Resize Twitter/X Header — why it works this way
X (formerly Twitter) recommends 1500×500 pixels for profile header images. The header is responsive and can appear at different sizes depending on the viewer's screen, so resizing to the recommended ratio first — with your main subject centered — gives the safest result across devices.
Is my file uploaded? No. Everything happens locally in your browser using the Canvas/File APIs — your file is never sent anywhere.
FAQs
Is my image uploaded anywhere?+
No. Resizing happens entirely in your browser.

No — aspect ratio is preserved.
Why does my header look cropped differently on mobile?+
The header is responsive and X may show a different crop depending on screen size — keeping key content centered helps it survive different crops.
What format is the output?+
JPG.
