Twitch Banner Size Resizer

A Twitch channel uses three kinds of artwork besides the avatar: the profile banner across the top of your channel, the video player banner shown while you are offline, and the panels under the stream. Twitch's settings recommend 1200 × 480 pixels for the profile banner and a 16:9 image such as 1920 × 1080 for the offline banner, each up to 10 MB, and panels are shown 320 pixels wide. This resizer crops or fits your art to those sizes and keeps the files under the limit.

How to use this tool

1. Choose your artwork (several files are fine).
2. Pick the profile banner, offline banner or panel size.
3. Crop to fill and set the position, or show the whole image on a colour or blurred background.
4. For the offline banner, check the guide: player controls cover the bottom strip.
5. Download and upload under Creator Dashboard → Settings → Channel → Brand (banners) or under your About panels.

Formula

scale = max(target width ÷ width, target height ÷ height) × zoom · JPG quality steps down by 6 points until the file is under the limit

Banners are kept under 10 MB unless you set your own maximum. Panels are 320 px wide; 320 × 160 is a common height, and you can stack text into the image itself.

Example

A 3840 × 2160 gameplay screenshot used as the offline banner keeps its full frame and is scaled by 1920/3840 = 0.5 to 1920 × 1080. Used as the profile banner (1200 × 480) the same image keeps a 3840 × 1536 window, the middle 71% of its height.
