Quick answer
To make a YouTube thumbnail or 720p HD frame, resize your image to 1280×720 pixels. Open Resize Image with the 1280×720 preset, drop your JPG, PNG, or WebP, and download — everything happens on your device, not uploaded to our servers for processing.
- Convert HEIC if needed — iPhone photos are often HEIC. Use HEIC to JPG first.
- Resize to 1280×720 — open the tool with this size pre-filled and download the result.
- Compress if there's a size cap — some uploads also limit KB. Use Compress Image after resizing.

- 1280×720 is the size YouTube asks for, but it is almost never the size anyone sees. In a sidebar or a phone feed the same image renders a few hundred pixels wide.
- Design for the small version: few words, high contrast, one clear subject. Then check it by shrinking your own file to about 250 px wide and looking again.
- Thumbnails also have an upload size cap, so a heavily detailed PNG may need converting to JPG before it is accepted.
There is also a file-size limit here. Dimensions alone are not enough for this destination — resize to 1280×720 first, then use Compress Image to bring the file under the cap. Compressing before resizing wastes the compression, because changing the pixel dimensions re-encodes the file anyway. Platform limits change, so confirm the current figure on the upload screen itself.
