About Resize Image for X / Twitter
X (Twitter) timeline images display best at 1200×675 pixels (16:9) — this tool is preset to that box and fits your image without cropping. Drop a photo and download the post-ready result.
Images outside the recommended ratio get center-cropped in the timeline, which can cut off text. Everything runs in your browser; images are never uploaded.
