Resize Image to 400×400 — Twitter/X Profile Picture & Steam Avatar
Resize to 400×400 pixels for Twitter/X profile avatars, Steam community icons, and circular profile pictures.
Resize Options
Upload images with drag & drop, choose from preset sizes or enter custom dimensions. High-quality output, instant preview, and free to use.
Where is 400×400 Commonly Used?
400×400 pixels is the officially recommended size for Twitter/X account profile photos and Steam community gaming avatars. The platform crops the image into a circular frame, so key facial features should remain centered.
Best Practices for 400×400 Images
Use PNG if your avatar features flat vector illustrations or crisp logos; use JPEG/WebP for real-life portraits and headshots. Once resized, you can host your picture permanently on our Free Image Hosting to get a direct CDN URL, or convert between formats using our Image Converters.
