HEIC to JPG
Turn an iPhone HEIC photo into a JPG for Windows and for upload forms. There is no way back: nothing here writes HEIC, and no encoder exists.
Runs on your device. The file is never uploaded.
HEIC to JPG decodes what an iPhone saved with libheif and writes an ordinary JPEG, the format every editor and viewer already reads. Windows machines and older software that turn the original away open the copy without complaint. The trip runs one way only: no wasm encoder for HEIC exists anywhere, so nothing here turns the JPG back.
Questions
Does HEIC to JPG upload my files?
No. HEIC to JPG runs inside this browser tab, in a Web Worker on your own machine, and no part of your file is sent anywhere. There is no upload step to skip — the tool cannot reach a server even if it wanted to, and the counter on the homepage shows the number of outbound requests the page has made: zero.
How many files can I use at once?
Drop as many as you like. Each file is handled separately and comes back as its own result, so twenty files in means twenty results out.
What can I change about the result?
One setting: quality (Quality 1-100). Defaults are filled in, so it runs without changing anything.
Is HEIC to JPG free, and do I need an account?
It is free and there is no account, no sign-in and no quota. Nothing is metered because nothing runs on a server — the only limit is your own device's memory, which is what decides how large a file it can handle.
Does it work offline?
Yes. The whole site is stored in your browser after the first visit, so HEIC to JPG keeps working with the network off. Tools that use a machine-learning model download that model once, on first use, and run offline afterwards.
Can I use HEIC to JPG outside the browser?
Yes. Every tool here is the same code on three surfaces: this page, a CLI command, and an MCP tool an AI agent can call. `heic-to-jpg` is the name it goes by on all three.
