Resize an image for X (Twitter) profile picture: 400 × 400 px
Drop a photo and get it at exactly 400 × 400 pixels, the X (Twitter) profile picture size (1:1 ratio). The image is scaled to fill the frame and centre-cropped, so nothing is stretched. Cropped to a circle.
How to use the X (Twitter) profile picture resizer
- Add one or more photos (JPG, PNG, WebP or iPhone HEIC).
- The size is preset to 400 × 400; adjust only if X (Twitter) changes its spec.
- Click Resize. The photo is scaled to cover the frame and cropped from the centre.
- Download and upload to X (Twitter).
X (Twitter) profile picture size in 2026
The recommended X (Twitter) profile picture image is 400 × 400 px, an aspect ratio of 1:1. Cropped to a circle. X shows single images at 16:9 in the timeline and crops others to that ratio in previews, so a 1600 × 900 image is displayed without cropping. Header images are cropped on mobile at the top and bottom; profile pictures are round.
How this tool fits your photo
Most photos are 4:3 or 3:2, not 1:1. Rather than stretching, this tool scales the photo until it covers the 400 × 400 frame and then crops equally from the edges that overflow. For a portrait photo going into a landscape slot, that means the top and bottom are trimmed; for a landscape photo going into a portrait slot, the sides. If the subject is off-centre, crop it roughly first in your phone's editor, then use this tool for the exact pixels. Images smaller than 400 × 400 are enlarged, which softens them slightly; start from the largest original you have.
Format and file size
JPG, PNG or WebP; GIF up to 15 MB. 5 MB for photos on web. Output here keeps your input format (JPG stays JPG at quality 90, PNG stays PNG). If the result is over the platform's limit, run it through the image compressor with a target size.
