Questions
Thumbnail preview questions
Is my picture uploaded anywhere?
No. The preview runs in your browser and your picture never leaves your device.
What size should a YouTube thumbnail be?
1280 × 720 pixels (16:9), under 2 MB, as JPG, PNG or GIF. Our free thumbnail resizer makes one from any picture.
Why check it small?
Most views come from phones and the Up next list, where a thumbnail is tiny. If it isn't clear small, it won't get clicked.
How long should a title be?
Titles can be 100 characters, but feeds cut them at around 50 to 70. Put the promise first.
Can it tell me which thumbnail is better?
