What This Tool Does
This tool resizes images to the dimensions Twitter (now X) uses for tweets, headers, profile pictures, and cards. Choose a preset, preview the result, and download the correctly sized image.
Twitter crops images in the feed to specific aspect ratios. Images that are not sized correctly may lose important details when displayed. Resizing before uploading ensures your visuals appear exactly as you intend.
When to Use This Tool
- Preparing an image for a tweet that displays without cropping.
- Updating your Twitter header or profile picture.
- Creating images for Twitter Cards that display correctly in link previews.
- Resizing screenshots or graphics for sharing in a tweet thread.
- Preparing visuals for a Twitter ad campaign.
How to Use This Tool
- Upload your image using the upload area.
- Select the appropriate Twitter preset (e.g. In-Feed Image, Header, Profile).
- Choose Fit, Fill, or Stretch to control how the image is resized.
- Preview the output and make adjustments if needed.
- Download and use the resized image in your tweet or profile.
Best Practices for Images
- X may crop tall or wide images in the timeline preview, and the crop can differ between the website and the app. Preview both views before posting.
- Keep key subjects in the center of the image to avoid losing them to automatic cropping.
- For header images, place text and logos in the center since edges are cropped on smaller screens.
- Use PNG for graphics with text and JPEG for photographs to balance quality and file size.
- Test your image on both desktop and the mobile app before posting.
