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 important: the target format does everything the source does.
How they differ
| HEIC | WebP | |
|---|---|---|
| Lossless | yes | yes |
| Lossy | yes | yes |
| Transparency | yes | yes |
| Animation | yes | yes |
| Released | 2015 | 2010 |

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?
- Yes, WebP supports lossless compression, so you can go back to the original.
- How many files, and how large?
- Up to 30 files at a time, 50 MB each. No sign-up, no watermarks.
