Frequently asked questions

Is my image uploaded to a server?

No. The conversion runs entirely in your browser with the Canvas API, so your image never leaves your device.

Which formats are supported?

It reads any image your browser can open and exports JPG, PNG or WebP. JPG flattens transparency onto white; PNG and WebP keep it.

JPG, PNG or WebP, which should I pick?

JPG suits photos, PNG suits graphics and transparency, and WebP usually gives the smallest file at similar quality.
