Step-by-Step Guide
5 steps · takes under 1 minute
Open the Image Resizer
Go to the Resize tool — browser-based, no upload, works on desktop and mobile.
Upload your banner image
Drop your graphic, photo, or designed banner onto the upload zone. Start with an image at least 2560px wide for best quality.
Turn off aspect ratio lock
Disable 'Maintain aspect ratio' to set width and height independently.
Set Width to 2560 and Height to 1440
Enter 2560 × 1440. This is the full YouTube banner canvas. YouTube's file size limit is 6MB — a 2560×1440 JPG at 85% quality is typically 600KB–1.2MB, well within the limit.
Design within the safe zone
The guaranteed-visible safe zone is the central 1546×423px area. Keep logos, text, and key content within this zone. The outer area is seen on TV only. Avoid placing critical content within 200px of any edge.
100% Private — Zero Uploads
ImgToolkit runs entirely in your browser using the Canvas API. Your images are never sent to a server, never stored in the cloud, and never seen by anyone else. This makes it safe for sensitive documents, client work, medical imagery, and confidential screenshots.
Pro tip
Use 75–85% quality for web images — you get 60–80% smaller files with no visible difference at normal screen sizes.
