YouTube banner resizer. See the crop first.

Drop any image, export at the exact 2560×1440 YouTube spec, and preview exactly what mobile, desktop, and TV viewers will see before you upload, the safe zone included.

Runs entirely in your browser using HTML5 Canvas. Your image never leaves your device. How we know.

The tightest crop there is, centered on the canvas. This is YouTube's official safe zone: the only area guaranteed visible on every device, including the mobile app.

One image, three crops

Your banner is one file. YouTube shows three of them.

You upload a single 2560×1440 image, and YouTube crops it differently depending on where someone views your channel. TV shows everything. Desktop shows a wide band. Mobile, where most of your traffic actually is, shows only the centered core. Design for the tightest crop and every other surface takes care of itself.

TV

2560×1440

The full canvas, uncropped. What a connected-TV app shows, and the only surface where your full design is ever seen.

Desktop

2560×423

Full width, a short vertical band. What youtube.com shows in a browser on a computer.

Why this tool exists

Other resizers guess. This one shows you.

Most banner tools export a flat 2560×1440 file and leave you to imagine what mobile crops away. A few offer a separate safe-zone preview you have to switch to. This tool puts the live preview and the export in the same canvas, so you catch a clipped logo before you upload, not after.

01

Live safe-zone preview

Flip between TV, desktop, and mobile and watch exactly what gets masked out on each, on the same image you are about to export.

02

Browser-based

Pure HTML5 Canvas. No backend, no server-side processing. Verifiable in your DevTools Network tab, zero outbound requests with image data.

03

Auto-fits under 6 MB

JPG quality steps down progressively until your file passes YouTube's banner upload cap. No more "file too large" errors.

04

Works offline

Once the page is loaded, no internet needed. Drop, preview, download, repeat, the whole loop runs locally.

Frequently asked

Banner sizing, answered.

2560×1440 pixels, 16:9. That is the recommended size YouTube itself gives creators, and it is what this tool always exports to. The minimum YouTube will accept is 2048×1152, but starting from the minimum gives you no room for the safe zone math to breathe, so 2560×1440 is the size to design and upload at.
Because YouTube crops your one banner image differently per surface, and mobile shows by far the smallest slice. The mobile app and mobile web only show the centered 1546×423 pixel "safe zone," desktop shows a wider 2560×423 band, and only TV shows your full 2560×1440 canvas. If your logo or text sits outside that centered 1546×423 box, most of your visitors will never see it. Use the Mobile tab above to check before you upload.
No, and that is a common misconception. You upload exactly one 2560×1440 image. YouTube's own interface does the cropping per device automatically. The device tabs on this tool are a preview, showing you what each surface will crop to, so you can move your logo and text inside the safe zone before you upload, not a set of separate exports.
Up to 6MB, in JPG, PNG, GIF, or BMP. That is a higher cap than the 2MB YouTube enforces on video thumbnails, so banners have more headroom for detail. This tool defaults to JPG and automatically steps the quality down until your file clears 6MB, so a "file too large" rejection should not happen if you export from here.
No. The entire resize and preview runs in your browser using HTML5 Canvas. Nothing is uploaded, logged, or stored. Open your browser's DevTools Network tab while using the tool and you will see zero outbound requests carrying image data. A draft banner or an unreleased channel rebrand stays on your device the entire time.
JPG for photographic banners (real photos, gradients, textured backgrounds). PNG for flat graphic designs with sharp text or logos, since PNG does not introduce compression artifacts around hard edges. Most channel banners are graphic-led, so if your logo text looks slightly soft after exporting as JPG, switch to PNG.
Your channel profile picture should be 800×800 pixels, square, under 2MB, displayed as a circle. A video watermark (the small logo that appears on your videos) needs a minimum of 150×150 pixels, also square, under 1MB. Neither uses the banner's safe zone rules since both are simple squares with no device cropping to worry about.
No. YouTube removed clickable banner links in 2023. Links now live as up to 14 entries directly under your channel description, next to your channel name, not on the banner image itself. Design your banner as a pure visual (name, niche, upload schedule) and put your actual links in the About section instead.
