YouTube Channel banner requirements
The published requirements are already set. Add your image and FileBelow makes it match — 16:9 · at least 2048px wide · under 6 MB · JPEG or PNG.
JPG, PNG, WebP and HEIC. Your file is processed on your device.
The minimum upload dimension is 2048 by 1152 pixels at a 16:9 ratio, and the file must be 6 MB or smaller. YouTube recommends 2560 by 1440 for television displays. Only the central 1235 by 338 pixels is guaranteed visible on every device, so keep text and logos inside that area.

What these numbers mean in practice
The minimum upload dimension is 2048 by 1152 pixels at a 16:9 ratio, and the file must be 6 MB or smaller. YouTube recommends 2560 by 1440 for television displays. Only the central 1235 by 338 pixels is guaranteed visible on every device, so keep text and logos inside that area.
A banner that fails to upload leaves the channel with a blank grey header, and one designed without the safe area in mind gets its text cropped off on phones.
How FileBelow applies them
Choosing this destination sets every rule above at once. After processing, the result panel shows one line per rule with a pass or fail beside it, so you can see that the file genuinely complies rather than hoping it does.
Where the specification sets a minimum size rather than an exact one, FileBelow keeps as much resolution as it can while meeting the other rules, and never scales below the stated minimum.
