FAQ
Frequently Asked Questions
What if my image is smaller than 1280x720?
Tool will upscale it, but quality suffers. Best to start with images at least 1280x720 or larger.
Can I resize square images for YouTube?
Yes. Square images get cropped to 16:9 or you can add fill color on sides. Your choice.
What about portrait orientation photos?
Same options. Crop to 16:9 focusing on key area, or add fill on sides.
Does resizing hurt quality?
Downsizing keeps quality. Upsizing loses some. Start with larger images when possible.
Can I resize multiple thumbnails at once?
Yes. Batch upload supported. Set crop rules and process multiple images together.
What is YouTube recommended thumbnail size?
1280x720 pixels at 16:9 aspect ratio. Under 2MB file size. This tool exports exactly that.
