JPEG is high quality with a white background and smaller files; PNG keeps transparency and is larger.

Each picture is marked with the same settings and downloads separately, at its original size.

How it works

Stamping your mark, simply explained

A mark is your own logo or words drawn over a picture or video, so every version you post carries it. You choose one mark per run — a logo image, or text in your own words — and where it sits, how big it is as a share of the frame, and how see-through it is. Pictures keep their original size and download separately; a video comes out as MP4 at its original size. If you give both a logo and text, the logo is used and the text is ignored. Nothing else is added: no branding, no attribution, and the original files are never changed.
