To resize a YouTube thumbnail free: drop your image anywhere on this page, or paste it with Ctrl+V. It's resized on your device to fit 1280×720 at maximum quality, then compressed only if needed to land under YouTube's 2 MB limit. No upload, no signup.
Why your export was over 2 MB
Design tools default to PNG, and PNG stores your thumbnail's photo areas losslessly: enormous. YouTube accepts JPG at 1280×720, where even a busy thumbnail with text fits comfortably under 2 MB at visually perfect quality. We convert at maximum quality first and only step down if needed to clear the limit.

FAQ
Will my text stay sharp?
Yes. We resize to the exact display resolution first, so JPEG compression works on final pixels. Text survives far better than a blind compress.
My image isn't 16:9.
It's scaled to fit within 1280×720 preserving its shape. For a hard crop to 16:9, run it through resize first.
