About Resize for YouTube
A YouTube thumbnail that is the wrong size shows up blurry or gets letterboxed, and a channel banner that ignores the safe area gets its text cut off on phones and TVs. These specs matter for how professional your channel looks.
This tool resizes your image to YouTube's thumbnail and banner dimensions so it displays crisply everywhere. It is free, runs in your browser, and never adds a watermark or asks you to register. The image is handled on the spot and not stored, giving you a ready-to-upload file in seconds.

FAQ
What thumbnail size does YouTube want?
The standard thumbnail is 1280x720 pixels with a 16:9 shape, which this tool produces for clean display.
Why is the banner so large?
Banners are sized big so they stay sharp on large TVs, while key text should sit in the central safe area to avoid cropping on small screens.
Will resizing blur my thumbnail?
Downscaling a larger image stays sharp. Start with a high-resolution image for the best-looking result.
Does it keep the right aspect ratio?
Yes, it matches YouTube's 16:9 thumbnail and banner proportions so nothing looks stretched.
Can I use Resize for YouTube on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
