Compress HEIC photos with a before and after slider
Shrink a HEIC photo by lowering quality or aiming at a target size, and judge the result with a before and after slider. The tool says plainly when no saving was achieved.

How to use it
- Add your HEIC files.
- Pick an output format. HEIC is offered only when your browser has an HEVC encoder. Otherwise choose JPG, WebP or AVIF, which are clearly labelled.
- Set a quality value, or enter a target size.
- Compare with the slider, check the size shown, then download.
What it keeps
- Pixel dimensions, since compression here does not resize. Use Resize HEIC for that.
- Visible orientation.
- Date and camera fields if you choose to keep them.
What it removes or changes
- Re-encoding is lossy. Each pass discards more detail than the last.
- HEIC photos are already efficient, so the result may not be smaller. The tool reports when no saving was made, and the original is then the better file.
- If you switch to JPG, WebP or AVIF, the format changes along with the size.
Limits
- HEIC output depends on the HEVC encoder built into your browser and operating system, reached through WebCodecs. FromHEIC distributes none, for patent reasons.
- It has been verified in Google Chrome on macOS. Without an encoder, the HEIC option is disabled and explained.
- Limits: 200 MB per file, 100 megapixels, 200 files.
Compatibility
A compressed HEIC works on Apple devices and where HEVC decoding exists. If the file has to travel to people on unknown systems, choosing JPG is more reliable, even if the file ends up a little bigger. WebP and AVIF suit websites you control.
Privacy
Re-encoding happens on your device, using codecs in the page or your browser. Photos are not uploaded and nothing is stored after you close the tab.
Lower quality, smaller dimensions or a new format?
Three levers shrink a photo. Quality saves a little with small visible cost until it drops too far. Dimensions save the most, if you do not need the full pixel count: a photo viewed on a phone screen rarely needs the full sensor resolution. A new format like WebP or AVIF can help, at the price of compatibility. For a hard size cap, the target size tool searches for it directly.
Troubleshooting
The compressed file is bigger than the original.
The phone already encoded the photo efficiently. Keep the original, lower quality further, or resize the photo.
The HEIC option is greyed out.
Your browser has no HEVC encoder. Use JPG, WebP or AVIF instead.
The compressed image looks blocky.
Quality is too low. Raise it until the slider comparison looks clean.
Frequently asked questions
Can compression make a HEIC larger?
Yes. The tool tells you when that happens.
Do I need a particular browser for HEIC output?
You need one that exposes an HEVC encoder. Chrome on macOS is verified.
Can I hit an exact size?
Use the target size option or the HEIC to target size tool.
