How image compressor works
Re-encodes raster pixels with a selected JPEG or WebP quality level. Compare output bytes to decide whether the result is useful.
Try an example
A 2400 × 1600 photo can be re-encoded at quality 80 to trade some detail for fewer bytes.
Good to know
A smaller file is not guaranteed. PNG quality is not adjustable. JPG, PNG and WebP only; 25 MB and 24 megapixels maximum. Output is a single still frame; animation, source colour profiles and metadata are not preserved.
