Twitter / X Image Size Guide 2026: Posts, Profile, and Header

File Size Tips for Twitter

Twitter aggressively re-compresses images — especially on mobile. Compress to 500KB before uploading — Twitter will compress further but starting with a high-quality source produces a better result. Use PNG for graphics with text; JPG for photographs.
