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 should I use for web images?
Try a setting around 75–82% for JPG or WebP, then compare the visual result and file size. The best choice depends on the source image.
