Convert HEIC to JPG.
Turn iPhone photos into JPGs that open on any device — batch convert as many as you like, without a single photo leaving your device.
Three steps, no waiting on a server
Altto's HEIC to JPG tool works right in your browser tab, so there's no upload queue and no “processing your file” spinner tied to someone else's servers.
Add your HEIC photos
Drop in one or more photos straight from your iPhone.
Convert
Altto decodes and re-encodes each photo locally as JPG.
Save your JPGs
One photo downloads directly; several come back as a .zip.
Why this runs in your browser, not on a server
Photos are often the most personal thing on your phone — not something you’d want sitting on a stranger’s server just to change the file format. Altto skips that step completely — there’s no server for it to go to.
