HEIC to JPG
HEIC to JPG conversion, with the quality and size consequences stated up front.
Why convert HEIC to JPG
Newer iPhones capture in HEIC, which stores the same visual quality in roughly half the bytes — but much Windows software and many web forms still refuse it.
What you give up
JPEG output will be larger for the same quality, and any depth or live-photo data is discarded. Whether this works at all depends on whether your browser exposes a HEIC decoder.
When it is the right move
Use it to make iPhone photos usable in a form, an editor or a print workflow that expects JPEG. If your browser cannot display the HEIC in the first place, it cannot convert it either — use the phone or the operating system.
Size, honestly
Expect roughly double the byte count, because HEIC's compression advantage is being given up.
Why this runs in your browser
The file is read from your disk by the browser, decoded with the browser's own codecs, and re-encoded in this tab. No upload request is made, nothing is queued on a server, and closing the tab leaves no copy anywhere. You can verify this in the network panel while it works.
How to use it
- Drop one or more HEIC files on the drop zone.
- Set the output format to JPG.
- Convert and check the reported before-and-after file sizes.
- Open the result and check transparency and edge detail before shipping it.
Worth knowing
- Output format is JPG and input is read as HEIC.
- Size expectation for this direction: Expect roughly double the byte count, because HEIC's compression advantage is being given up.
- Conversion happens in the browser; no file leaves your machine.
- Metadata is discarded by the canvas round-trip.
Limitations
- JPEG output will be larger for the same quality, and any depth or live-photo data is discarded. Whether this works at all depends on whether your browser exposes a HEIC decoder.
- Animation is not preserved when converting from an animated source.
- Converting between two lossy formats compounds compression artefacts.
- Writing JPG depends on your browser exposing that encoder.
