Use Resize Image for YouTube Thumbnail for ready-made YouTube sizes
This page is best when the main question is about a platform requirement and you want the preset immediately.
Use Image Resizer for custom canvas sizesSwitch to the generic resizer when the destination is not covered by the built-in preset list.
Use a KB target page after the preset if upload size still failsAfter setting the right dimensions, move to a file-size target page when the platform also enforces a strict upload limit.
Common questions
Are my images uploaded to a server?
No. Images are decoded, resized, and exported locally with browser APIs and canvas, so the file stays on your device during normal use.
Which YouTube sizes are built in?
YouTube thumbnail (1280 x 720).
Should I crop or fit the image?
Choose fill and crop when the platform layout matters more than preserving every edge. Choose fit when you need the whole source visible and are okay with padding.
