Frequently asked questions
Are my images uploaded anywhere?
No. Every image tool processes your photo locally on your device using the HTML canvas API. Nothing is uploaded.
Which formats can I convert between?
PNG, JPEG and WebP, with a quality control for lossy formats.
How much can I compress an image?
Typically 50–80% for photos at a quality of 70–80% with little visible difference. The tool shows the before and after sizes.
