Frequently asked questions
Are my images uploaded to a server?
No. Compression happens entirely in your browser using Canvas — your images never leave your device.
Which format gives the smallest file?
JPG and WebP compress photos far smaller than PNG. WebP usually wins on size at the same quality; PNG is best for graphics needing transparency.
