Frequently asked questions

Which formats can I convert between?

JPG, PNG and WebP in any direction. Every result is checked against the format you asked for before a download is offered.

Why does a JPG export ask for a background colour?

JPG cannot store transparency, so transparent areas have to be flattened onto a colour. Choose the colour the image will sit on so the join is invisible.

Does converting to WebP lose quality?

WebP and JPG both re-encode at the quality you pick, while PNG keeps every pixel. Re-encoding is lossy, so keep the original file and convert once.
