About Image Compressor

Re-encode a raster image at full resolution using a chosen lossy quality. WebP usually offers good compression and preserves transparency; JPEG replaces transparency with white. Savings depend on the original and can be negative.

How to use it

  1. Select an image and choose WebP or JPEG.
  2. Set image quality; 85 is a quality-focused starting point.
  3. Compress, compare sizes and inspect the result.

Frequently asked questions

Will compression always reduce size?

No. A highly optimized source may already be smaller. Compare the output to the original before replacing it.

Is the result identical to the original?

No. JPEG and this WebP mode are lossy; repeated re-encoding degrades quality. WebP keeps transparency; JPEG does not.
