Convert JPG to WEBP
Turn a JPG image into WEBP right in your browser. WEBP usually makes photos even lighter than JPG while keeping the quality, which is great for speeding up sites and saving bandwidth. The conversion happens on your device, without sending anything to servers.

How to convert JPG to WEBP in 3 steps

Is swapping JPG for WEBP worth it?
JPG is already light, but WEBP usually goes further: for the same quality level, it produces even smaller files. On sites with many photos — portfolios, stores, galleries — that saving adds up and makes pages load faster.
Lighter pages improve the visitor's experience and help SEO. That's why WEBP has become the preferred format for images on the modern web.
When WEBP is worth it
For web use, WEBP is almost always worth it: less weight, same look. It's supported by all modern browsers, so the visitor sees the image normally.
If the image is going to an old program, a legacy system or someone who needs to open it anywhere without thinking, JPG is still the safest bet. For anything web, WEBP wins.
A recompression, not an improvement
Both formats use lossy compression. Converting a JPG to WEBP means decoding an already-compressed image and compressing it again, which can add a small amount of degradation on top of what was already there.
In practice, at high quality, that is imperceptible — and the space saving usually justifies the trade. But it is the reason converting back and forth between lossy formats repeatedly makes no sense.
The typical gain and where it counts
A WEBP usually lands 25% to 35% smaller than the source JPG at equivalent visual quality. On a site with many images, that translates directly into faster pages and less data used by visitors on mobile.
For publishing on the web, the gain is real. For archiving, or sending to someone who will open it in an older program, JPG remains the safer bet. The conversion happens on your device.
When in doubt, keep the original JPG: the WEBP is for publishing, and the original is for generating other versions later.
Use cases
- Make the photos on a site or portfolio lighter
- Save bandwidth on a gallery or store with many images
- Speed up page loading (and help SEO)
- Optimize images already in JPG for the modern web
- Reduce the space taken up by a set of photos
Frequently asked questions
Is the WEBP smaller than the JPG?
In most cases, yes — with equivalent quality. That's why WEBP is so widely used on the web.
Does the photo's quality drop?
The conversion uses high quality (92%); for photos displayed on the web the difference is imperceptible.
Do all browsers open WEBP?
All modern browsers support WEBP. Very old programs may not recognize it — in that case, prefer JPG.
When should I keep JPG?
When the image needs to open in any program, including old systems. For the web, WEBP is more efficient.
