Frequently Asked Questions
How does Image Well Done compress images without uploading?
Modern web browsers possess powerful graphics capabilities. We use Canvas and native browser encoders directly on your computer hardware to compress the pixel data.
Why does PNG not compress with a quality slider?
The PNG specification is strictly lossless. To compress PNGs effectively, we provide an option to convert to WebP, which preserves transparency while shrinking file sizes dramatically.
What quality setting is recommended for web images?
A quality level between 75% and 82% typically reduces file size by 60–80% with no noticeable loss in visual clarity on standard and retina screens.
