What is YouTube Banner Resizer?

YouTube Banner Resizer crops and resizes your images to the exact 2560×1440 YouTube channel art dimensions. The safe area overlay shows how your design appears on TV, desktop, tablet, and mobile.

YouTube serves your channel art at three different aspect ratios depending on the viewer's device. The overlay visualises all three: the full 2560×1440 canvas, the 1546×423 desktop safe area, and the central 1546×423 mobile/TV strip. Drag, zoom, choose JPEG, PNG, or WebP output, and the tool encodes the result right on your device.

How to use

1. Upload your banner image or design.
2. Position and scale your image within the 2560×1440 canvas. The safe area guides show what's visible on each device.
3. Download the properly sized banner ready to upload to YouTube.

When to use

• Centering a logo and tagline inside the 1546×423 mobile safe area so nothing important gets cropped.
• Resizing a Twitch or Twitter banner to fit YouTube's 2560×1440 canvas without warping the artwork.
• Producing a fresh banner under YouTube's 6 MB upload ceiling without re-encoding in Photoshop.

Result

A YouTuber uploads their brand graphic and uses the safe area overlay to position their channel name and social links within the 1546×423 safe zone visible on all devices.

FAQ

What's the difference between the desktop, TV, and mobile safe areas?

YouTube crops your banner differently depending on the viewer's screen. The full 2560×1440 only shows on TV. Desktop browsers crop to roughly 2560×423, and phones show the central 1546×423. Anything outside that mobile box is invisible to most viewers.

Why does YouTube reject my upload as too large?

YouTube caps channel art at 6 MB. A full-quality PNG of 2560×1440 can easily go over. Export as WebP for the smallest file at the same quality, drop the quality slider to around 85, or keep PNG only when your design has flat colours and sharp edges.

Can I upload a transparent PNG so my channel page background shows through?

No. YouTube flattens any transparency to black on upload, which is why most channels use a solid colour or full-bleed photo. If you need a transparent feel, blend your design into a dark base that matches the YouTube page.

What resolution should my source image be before I upload it here?

At minimum 2048×1152, ideally 2560×1440 or larger. Smaller images get upscaled to fit the 2560×1440 canvas and will look soft on TV. Photos shot on a modern phone (4032×3024) downscale to fit beautifully.

Do my uploads pass through your server?

No. The image is read, scaled, and re-encoded entirely on your device using the canvas API. Nothing leaves the page, which means even unreleased channel branding stays private until you click upload on YouTube itself.
