Questions
- What size should a YouTube thumbnail be?
- 1280×720 pixels, a 16:9 shape, under 2MB, as JPG, PNG or GIF.
- Is my image uploaded anywhere?
- No. The resizing happens in your browser. Your image never reaches our servers.
- Why did my PNG come out as a JPG?
- Some PNGs are too big to fit under 2MB at 1280×720. When that happens we save a JPG instead, so YouTube accepts it.
- What if my image isn't 16:9?
- We crop the largest 16:9 area from the center. Nothing gets stretched. For full control, crop it yourself first.
- Why won't my iPhone photo load?
- Most browsers can't open HEIC photos. Export it as JPG or PNG first (on iPhone, set Camera Formats to Most Compatible).
