Frequently asked questions
How does image compression work?
For JPG and WebP, the compressor re-encodes your image at a lower quality setting, which removes detail the eye barely notices and shrinks the file. For PNG, it reduces the number of colors and optionally scales the image down.
Will compression reduce image quality?
Some quality loss is unavoidable when shrinking a lossy file, but at moderate settings the difference is hard to see. Always compare the preview before downloading.
Are my images uploaded to a server?
No. All processing happens locally in your browser; your images never leave your device.
