JPG to WebP Converter
Convert JPG (JPEG) images to WebP for free. WebP files are usually much smaller at the same quality, so your pages load faster. Pick the quality, see the size saved, and download — all in your browser.
How to convert JPG to WebP
- Choose a JPG or JPEG file from your device.
- Set the WebP quality — 80–90% keeps photos visually identical to the original in most cases.
- Compare the original and WebP sizes and check the percentage saved.
- Download the .webp file, and keep the JPG as well if you'll need it for email or printing.
JPG vs WebP at a glance
| Feature | JPG | WebP |
|---|---|---|
| Compression | Lossy only | Lossy or lossless |
| Transparency | No | Yes |
| Animation | No | Yes |
| Maximum size | 65,535 × 65,535 px | 16,383 × 16,383 px |
| Typical file size | Baseline | About 25–34% smaller at equal quality |
| Support | Every app and device | All current browsers; most, but not all, desktop apps |
The size figure comes from Google's published WebP study, which compared lossy WebP with JPG at matching visual quality.
Avoiding double compression
A JPG has already been through lossy compression once. Converting it to lossy WebP compresses it a second time, and each round discards a little more. At high WebP quality the second loss is invisible; at low quality the two sets of artefacts stack up, and the result can look worse than either format would on its own.
So convert from the best source you have — the original camera JPG rather than a copy downloaded from social media or already shrunk — and don't push the slider too low. If you need a much smaller file, reduce the pixel dimensions first instead of dropping WebP quality below about 70%.
Using WebP on a website
Every browser in current use displays WebP; Safari was the last major one to add it, in 2020. If you still want a fallback for very old browsers or for services that scrape your pages, the HTML picture element lets each browser choose: list the WebP in a source element marked as image/webp and keep the JPG in the img element. Browsers that understand WebP take it, and everything else falls back to the JPG.
WordPress has accepted WebP uploads since version 5.8, so on many sites you can simply upload the converted file in place of the JPG.
Frequently asked questions
Why convert JPG to WebP?
WebP usually produces a smaller file than JPG at the same visual quality, which speeds up websites and saves storage.
Is quality lost?
WebP is very efficient; at high quality the difference is hard to see while the file is noticeably smaller. You can adjust the quality slider.
Do all browsers support WebP?
Yes — all modern browsers display WebP. A few very old apps don't, in which case keep a JPG copy.
Are my images uploaded?
No. Conversion happens entirely in your browser.
Should I convert every photo on my website to WebP?
For photos that load on your pages, yes — smaller images mean faster pages and less data for visitors on mobile. Keep the original JPGs as source files, and leave images people download or print, such as brochures or press photos, as JPG.
What quality setting should I start with?
80% is a good starting point for photos. Compare the preview at full size: if you can't see a difference, try 70%; if fine texture looks smudged, go up to 85–90%.
Why doesn't the conversion work in my browser?
Some browsers — Safari in particular — can display WebP but can't create WebP files from a web page. When that happens the tool tells you, instead of quietly handing you a PNG with a .webp name. Open the page in Chrome, Edge or Firefox to convert.
Does converting remove the photo's metadata?
Yes. The WebP is created from the pixels only, so EXIF details such as the camera, capture time and GPS location aren't copied — useful for privacy when you publish photos online.
