Convert JPEG to WebP
We turn JPEG 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
| JPEG | WebP | |
|---|---|---|
| Lossless | no | yes |
| Lossy | yes | yes |
| Transparency | no | yes |
| Animation | no | yes |
| Released | 1992 | 2010 |

JPEG
Good at
- Compresses photos tightly, and the loss is hard to notice
- Opens literally everywhere, including old devices and printers
- Fast to encode and open, easy on the device
Awkward about
- Lossy: every re-save degrades the image a little more
- No transparency — it turns white or black
- Visible halos appear around text and sharp edges
Use it when
- Photos that will not be edited further
- When the file has to open for absolutely anyone
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. JPEG → 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 JPEG hands over, including the gaps JPEG 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.
