Batch convert a whole iPhone export of HEIC photos (free)

Exporting your iPhone library or AirDropping a vacation's worth of photos leaves you with a folder full of .heic files that half your apps can't open.

With ConvertFlow you drag the entire selection into the page at once. Every file gets its own row with a target-format picker; hit Convert once and each file shows its own progress. When done, "Download all (.zip)" packages every result.

All of it happens locally: the HEIC decoder is WebAssembly running in your browser tab. A few hundred photos convert in minutes on a normal laptop — and zero photos touch the network.
