Tool Sets Correct Dimensions
Canvas automatically opens at 1280x720 pixels. No dimension settings to configure. Correct size every time.
People search for YouTube thumbnail dimensions because they have been burned. You make a thumbnail, upload it, and it comes back blurry, stretched, or rejected. Or it looks fine in the upload but displays wrong in search results because the safe zone is different from the full canvas size. Getting the dimensions right the first time saves hours of re-exporting and re-uploading across a year of content.
Never worry about dimensions again. Our canvas is automatically set to 1280x720 pixels in 16:9 ratio. Generate with the AI thumbnail generator or upload your own image - we handle sizing. Add text with the YouTube thumbnail editor and export ready for YouTube Studio. Sign in to start.
