Frequently asked questions
What is the correct image size for YouTube video thumbnails?
1280×720 pixels. This preset applies that size automatically when you load an image.
Will resizing distort my photo?
If your photo has a different aspect ratio than 1280:720, it will be stretched to fit. For a distortion-free result, crop it to the right ratio first with the Crop Image tool, then resize.
Is my image uploaded anywhere?
No. Resizing happens entirely in your browser using the canvas API — the file never leaves your device.
