Questions and answers
Before you trust the result: what to know about the format, the limits, your data and the tools next to it.
For photographs, WebP at the same visual quality is usually 25 to 35 percent smaller than JPEG: a 100 KB JPG often lands at 65 to 75 KB with no visible difference. Images with large flat areas save even more.
75 to 85 usually matches the look of the JPG it came from. Going higher cannot add detail the JPG never had, it only grows the file; going lower starts to show in gradients and around edges. The before and after previews let you judge.
Every current browser: Chrome, Firefox, Safari since version 14 in 2020, Edge and Opera. For a page that must still serve the last old browsers, a picture element with a JPG fallback covers them.
For most sites, yes: the saving is pure page speed, and large sites have served WebP for years. A CDN or build step can do it automatically; this tool is for the one-offs and for checking what a given quality looks like.
Nothing. They are one format, defined by the Joint Photographic Experts Group in 1992. The three-letter extension dates from Windows systems that allowed no more, and every tool here takes both spellings.
Drop the JPG, move the quality slider and read the new size and the percentage saved under the result. The image is re-encoded on each change, so you can find the lowest quality that still looks right before downloading.
No. The WebP is written from the decoded pixels and carries no EXIF data. Keep the JPG if the camera data matters.
No. The file is decoded, drawn and re-encoded by your browser's canvas, and the page makes no request with it. You can load the page, go offline and keep working; nothing is stored either.
No. The JPG to WebP converter is free and opens without a sign-in, an account or an install.
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.
It draws the image on a canvas and asks your browser to encode WebP. If your browser can't, the tool says 'This browser can't write WebP.' instead of saving a wrong file.
No. The result has the same width and height in pixels as the source.
