Are my videos and images uploaded anywhere?

No. Everything runs in your browser — the frame is captured from a native video element and drawn onto a canvas locally. Your media never leaves your device and nothing is sent to a server.

What resolutions and formats can I export?

You can export 1280×720 (the recommended YouTube size) or 1920×1080, as either PNG or JPEG. JPEG adds a quality slider so you can shrink the file.

How do I stay under YouTube's 2MB thumbnail limit?

Switch the format to JPEG and lower the quality slider. The file size stat updates live and a warning appears when the result is over 2MB.

My video won't load — what now?

Frame capture relies on your browser's built-in video decoder, so some codecs (for example certain MOV or HEVC files) may not play. If capture fails, export a frame elsewhere and drop that image instead.

Can I add more than one line or block of text?

Yes. Add up to five independent text boxes, each with its own font, color, outline, shadow and position, and drag them anywhere on the preview.

YouTube Thumbnail Maker — Thumbnail Maker composites everything on an HTML canvas right in your browser, so your video and images never leave your device and are never uploaded to a server. Seek to the exact frame you want, lay bold captions over it, and download an upload-ready thumbnail in seconds.

What is YouTube Thumbnail Maker?

A YouTube thumbnail maker turns a video still or a photo into the 16:9 cover image that decides whether people click your video. This tool captures a frame straight from your uploaded clip with the native video player, then lets you fit the background, darken it for contrast, and stack outlined text so titles stay readable at small sizes. Creators, streamers, and marketers use it to produce a 1280×720 or 1920×1080 thumbnail without installing an editor or sending footage to a cloud service.

How to use YouTube Thumbnail Maker

Drop a video or image file, or connect one from another tool.
For a video, scrub the timeline and click Capture frame to freeze the shot you want; an image becomes the background instantly.
Choose Cover or Contain, zoom, and drag the image to reframe the focal point.
Add text boxes, pick the font, color, outline and shadow, and drag each caption into place on the preview.
Turn on the darken overlay or bottom gradient if the text needs more contrast.
Pick 1280×720 or 1920×1080, choose PNG or JPEG, and download the thumbnail.

Examples

Frame grab from a gameplay clip

Load an MP4, scrub to the highlight moment, capture the frame, and drop a two-line title with a thick black outline in the lower third.

Photo background for a tutorial

Use a product photo as a Cover background, add a dark bottom gradient, and place a bright yellow headline so it reads clearly on mobile.

Lightweight JPEG under the upload limit

Export at 1280×720 as JPEG and drop the quality slider until the file comfortably fits YouTube's 2MB thumbnail limit.
