YouTube thumbnail resizer FAQ
What are the correct dimensions for a YouTube thumbnail?
1280×720 pixels (16:9), at least 640 wide, under 2 MB. One click on the preset gets you a compliant export.
Can I resize an image without stretching or distorting it?
Yes. 'Cover' fills the frame with a smart crop; 'contain' fits the whole image with padding. Neither squashes it out of proportion.
Which file format should I export, JPG or PNG?
JPG for photos (smallest file), PNG for graphics and text (crisp edges), WebP when it's just for preview (most efficient).
Does the resizing happen on your servers?
No. Resizing runs in your browser via canvas, so nothing is uploaded and your file stays put.
How do I get a thumbnail under the 2 MB limit?
Export as JPG and drop the quality slider. Around 80% stays sharp while landing well under 2 MB.
