X / Twitter Header Resizer
Build a clean X header that works across desktop and mobile. The 3:1 preset keeps the banner wide while giving you crop control.
Your image stays on this device. Nothing is uploaded.

JPG, PNG, WebP or SVG. You can also paste an image with Ctrl+V.
Pick a starting size; the preview updates as you work.
The details that matter
These are the dimensions most likely to give you a clean upload. The workspace starts here, but you can still make the crop your own.
A simple three-step workflow
- 1Drop your banner image into the 3:1 workspace.
- 2Position the focal point away from the profile-photo area.
- 3Export a crisp JPG or WebP and check it on both desktop and mobile.
- Keep logos and faces toward the center; profile photos and responsive cropping can cover the lower-left area.
- Use a subtle background so profile text remains legible over the banner.
Common questions
What size should a X header banner image be?
For the most predictable result, start with 1500 × 500 px. The preset on this page applies those pixels for you.
Will my image be uploaded?
No. TulipTools draws and exports your image in your browser. The file never travels to a server.
Which formats can I export?
You can export JPG, PNG, or WebP. WebP is usually the smallest choice for websites and social uploads.
Can I keep the whole photo visible?
Yes. Switch the fit mode to Contain and choose a solid or blurred background so the full image stays in frame.
