This tool returns the exact pixel dimensions and export settings for every Twitch channel image — profile picture, profile banner, and the offline video screen. Each asset has its own recommended size, aspect ratio and crop behaviour, and getting them right keeps your channel looking sharp instead of stretched or pixelated.
The three main Twitch channel images
Twitch uses three distinct image assets for channel branding, and they behave very differently from one another:
Profile picture
Upload a square image at 256×256 pixels (200×200 minimum), under 10 MB. Twitch immediately masks it into a circle — the corners of your square are completely hidden. This means anything important (a face, a logo, a character) needs to fit inside the circular centre. Twitch Partners and Affiliates can upload animated GIFs as their profile picture.
The profile picture appears in chat, on the channel page header, in search results, in directory listings, and in any notification the user receives. It is the single most-seen piece of your channel branding.
Profile banner
The banner across the top of your channel page is 1200×480 pixels (a 2.5:1 ratio), under 10 MB in JPG, PNG or GIF. The profile picture overlaps the lower-left of this banner, so keep critical text and logos clear of that area. Think of the right half of the banner as the safe zone. Many streamers use the banner to communicate their streaming schedule, content category and social handles.
Offline video banner
When you are not live, the player frame shows this static image at 1920×1080 pixels (16:9), matching the player’s natural dimensions. JPG or PNG only (no GIF), under 10 MB. This is your storefront during off-hours — a well-designed offline banner typically shows the next stream date or a highlight reel thumbnail that encourages a follow.
How it works
Pick an asset and the tool reads its spec from a built-in table of Twitch’s recommended dimensions: the upload size, aspect ratio, accepted formats and file-size cap. The tip line for each asset reminds you how Twitch crops or masks it, so you can keep key content inside the area that actually stays visible.
Tips
- Centre your logo or face in the profile picture; the circular mask hides the corners of a square upload.
- Design the profile banner so important text sits in the right-centre — the strip is wide and short, and the avatar sits over the lower-left.
- Use the offline banner to advertise your schedule or next stream date; it is the first thing visitors see when you are not live.
- Export logos and text as PNG for crisp edges; photographic backgrounds work fine as JPG to stay under the 10 MB cap.
