Image Resizer for Social Media

Fit any image to the size each platform wants without squashing it: keep the whole picture over a blurred copy of itself (or a plain colour), or crop it to fill. Everything happens in your browser.

Which size where

YouTube thumbnails are 1280×720 and must be under 2 MB (save as JPG). TikTok, Shorts and Reels covers are 1080×1920. Instagram feed posts are 1080×1080 or 1080×1350 (portrait takes more of the screen). Check a thumbnail with the thumbnail checker.
