Questions and answers
Before you trust the result: what to know about the format, the limits, your data and the tools next to it.
Yes. WordPress 5.8 and later accept WebP in the Media Library like any image. Older versions need a plugin such as WebP Express or ShortPixel to serve it.
For speed, yes. A WebP is 25 to 50% smaller than the JPEG or PNG it replaces, which shows directly in page speed and Core Web Vitals. Keep the originals as a backup and upload the WebP versions.
75 to 80 for most sites. Photography sites can go to 85; a blog with many images per page keeps pages fast at 70 to 75.
Faster images improve Largest Contentful Paint, one of the Core Web Vitals Google ranks on. Smaller images also cut bounces from slow pages, so WebP helps both the ranking and the visitor.
Yes. Don't upload a 4000-pixel photo for an 800-pixel content column. Set the longest side to your theme's content width: with the WebP compression on top, the file is a small fraction of the original.
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.
Current themes and caching plugins serve WebP to browsers that read it and a JPEG or PNG to the rest, on their own. Over 97% of visitors have a browser that reads WebP, so you can also just upload the WebP.
No. The "WebP for WordPress" tool is free and opens without a sign-in, an account or an install.
Nothing. The "WebP for WordPress" 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.
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.
