Compress images and check the real savings

Quality is a tradeoff

Lower JPG or WebP quality can reduce file size but can soften text, edges and fine detail. The slider is an encoder quality setting, not a target file size. Start around 80 and inspect the result.

Smaller is not guaranteed

Re-encoding an already optimized image can make it larger. A different format can also increase size. Each output shows original bytes, output bytes and the actual percentage change.

Keep your original

The tool creates new files and does not modify your originals. Keep your source files so you can try another setting without repeatedly compressing a compressed result.
