Can you compress a HEIC without converting it to JPG?
By EditItAll · Updated
No. Browsers cannot re-encode HEIC, so there is no smaller HEIC output. EditItAll's HEIC compress page converts the photo to JPEG or WebP at the quality you choose. The file does not stay .heic. That conversion also makes the photo open on Windows and on sites that reject HEIC.

Compress a HEIC photoWhy a browser cannot shrink a HEIC in place
No. Browsers cannot re-encode HEIC, so EditItAll cannot hand you a smaller .heic file. Compress a HEIC photo therefore converts the photo to JPEG or WebP at the quality you choose. The file does not stay .heic.
HEIC is what iPhones have shot by default since iOS 11. It is already smaller than an equivalent JPEG. Compressing it in a browser means leaving the format. There is no smaller HEIC output.
Read the format notes on HEIC if you want to know what the container is before you change it.
What the HEIC compress page actually writes
On /compress/heic you pick JPEG or WebP, then set a quality slider and an optional max-dimension cap. There is no target-file-size field. The page runs entirely in your browser: the photo is processed right on your device, and it works offline after the page loads. Nothing is uploaded. No account, no watermark.
The results list shows in to out size, rounded to whole KB. A readout of 20 KB can be 20.4 KB. Keep the original HEIC if you still want it.
- JPG is the file everything opens, including Windows and sites that reject HEIC.
- WebP is the smaller alternative when the destination accepts it.
When to convert to JPG or WebP instead
Use HEIC to JPG when you need a photo that Windows and ordinary sites will open. Use HEIC to WebP when the destination accepts WebP and you want the smaller file. Both paths leave HEIC behind, which is the only way a browser can shrink the photo.
The hub pages at /convert and /compress have no drop zone. Start on the exact pair page or on the HEIC compress page, drop the photo there, and choose quality before you download.
How to keep the original and still share a smaller file
Leave the iPhone HEIC untouched in your camera roll or files app. Export a copy, then compress that copy to JPG or WebP. The original stays HEIC, which is already the smaller capture format from iOS 11 onward.
- Open Compress a HEIC photo and drop the copy.
- Choose JPG if the recipient must open it anywhere, or WebP if the site accepts it.
- Move the quality slider, and set a max dimension only if you need a smaller pixel size.
- Check the rounded KB readout, download the new file, and keep the original HEIC.
