Convert to WebP.

Typically 25 to 50% smaller than a JPEG and 25 to 35% smaller than a PNG at the same visual quality: a 500 KB JPEG often lands near 300 KB. The exact figure depends on the picture and the quality you pick; the status line gives it for yours.

At the default quality of 80 the difference isn't visible. WebP's encoder is simply more efficient, so it reaches the smaller size without the softness and blocking a JPEG shows at a matching file size.

Yes. WebP has an alpha channel like PNG, so logos, icons and cut-outs convert with their transparent background intact and come out much smaller.

For the web, yes: every current browser reads it and nothing else gives a better size for the quality. Keep the originals for archive and editing, and serve WebP to visitors. For older browsers, a picture element can carry a JPEG or PNG fallback.

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.

One image at a time, since everything runs on your device. For a whole folder, convert each in turn, or put Sharp or a similar tool in the build pipeline.

Drop the image, leave WebP as the format, adjust the quality if you want, and download. The preview and the size line show the result before you save it.

No. The "Convert to WebP" tool is free and opens without a sign-in, an account or an install.

Nothing. The "Convert to WebP" tool 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.

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.
