Convert HEIC to WebP
We turn HEIC into WebP right in your browser — the file never goes to a server.
What you will lose
Nothing to lose, and nothing to gain: {to} keeps exactly what {from} hands over, and the file grows several times over.
How they differ
| HEIC | WebP | |
|---|---|---|
| Lossless | yes | yes |
| Lossy | yes | yes |
| Transparency | yes | yes |
| Animation | yes | yes |
| Released | 2015 | 2010 |
| Author | MPEG |
HEIC
Good at
- Half the weight of JPEG at the same quality
- Stores burst frames, depth maps and live photos
- The default capture format on iPhone since 2017
Awkward about
- Opens poorly outside Apple devices
- Patent constraints hold back browser support
- Many sites and forms simply refuse these files
Use it when
- Keeping photos inside the Apple ecosystem
- When you want the most quality per byte
WebP
Good at
- 25–35 % lighter than JPEG at comparable quality
- One format instead of three: lossy and lossless, transparency, animation
- Supported by every browser released after 2020
Awkward about
- Older software and devices will not open it
- Some editors still cannot save to it
Use it when
- Images for the web — the main case
- Replacing JPEG, PNG and GIF with a single format
Common questions
- Does the file get uploaded to a server?
- No. HEIC → WebP runs right in your browser and the file never leaves your device. It only goes to a server if the browser cannot cope — and then we delete it within a couple of hours.
- Will transparency survive?
- Yes, WebP supports transparency, so semi-transparent edges stay as they were.
- Can I get the original quality back afterwards?
- Nothing is lost, but nothing is gained either. WebP stores exactly what HEIC hands over, including the gaps HEIC left behind when it compressed. No tool can bring those back, and the file grows several times over. This conversion makes sense for editing, not for quality.
- How many files, and how large?
- Up to 30 files at a time, 50 MB each. No sign-up, no watermarks.
