# YouTube banner resizer

Canonical: https://postmesh.app/tools/youtube-banner-resizer

Drop in an image to crop and resize it to YouTube’s banner size. Your image stays on your device.

## How it works

These are export canvas presets. Check the linked platform guidance for current upload requirements and cropping. Pick a size, move the crop to frame what matters, and download a file at exactly those dimensions.

Resizing runs in your browser, so the image is never uploaded to PostMesh.

## Steps

1. Choose an image.

2. Pick a size and adjust the crop sliders.

3. Download the resized file.

## Sizes in this tool

| Preset | Pixels | Shape |
| --- | --- | --- |
| Channel banner | 2,560 × 1,440 | 16:9 |
| Profile picture | 800 × 800 | 1:1 |

Presets are export sizes that suit each spot. Where a network sets a minimum or a file limit, its own help page has the final word: the tool links to it.

## Getting a clean crop

- Start from the largest original you have: enlarging a small image can’t add detail.
- Keep faces and text away from the edges, where profile circles and phone screens crop.
- Download a PNG for logos and text, a JPEG for photos.

A JPEG for photos, or a PNG if your image has transparency.
