Resize Images for Twitter/X — Posts, Headers, and Profile Pictures

Twitter's automatic image cropping is unpredictable. One tweet your photo looks great, the next it chops off the most important part. The only reliable solution is to upload images that already match the platform's expected dimensions. This tool gives you one-click presets for in-stream posts, header banners, and profile pictures, each sized to the exact pixels Twitter displays. Drop your images, pick a format, and download files that will appear exactly as you intend them to on every device.

Output: 1600 x 900 pixels

How It Works

Pick a Twitter/X Format

Choose between in-stream post, header banner, or profile picture. Each preset uses the dimensions that Twitter recommends for sharp, uncropped display.

Drop Your Images

Add one or more photos. The tool scales and center-crops each image to fill the selected Twitter format without leaving empty space or distorting proportions.

Download and Share

Save your correctly sized images and upload them to Twitter/X. Headers will stretch edge to edge, posts will display without cropping, and profile photos will be perfectly circular.

Frequently Asked Questions

What is the recommended image size for Twitter/X posts?

Twitter recommends 1600x900 pixels (16:9 aspect ratio) for in-stream images shared in tweets. This size ensures your photo appears in full without cropping in the timeline. Twitter supports images up to 5 MB for photos and 15 MB for GIFs, but staying close to 1600x900 gives you the most control over what followers see without relying on automatic cropping.

What are the correct Twitter header dimensions?

The Twitter/X header banner should be 1500x500 pixels (3:1 ratio). Keep in mind that the profile photo overlaps the lower-left portion of the header on desktop, and mobile devices may crop slightly differently. Place important visual elements toward the center of the banner to ensure they are visible across all devices and screen sizes.

Why does Twitter crop my images unexpectedly?

Twitter uses an automatic saliency-detection algorithm to decide how to crop images that do not match its preferred aspect ratios. This algorithm tries to find the most interesting part of the image, but it often gets it wrong with text, faces near edges, or unusual compositions. By resizing to the exact recommended dimensions before uploading, you bypass the automatic crop entirely.

What format should I use for Twitter images?

Twitter accepts JPEG, PNG, GIF, and WebP files. For photographs, JPEG provides the best balance of quality and file size. For graphics with text, sharp edges, or transparency, PNG is the better choice. Twitter will re-encode uploaded images regardless, so there is no need to over-optimize — focus on getting the dimensions and composition right.

Are my images uploaded to a server when using this tool?

No. This tool runs entirely in your web browser. The Canvas API handles all resizing and cropping locally on your device. Your original images and the resized output never leave your machine. This is particularly useful for preparing embargoed content, unreleased product photos, or any images you want to keep confidential until you choose to post them.
