X (Twitter) Image Resizer

Resize a photo to X's 1600 × 900 in-timeline post size — free, instant, entirely on your device.

How to resize a photo for X

Drop a photo into the box above and it's automatically center-cropped to a 16:9 ratio and scaled to 1600 × 900 pixels — the size X displays uncropped in the timeline — then offered for download.

For example, a tall portrait photo will lose some of its top and bottom when cropped to this wide ratio, so it's worth checking the preview thumbnail before posting to make sure the important part of the shot is still framed well.

Why this ratio avoids awkward cropping

X (formerly Twitter) crops images that don't match its expected aspect ratio when displaying them in the timeline preview, sometimes cutting off faces or important details. Pre-cropping to 16:9 at 1600×900 matches what X actually uses, so what you see here is what followers will see, without unexpected cropping.

Avoiding the timeline crop

X's timeline displays most images at a wide landscape crop by default, which means a tall or square photo often gets its top and bottom trimmed off in the feed preview — viewers only see the full image if they tap to expand it. Resizing to the platform's preferred landscape ratio before posting keeps the important part of your image visible without anyone needing to click through.

This matters most for images with text or a face near the top or bottom edge — a quote graphic or a screenshot, for instance — since those are exactly the elements a timeline crop is most likely to cut into if the image wasn't sized correctly beforehand.

Checking the crop before you post

Because the timeline crop happens after upload, it's worth previewing how your resized image looks at the platform's landscape ratio specifically, rather than assuming the original composition will survive untouched — a face or headline positioned near the very top or bottom of a taller original image is the most common casualty of that automatic crop.

Resizing happens entirely in your browser through the Canvas API, so you can adjust and re-check the composition as many times as you like before saving the final version to post.
