What a YouTube banner maker does and why it matters

YouTube channel art is one image that is displayed at very different sizes on phones, tablets, desktops, and TVs. YouTube crops the same 2560 x 1440 upload differently on each device, showing only a small central strip on mobile but a much wider area on TV. A banner maker helps you size the full image correctly and, crucially, keep your channel name and logo inside the region that is visible everywhere.

imgbox does this in the browser with Canvas and WebAssembly. Your image is processed on your own device and never uploaded, there is no watermark, and there is no account or limit. You get precise control over the crop and safe zone without handing your artwork to a third party.

• Sizes your image to YouTube's full 2560 x 1440 canvas
• Keeps key elements inside the safe area visible on all devices
• No upload, no watermark, no account, no limits
• Works offline in the browser once loaded

Exact YouTube banner dimensions and the safe area

The recommended upload size for YouTube channel art is 2560 x 1440 pixels, a 16:9 image. However, only a central region is guaranteed to show on every device: the safe area for text and logos is 1235 x 338 pixels, centered in the middle of the banner. Anything important placed outside that central strip risks being cropped on smaller screens.

YouTube also caps the file at a maximum of 6 MB, so export a well-compressed JPG or PNG. Designing on the full 2560 x 1440 canvas while keeping your channel name, tagline, and logo inside the 1235 x 338 safe area is the key to a banner that looks right everywhere.

• Full banner canvas: 2560 x 1440 px (16:9)
• Safe area for text and logo: 1235 x 338 px, centered
• Maximum file size: 6 MB
• Minimum recommended upload: 2048 x 1152 px
• Mobile shows only the central strip; TV shows the widest area

YouTube banner dimensions for every device

YouTube shows a different crop of the same image on every device. You upload one 2560 × 1440 file, and YouTube trims it down — most aggressively on mobile, where only the central 1546 × 423 area survives.

That central area is the safe zone. Anything outside it — text, logos, social handles — will be cut off for some of your viewers.

How to design inside the safe zones

Think of the banner in two layers. The full 2560 x 1440 canvas is background: colors, patterns, or imagery that can safely extend to the edges and be cropped on smaller screens without losing meaning. The central 1235 x 338 safe area is where you place everything that must be seen, such as your channel name, tagline, upload schedule, and logo.

Because the visible area shrinks on mobile, keep your most important element, usually the channel name and logo, tightly centered. Use the background layer for atmosphere and the safe area for the message, and the banner will read clearly on a phone and a TV alike.

• Put channel name, tagline, and logo inside the 1235 x 338 safe area
• Let backgrounds and imagery bleed to the full 2560 x 1440 edges
• Center the most important element so mobile viewers still see it
• Avoid placing text near the outer edges where it gets cropped
• Keep the safe-area text large and high-contrast for small screens

Common use cases

A correctly sized banner sets the tone for a channel and reinforces its brand across every device. Creators of all sizes use one well-built banner to present their name, niche, and upload schedule at a glance.

• Launching or rebranding a YouTube channel
• Showing an upload schedule or tagline in the banner
• Keeping a consistent look across banner, thumbnails, and logo
• Updating channel art for a series, season, or campaign
• Cropping a wide graphic down to YouTube's exact 16:9 spec

Why build your banner in the browser

Design tools that live online usually upload your artwork, add watermarks on free tiers, or require an account. imgbox keeps your image on your device, adds no watermark, and asks for nothing, so you can crop to spec and export privately and for free.

You also get exact control over the safe zone. Instead of guessing whether your channel name will survive YouTube's device cropping, you position it inside the marked safe area and export at the full 2560 x 1440 resolution, confident it will display correctly everywhere.
