X (Twitter) Post Resizer — 1200×675
Resize images to X (Twitter) post size 1200×675 (16:9) for maximum timeline impact.
About the X / Twitter Post
This tool outputs the exact X/Twitter timeline post (16:9) dimensions of 1200×675 pixels. Cover mode center-crops to fill the frame edge-to-edge; contain mode fits the whole image with padding. Batch up to 10 images — every one comes out at the precise size the platform expects.
How it works
The tool outputs exactly 1200×675 pixels (16:9), the ratio X renders fully expanded in the timeline — anything else gets cropped in the card view. Cover fitting guarantees edge-to-edge fill; contain preserves the whole image over a pad color when cropping isn't acceptable.
How to use it
Add up to 10 images, pick a fit mode and pad color, process, and download the timeline-ready masters individually or as a ZIP.
Supported formats & limitations
Accepts .jpg, .png and .webp up to 30MB each, 10 per batch. Wide sources fit natively; square and portrait sources either crop (cover) or show side bars (contain) — choose per image if the batch mixes shapes.
Common use cases
Announcement images, blog share cards, product launches and thread visuals — anywhere the preview crop in the timeline determines whether people tap through.
Frequently asked questions
What size is x / twitter post?
1200×675 pixels — this tool outputs exactly that size. Cover mode center-crops your image to fill the frame; contain mode keeps the whole image visible and pads the difference.
What is 1200×675 in cm or inches?
Social platforms define sizes in pixels only, because physical size depends on the screen. For reference: printed at 300 DPI, 1200×675 px measures about 10.2×5.7 cm (4.00×2.25 in).
Cover or contain?
Cover fills the frame completely (crops edges); contain shows the full image with padded bars. Use cover for photos, contain for logos or graphics you don't want cropped.
Can I resize several x / twitter post images at once?
Yes — drop up to 10 files and every one comes out at exactly 1200×675 px. Results can be downloaded individually or as a single ZIP.
