❓ Frequently Asked Questions
What size are the thumbnails? ▼
All thumbnails are created at 1280×720 pixels — the recommended YouTube HD thumbnail size. This ensures crisp quality on all devices.
Can I use a custom background image? ▼
Yes! Click "Upload custom background image" to use your own photo or image as the thumbnail background. Works great with screenshots or action shots.
JPG or PNG — which should I download? ▼
For YouTube upload, JPG is recommended as it has a smaller file size while keeping great quality. PNG is lossless and best if you want to edit further in other software.
