How to use this tool

4 steps · ~30 seconds

Each step is a single action — no setup, no sign-up. Outputs are client-side; nothing is uploaded.

Step 01

Upload a 2560×1440 source

Drag-and-drop or click the upload zone. YouTube recommends 2560×1440 for best quality; 2048×1152 is the minimum.

Step 02

Position via X / Y / Zoom

Use the numeric inputs (or the range sliders below them) to centre your subject inside the 1546×423 mobile safe zone — that's the universal area visible across every device.

Step 03

Pick format

JPG keeps the file size small (under 6 MB easily). PNG is lossless but exports near the 6 MB cap on large banners.

Step 04

Download all 4 crops

TV, Desktop, Tablet, Mobile — one button each. Upload them to YouTube Studio under Customisation → Branding → Banner image.

FAQ · methodology & caveats

Frequently asked.

Calculator outputs are estimates. Each Q below names the source data and the assumptions baked in.

Why does YouTube need so many banner crops?

YouTube serves your channel art at different sizes depending on device — TV apps render the full 2560×1440, desktop/tablet/mobile crop a centered horizontal band. The mobile crop (1546×423) is the smallest, so it acts as the universal safe zone: anything outside that band gets clipped on at least one device.

What's the maximum file size?

YouTube caps banner uploads at 6 MB (verified May 2026). The tool surfaces an inline byte counter per crop and flags any export that crosses the cap. Switch to JPG format or simplify the source to fit under 6 MB.

My source is 1920×1080 — will it work?

No. YouTube's documented minimum is 2048×1152. The tool warns you if your source is below that. Re-export at 2560×1440 from your design tool for best quality across all four crops.

What does the brand tint overlay do?

Optional colour wash over the whole crop. Useful when your source photo is too busy and you want to unify it under a single brand colour. Tint opacity is adjustable from 0–100%.

Is my source image uploaded to your server?

No. All resizing happens in your browser via Canvas API. The source never leaves your device — no upload, no logging, no analytics on file contents.
