Convert JPG to WebP
Output is typically about 34% smaller.
- Files stay on your device
- No upload, no waiting
- No sign-up, no watermark
How it works
Add your JPG file
Drag a JPG file onto the drop zone, or click to browse. You can select several at once.
Choose your settings
Adjust the quality slider if you want a smaller file or a sharper result. 80 suits most photographs.
Download the WebP
Conversion runs on your device as soon as each file is added — no upload, no queue. Download each result when it is ready.

Will converting JPG to WebP make the file smaller?
Usually, yes. A 12-megapixel photo is around 3.2 MB as JPG and around 2.1 MB as WebP — about 34% smaller. Because WebP is lossless the result depends entirely on the image content — flat colour and text compress far better than photographic detail.
Does converting JPG to WebP lose quality?
Slightly. Re-encoding one lossy format as another means a second round of compression, which can soften fine detail. In practice the loss is hard to see at high quality settings, and WebP's newer codec often preserves detail better than the JPG original did. Keep quality at 80 or above and the difference will not be visible at normal viewing size.
Is WebP safe to use on a live website?
Yes. Every browser in current use supports it — Chrome since 2014, Firefox since 2019, and Safari since version 14 in 2020. Coverage is above 97% of global traffic. The remaining gap is older desktop software and some print workflows, so keep a JPEG or PNG original if the image also has to leave the web.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using your own device's processor. Your JPG file is never transmitted anywhere, which means there is no upload wait, no file size cap, and nothing for us to store or leak. You can disconnect from the internet after the page loads and it still works.
About jpg to webp
Why convert JPG to WebP?
JPEG has been the default photo format for three decades, and its compatibility is unmatched — if a device can display an image at all, it can display a JPEG. The trade-offs are that it discards detail permanently on every save, and it has no transparency channel at all, so anything transparent becomes a solid background.
WebP is the pragmatic modern choice for the web: roughly 25–35% smaller than JPEG at comparable quality, with transparency and animation that JPEG lacks, and — since Safari 14 in 2020 — support in every browser that matters. It is the format to reach for when you want smaller pages without worrying about fallbacks.
JPG and WebP side by side
| JPG | WebP | |
|---|---|---|
| Full name | JPEG | WebP |
| Compression | Lossy | Lossy or lossless |
| Transparency | No | Yes — alpha channel |
| Animation | No | Yes |
| Browser support | Universal — every browser, every device | All modern browsers — Chrome 32+, Firefox 65+, Safari 14+ (2020), Edge 18+ |
| Typical 12 MP photo | ~3.2 MB | ~2.1 MB |
| Usually used for | Photographs, email attachments and anything needing maximum compatibility | Web images where page weight matters and modern browsers are the audience |
On a typical 12-megapixel phone photo, the WebP output comes out about 34% smaller than the JPG original. Your own results will vary with the image — flat colour, text and line art behave very differently from photographic detail, and the quality slider moves the figure substantially.
What you gain
- 25–35% smaller than JPEG at equivalent visual quality
- Supports both lossy and lossless modes in one container
- Alpha transparency, including on lossy images
- Animation support, as a far smaller replacement for GIF
What to watch out for
- Not accepted by some older desktop software and print workflows
- Slightly slower to encode than JPEG
- Larger than AVIF at the same quality
How the conversion works here
Your file is decoded and re-encoded entirely inside your browser on a background thread, so the page stays responsive even with a large batch. Nothing is uploaded, which means there is no size limit imposed by us, no queue, no watermark, and no copy of your image sitting on someone else’s server afterwards.
Because it runs locally, the tool keeps working if you lose your connection after the page has loaded — useful on patchy mobile data, and the reason this approach suits anything sensitive.
