Next-gen image format converter.

WebP, AVIF and JPEG XL: formats that compress better than JPEG and PNG. WebP has the widest support, over 97% of browsers, and is the one Lighthouse and PageSpeed Insights recommend adopting first.

Convert each flagged image to WebP here, download it and replace the original on the site, or serve the WebP through a picture element with the old file as fallback. Once the page's images are WebP the audit passes.

Usually 5 to 15 points on the performance score, more on image-heavy pages. A large hero image converted to WebP has the biggest effect, since it often decides Largest Contentful Paint.

WebP for now. AVIF compresses a little better but has less support, around 92% against 97%. Use WebP for the widest reach, and AVIF where you control the browsers; this tool writes AVIF too where the browser encodes it.

Safari 14, released in 2020, and later read WebP; Safari 13 and earlier don't, and are under 1% of traffic. All major CDNs serve WebP, and many convert and fall back to JPEG or PNG on their own.

No. The browser decodes the file, a canvas does the work and the result is built on your device; the page makes no request with your image. You can load it, go offline and keep working.

Drop the image, leave WebP selected, and download. Quality 75 to 85 is the range Google recommends; the preview shows what you'll serve.

No. The Next-gen image format converter is free and opens without a sign-in, an account or an install.

Nothing. The Next-gen image format converter holds your input in the page's memory, so closing or reloading the tab clears it, and it saves nothing in this browser.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

Yes. It has no Keep EXIF option: the re-encoded file carries pixels only, so camera, GPS and date fields in the original are dropped.

It always writes a new file in the format you picked, and the status line reports how much smaller or larger it is. If a Max size cap is still exceeded it says so and suggests lowering the side.
