HEIC to JPG lose quality?+
Minimal visible loss at 90%+ JPEG quality. The WASM decoder reads HEIC perfectly; the only change is that HEIC's HDR metadata is tone-mapped to standard JPEG range. For web and print, the difference is indistinguishable.
Is my photo data private when I convert HEIC here?+
Completely. The conversion runs in your browser tab — no bytes are sent to any server. Your image, filename, and GPS data stay on your device. If you want to strip location data from the output, run it through the EXIF Scrubber tool after conversion.
Privacy first
All image processing runs locally in your browser using WebAssembly and the Canvas API. No file is ever uploaded — only metadata counters are saved for signed-in dashboard stats.
