YouTube Video watermark requirements
The published requirements are already set. Add your image and FileBelow makes it match — 1:1 · at least 150px wide · under 1 MB · PNG or JPEG.
JPG, PNG, WebP and HEIC. Your file is processed on your device.
A square image of at least 150 by 150 pixels, under 1 MB. This is the subscribe badge shown in the corner of your videos, so a simple high-contrast mark reads far better than a detailed logo at that size.

What these numbers mean in practice
A square image of at least 150 by 150 pixels, under 1 MB. This is the subscribe badge shown in the corner of your videos, so a simple high-contrast mark reads far better than a detailed logo at that size.
The watermark is a subscribe button; if it will not upload, that prompt simply never appears on any of your videos.
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.
