Resize Image for YouTube

YouTube thumbnails are 16:9 and served at 1280 × 720, with 640 pixels as the minimum width. This page puts your artwork on that frame at the size you choose, so the file that reaches YouTube already matches the slot instead of being re-encoded at whatever quality the platform picks.

Frequently Asked Questions About Resize Image for YouTube

What size is a YouTube thumbnail?

1280 × 720 at a 16:9 ratio. Anything narrower is scaled up by the player and the search results, and anything off-ratio is cropped.

Does YouTube recompress the thumbnail I upload?

Yes, so start from a file that already fits the frame and check the version YouTube shows after processing rather than trusting your upload.

Will my original file be changed?

The result is downloaded as a separate file. Keep your original until you have checked the 16:9 YouTube frame.

What should I check before using the result?

Open the 16:9 YouTube frame in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.

About this workflow

Reading a thumbnail at 120 pixels wide

Most viewers see the thumbnail small and on a phone. After resizing, look at the result at that size — if the subject or the text is unreadable there, it is the file that needs changing.

Before downloading the result

Compare the 16:9 YouTube frame with the original while both are fresh; destinations differ, and a quick check here saves a re-upload later.
