Resize Image for Twitter/X Profile Picture (400x400)

Twitter (now X) displays profile pictures as circles at multiple sizes depending on context. In the feed, profile pictures appear at approximately 48x48 pixels. On profile pages, they display at 200x200 pixels. In search results and notifications, they appear at 32x32 pixels.

Upload at 400x400 pixels to ensure sharp rendering at all display sizes, especially on high-DPI (Retina) screens where the effective display resolution is doubled. The circular crop means content near the edges will be cut — ensure your face, logo, or key graphic is centered with some padding around the edges.

Twitter applies its own compression to all uploaded images. Profile pictures are re-encoded as JPEG at approximately 80-85% quality and served in WebP to supporting browsers. This means starting with a high-quality 400x400 image is important — Twitter's compression has more to work with and produces a sharper result.

For logos and graphics with sharp edges, upload as PNG. Twitter will convert it to JPEG internally, but starting from a lossless PNG gives the JPEG encoder better source data than re-encoding an already-compressed JPEG. For photographs, JPG works fine.

While this tool configures for profile pictures (400x400), the Twitter/X header banner has different dimensions: 1500x500 pixels (3:1 ratio). The header is cropped differently on mobile vs desktop — the center is always visible, but the top and bottom can be cut on mobile devices.

For your header, keep important content within the center 1500x420 pixel area. Profile picture placement overlaps the header at the lower-left corner, so avoid placing key elements there. The header supports JPG or PNG under 5MB.
