I kept getting rejected thumbnails because the dimensions were wrong. This just exports at the right size automatically. Problem solved.

All my photos are square from Instagram. Now I can turn them into YouTube thumbnails without the weird cropping. AI extends the background.

The smart cropping is actually smart. It keeps my face visible instead of cutting off my head like other tools do.

Batch resizing 50 thumbnails for my old videos took maybe 20 minutes. Would've been hours doing it manually.

Best Practices
Tips for Making Great Thumbnails
Start with larger images. Resizing down keeps quality. Resizing up creates blur.
Use AI crop suggestion first. Usually picks good framing. Adjust if needed.
Check important elements are not cropped. Faces, text, key objects should stay visible.
Preview at actual size before downloading. What looks good zoomed may not work small.
Export PNG for images with text. JPG for photos only. PNG keeps text sharper.
Common Mistakes
What to Avoid
Uploading tiny images and expecting good results. Start with at least 1280x720 source.
Stretching to fit instead of cropping. Stretched images look wrong. Crop properly.
Ignoring what gets cut off. Important elements at edges may get cropped. Check carefully.
Resizing multiple times. Each resize loses quality. Resize once from original.
Forgetting about mobile display. Resize result still needs to work at small sizes.
