Why convert JPG to WebP?
WebP is a newer image format from Google that was built to replace JPG on the web. For photos it usually reaches a similar look in fewer bytes, which means faster pages, lower bandwidth use and smaller email attachments. It also adds things JPG lacks, such as transparency, although a photo that starts as a JPG has none to carry over.
Both formats are lossy, so converting decodes the JPG and compresses it again. That second compression is a small cost, and it is why you should convert from your best original when you can and avoid converting back and forth.

How much smaller is a WebP photo?
It depends mostly on the quality you choose. We converted two JPG files with this tool. At the default of 90 both lost about a quarter of their size. At 75 the photo-like image fell to 11 percent of the original. Treat these as examples, not promises: well-compressed JPGs save less, and photos straight from a camera save more.
| Image | JPG | WebP at 90 (default) | WebP at 75 | WebP at 60 |
|---|---|---|---|---|
| Photo-like, 4032 x 3024 px | 2,179,008 | 1,606,142 (74%) | 239,288 (11%) | 123,044 (6%) |
| Flat illustration, 1200 x 800 px | 59,035 | 43,032 (73%) | 21,504 (36%) | 18,576 (31%) |
The photo-like image is our own sample scene scaled to 12 MP with seeded camera-like noise, saved as JPG at quality 92. The illustration is our sample scene saved as JPG. Percentages are the WebP size as a share of the JPG. A .jpeg copy of the photo gave the same result as the .jpg.
Which quality should I pick?
A WebP number does not match the same JPG number, so compare by eye on your own picture. For a web page, 75 to 85 is a common range and usually looks fine on screen. Use 90 or higher for images you may edit again, and go lower only for thumbnails or previews. Small files from a low setting can show blocky areas in smooth skies and skin.
If the JPG is already small or low quality, converting may save little, and in a few cases the WebP can even be larger at a high setting. Try a lower quality or keep the JPG.
- Camera data such as location is not copied to the WebP.
- Files up to 50 MB on a computer and 30 MB on a phone, with 30 per batch on a computer and 15 on a phone.
- WebP images can be at most 16,383 pixels on a side.
- To resize first, use the resize tool, then convert.
Does everything open WebP?
Every current browser shows WebP, and so do most modern phones, chat apps and design tools. Older software is the exception. Some print services, email templates, document editors and upload forms still accept only JPG or PNG, so check where the file is going before you swap formats.
Keep your original JPG as the master and treat the WebP as the copy you publish. If you need to go back, WebP to JPG does that.

Questions
How do I convert JPG to WebP?
Add your JPG or JPEG files to the box on this page, choose a quality and download the WebP results. A large photo takes about a second.
Does converting JPG to WebP lose quality?
A little, because both formats are lossy and the picture is compressed again. At quality 90 the difference is hard to see. Lower settings show more.
How much smaller is WebP than JPG?
In our test a 2.2 MB photo became 1.6 MB at quality 90 and 239 KB at quality 75. Results vary with the picture, and already compact JPGs save less.
Does it accept .jpeg files?
Yes. JPG and JPEG are the same format and the tool reads the file content, so both extensions work.
Can I use WebP on any website or app?
All current browsers support it. A few older programs, print services and upload forms do not, so check the destination first.
Will the WebP keep my location data?
No. Camera metadata, including location, is not copied to the WebP.
Are my photos uploaded?
No. The conversion runs in your browser and nothing is sent anywhere.
