Resize a YouTube thumbnail.
Settings
We adjust quality and dimensions automatically to hit your size. Pick the output format under Export settings — JPG and WebP compress best.
Your photo is center-cropped to the exact size — no stretching — and saved as JPG. Set a max size for portals that reject files over a limit, like 50 KB.
YouTube thumbnails must be 1280 × 720 and under 2 MB. Both are handled here — drop your artwork and download a ready-to-upload thumbnail.
- Photos are resized on your device — nothing is uploaded
- Hit an exact file size like 20 KB, not just a smaller one
- Passport and portal presets, cropped without stretching
How it works.
- 1Drop your thumbnail artwork into the box — 1280 × 720 is pre-set.
- 2Tap Resize thumbnail. If your source isn’t 16:9, crop it first with the 16:9 preset in our crop tool.
- 3Download and upload straight to YouTube Studio.
Frequently asked questions
What are YouTube’s thumbnail requirements?
1280 × 720 pixels (16:9), under 2 MB, in JPG, PNG, GIF, or BMP. This tool outputs 1280 × 720 well below the size cap.
My image isn’t 16:9 — will it be distorted?
With both width and height set and aspect lock on, the width wins and the ratio is preserved. For an exact 16:9 frame without distortion, crop to 16:9 first using our crop tool, then resize here.
JPG or PNG for thumbnails?
JPG is smaller and fine for photographic thumbnails. Use PNG when your design has sharp text or flat graphics that must stay crisp.
