#FAQ
How does image compression work in the browser? ▾
The tool draws your image onto a Canvas and re-encodes it using canvas.toBlob() with a quality parameter between 0 and 1. Lower quality values produce smaller files with more visible compression artifacts.
Which formats support quality-based compression? ▾
JPEG and WebP formats support lossy quality adjustment. PNG is a lossless format and does not benefit from a quality slider, so the tool converts to JPEG or WebP for compression.
