Thumbnail Maker

Thumbnails, Shorts covers, banners and profile pictures from your visualizer, a video or a picture. Your files stay on your device.

1. What is the thumbnail for?

A video file

Any MP4 or WebM, including your Sonic Weaver exports. It opens on this device and is never uploaded.

A visualizer project

Thumbnails are rendered by the editor that made it, at your song's strongest moments. Open a project, then Export → Thumbnail.

Open ClassicYour projects

A picture

A photo, your cover art or artwork. Add text, a logo and stickers on top.

Start blank

A colour background and a title, for a banner, an announcement or a channel picture.

Four steps

How it works

  1. Bring your video or visualizer

    A video file, a picture, or a project: the editor renders frames from your song's strongest moments.

  2. Pick from eight suggestions

    Each pairs a strong frame with a layout that leaves room for the title. Press More for others.

  3. Make it yours

    Change the words, fonts and colours, add your logo, shapes and stickers, and move anything.

  4. Download at the right size

    Every format stays under the platform's file limit, as a PNG or a JPG.
