Is my file uploaded when converting HEIC to JPEG?

No. The conversion runs entirely in your browser. The file never leaves your device, there is no server to upload to, and the page works offline once loaded.

Is HEIC to JPEG conversion free?

Yes, with no account, no watermark and no file limit per day. frogConvert is open source and there is no server cost to recover, because your device does the work.

How large a file can I convert?

Up to 2 GB for a single file, 500 MB total per batch, and 300 files at once. The practical limit is your device's memory, since everything is processed locally.

Convert HEIC to JPEG

Converts an iPhone photo to JPEG so it opens anywhere. HEIC stores stills using HEVC video compression, which is why the originals are roughly half the size.

Convert HEIC to JPEG →

Runs on: ImageMagick, compiled to WebAssembly, running in this tab
Steps: Direct, a single conversion
Input: .heic · image/heic
Output: .jpg · image/jpeg
Uploads: None. The file never leaves your device.

What to expect

JPEG is less efficient, so the converted file is usually larger than the HEIC it came from. Live Photo motion and depth data are not carried over.

Why convert HEIC without uploading

Most online converters take your file, send it to their servers, convert it there and hand back a download link. That means your document sits on someone else's disk, subject to their retention policy and their breaches. It also means you cannot use them offline, and cannot use them at all for anything confidential.

frogConvert does the conversion in the page itself, with ImageMagick compiled to WebAssembly. There is no upload step because there is no server. You can disconnect from the network and it still works.

About the formats

HEIC

Apple's default photo format since iOS 11, storing still images with HEVC video compression at roughly half the size of a comparable JPEG. Patent licensing is why support outside Apple's ecosystem stayed thin. More about HEIC files.

JPEG

The dominant photographic format, using discrete cosine transform compression that discards detail the eye is least likely to notice. It has no transparency, and every re-save loses a little more. More about JPEG files.
