PNG is lossless — the quality slider does not apply. To reduce file size, set a max width or choose JPG/WebP output.
A page loads only as fast as its heaviest image, which is usually the first place worth checking before optimizing anything else. Add a JPG, PNG, or WebP file, move the quality slider, and see the original size next to the new one before deciding whether to download. The image is re-encoded at the quality setting you pick, and the tool reports exactly how many bytes were saved — or warns you if the new file actually turned out larger than the original. Not always. A JPG that's already well optimized can even grow slightly if the quality setting is too high for its content. Exporting through canvas typically strips EXIF metadata, so location and camera details won't carry over to the new file.What this tool does
