Convert JPG images to WebP in your browser and cut the weight of your web pages. Quality slider, both sizes shown, batches in one ZIP. No upload.
Your files are processed in your browser, on your own device. Nothing is uploaded to a server.
This tool converts JPG images to WebP in your browser, aimed squarely at one job: making web pages lighter. WebP was built by Google for exactly this, holding the same picture in fewer bytes than JPG manages. If a speed report has ever told you to serve images in next-gen formats, this page is the answer to that line item.
The quality slider starts at 92. For site photos, many people land between 75 and 85 once they compare the two sizes side by side: a picture that looks the same on screen at a weight visitors on slow connections actually feel.
The figure quoted across the web, from Google’s own comparisons, puts WebP at about 25 to 34 percent smaller than JPG at the same quality. Real files vary around that figure, sometimes beating it and sometimes falling short. Some JPGs barely shrink at all, and it helps to know why. A JPG that is already tiny has little left to give. A grainy, noisy photo is full of random detail the encoder must faithfully store, and noise is expensive in any format. A clean product photo or a smooth graphic shrinks beautifully. A grainy night shot may come back nearly the same size, and since the tool shows both sizes on every file, you can judge each one yourself instead of taking a promise on faith.
Hero images are the biggest prize, because the hero is so often the largest thing on the page and the element the largest contentful paint score waits on. Product photos, blog illustrations and gallery images follow. WordPress has accepted WebP uploads since version 5.8, and every current browser displays the format. Cautious sites still serve the old JPG to the rare visitor on outdated software, using the picture element to offer both. That pattern only works if you keep the originals, which is why step five above exists. For a mixed set of PNG graphics with transparency, PNG to WebP does the same job on that side.
Conversion redraws each picture from its pixels. Camera and location metadata stored in the JPG stays behind, which for images published on the open web is usually what you want anyway. A saved rotation is read and applied, so phone photos stand upright in their new format. And the work happens here, in your browser: nothing is uploaded to a server, no account is involved, and there is no daily cap on any of the image converters. If a file ever has to become a document instead, the converted set can ride along into Image to PDF afterward.
Most photos land around 25 to 34 percent smaller at the same quality, matching the figures Google publishes for the format. Clean graphics often do better. Grainy or already tiny JPGs may barely shrink, and the tool shows both sizes so you can see the truth per file.
Photos sit happily between 75 and 85 for web use. The slider starts at 92, a safer pick for hero images and anything with fine detail. Compare the result size at two settings and let your eyes decide.
Yes. WordPress has supported WebP uploads since version 5.8, and media libraries treat it like any other image. Older plugins occasionally grumble, but the core platform is fine.
Every current browser opens WebP. Genuinely old software may not, which is why careful sites keep the JPG and serve it as a fallback through the picture element. Keep your originals and you keep that option.
Grain and noise are the usual cause. Random detail costs bytes in every format, so a noisy photo gives WebP little room to win. A file that was already very small has the same problem. It is the picture, not the tool.
No. The conversion runs in your browser on your device. Nothing is sent or stored, there is no sign-up, and no watermark touches the output.
Same rules as this one: free, in your browser, with nothing uploaded.
