X (Twitter) Image Sizes That Actually Matter
X uses aggressive center-cropping on images that don't match its preferred ratios. Uploading the wrong dimensions means your key message or subject gets cut off in the timeline.
Post images (16:9 at 1200x675px) are the only format that displays fully in the timeline without any cropping. This is your safest bet for images with text or important edge content. Headers (3:1 at 1500x500px) are your profile banner — keep important elements in the center 60% since mobile crops the edges. Card images (1.91:1 at 1200x628px) control how your links look when shared on X — set them via your Open Graph meta tags.
This free X image resizer handles all three formats. For the complete specification including video dimensions, see our complete X (Twitter) image sizes guide. Want to know when to post? Check our best time to post on X tool.
X (Twitter) Image Resizer FAQ
What image sizes does this tool create?
This tool creates three X (Twitter)-optimized sizes: Post Image (1200x675px) in 16:9 landscape for timeline posts that display without cropping, Header / Banner (1500x500px) in 3:1 for your profile banner, and Card Image (1200x628px) in 1.91:1 for link preview images.
What file formats are supported?
You can upload JPEG, PNG, or WebP images. All exports are saved as high-quality PNG files. X supports JPEG, PNG, GIF, and WebP natively.
Is there a file size limit?
Yes, the maximum upload size is 10MB. This covers most photos and graphics. X itself has a 5MB limit for image uploads, so our exports will always be within platform limits.
How does the cropping work?
The tool uses center-crop to automatically resize your image. It calculates the best area to keep based on your selected dimensions and crops from the center, preserving the most important part of your image.
Is this tool completely free?
Yes, 100% free with no registration required. There are no watermarks, no usage limits, and no hidden fees. Just upload, resize, and download.
Will my images be saved or stored?
No. All image processing happens entirely in your browser. Your images are never uploaded to any server. They are processed instantly on your device and discarded when you close the page.
Which X image type should I choose?
Choose Post Image (16:9) for tweets with images — this is the only ratio that displays fully in the timeline without any cropping. Use Header / Banner (3:1) to update your profile banner — keep key elements in the center 60% since mobile crops the edges. Use Card Image (1.91:1) to create link preview images for your website's Open Graph tags.
