File limits
Use JPG or PNG. Uploads from a phone are limited to 2 MB; larger files can be uploaded from a computer. JPG at quality 85–92 keeps 1280 × 720 thumbnails well under 2 MB.
Tips for thumbnails that get clicks
- Keep important text away from the bottom-right corner, where the video length appears.
- Use large, high-contrast text; thumbnails are often seen very small.
- Need to add text? Try the Thumbnail Maker or Add Text.
