Frequently Asked Questions
Is my image uploaded anywhere when using YouTube Thumbnail Maker?
No — everything runs on local canvas. The page opens the full photo editor pre-set to the 16:9 ratio; nothing leaves your device. Exception: the optional AI Describe button sends a small downscaled preview to Gemini (1 credit, stated on the button).
What size do YouTube thumbnails need?
1280×720px (16:9), JPG/PNG/GIF under 2 MB. Frame here, verify pixels in the Size readout, and compress to size if the export overshoots.
Can I start from a blank thumbnail?
Yes — open the full editor, start a blank 1280×720 canvas, add shapes and text, export. Same engine, same privacy.
