Your files are never uploaded — they’re processed right here in this browser tab, on your device. There’s no server involved, so we never see them, copy them or keep them.
How it works

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.

01

Add your HEIC photos

Drop in one or more photos straight from your iPhone.

02

Convert

Altto decodes and re-encodes each photo locally as JPG.

03

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.

  • Nothing is uploaded, everEvery photo is decoded and converted by code that runs in this browser tab, because there’s no server on the other end. That also means we can’t see it, copy it or keep it.
  • No account, no email wallConvert as many photos as you like without signing up or handing over an email address.
  • Batch conversion built inAdd a whole camera roll export at once and get them all back together.

photos stored on our servers. There’s no server involved at all — each JPG is built once, then everything happens locally.

FAQ

Frequently asked questions

The practical details on what this tool can and can’t do. Need PNG instead? See our other tools.

Why won't my iPhone photos open on my PC?
iPhones save photos as HEIC by default, a format most Windows apps and older software don’t support. Converting to JPG makes them open everywhere.
Is my photo uploaded anywhere?
No — nothing is ever uploaded. Every photo is decoded and converted entirely inside this browser tab. There's no server involved at all, so there's nothing for Altto to see, copy or keep.
Will I lose quality?
Choose Standard for everyday sharing (smaller files) or High for close-to-original quality (larger files) — either way, even Standard uses a high JPG quality setting.
Can I convert Live Photos or bursts?
Standard HEIC photos convert reliably. Some Live Photo and burst variants aren't supported yet — if one fails, try exporting it as a regular photo from your iPhone first.
Can I convert several photos at once?
Yes — add as many HEIC files as you like. One photo downloads directly; more than one comes back as a .zip.
Do you keep a copy of my photos?
No. There's no upload, so there's nothing on our side to keep. See the Privacy Policy for details.
