Questions and answers
Before you trust the result: what to know about the format, the limits, your data and the tools next to it.
Not every WebP is encoded well. Files from cameras, design tools and exports often use cautious settings; re-encoding at 75 to 80 typically takes 20 to 40% off with no visible change.
75 to 80 for most sites: excellent quality, smallest practical file. Use 85 for hero images where quality shows most and 65 to 70 for thumbnails and non-critical images. Google's own guidance is 75 to 85.
Directly. Smaller images load sooner, which improves Largest Contentful Paint, one of the Core Web Vitals Google uses in ranking. An optimized WebP helps both the score and the visitor.
Yes, when the image is larger than it is shown. A 4000-pixel image displayed at 800 pixels wastes bandwidth; set the longest side to the real display size and combine it with the quality for the biggest saving.
Below about 60 you may see blocky patches and banding. The preview is the real output, so adjust until it's the smallest file that still looks right.
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.
No. The WebP optimizer is free and opens without a sign-in, an account or an install.
Nothing. The WebP optimizer 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.

The WebP optimizer is one of 44 in its group. The group's page, /tools/webp, lists them all.
The tool is free. Its interface is built from shadcn.io's own components (Button, Input, Slider and the rest of the registry under /ui), which come in React, Vue, Svelte and Solid. Pro adds the blocks and templates for the product around it.
