About the JPG to WebP tool
WebP files are typically 25–35% smaller than JPG at the same visual quality, which means faster pages and better Core Web Vitals. Convert any JPG to WebP instantly.
Re-encoding runs on your device using the browser's WebP encoder. No upload, no account, no stored copy.
How to use it
- Add your JPG files.
- Pick a quality level — 75–85 suits most photographs.
- Download the converted WebP.
What you gain, and the one thing you lose
WebP at the same perceived quality is typically 25–35% smaller than JPG on photographs, which is a meaningful saving on a page carrying a dozen images.
The catch is that JPG is universally accepted while WebP, though supported by every modern browser, is still refused by some upload forms and older software.
What the numbers look like
Measured on the same 1600×900 image: JPG at quality 80 came to 51 KB, WebP at quality 80 came to 21 KB. That is 58% smaller — an unusually large gap, because this particular image was graphic-heavy. Photographs generally land closer to the 25–35% range.
Common mistakes
- Re-encoding at high quality and expecting the file to shrink dramatically. WebP at quality 95 can be larger than the JPG you started with.
- Converting images that will be uploaded to a site that only accepts JPG and PNG.
- Converting the same photo repeatedly through different formats — each lossy pass degrades it further.
Questions people ask
Will the image lose quality?
A lossy-to-lossy conversion always loses a little. At quality 80 the difference is generally invisible at normal viewing size.
Can I convert back to JPG later?
You can, but you will not recover detail lost in either compression step. Keep your original.
Is WebP good for photos on a website?
Yes — smaller files at the same visual quality is exactly what page-speed scores reward.
