What size does this tool output?

A 1500 x 500 px image, the size X recommends for profile header photos.

Why is there a guide box in the bottom-left corner?

Your round profile photo sits on top of the header and overlaps roughly that bottom-left region on both desktop and mobile. Keep logos, faces, and text out of it so nothing important gets covered.

Is my photo uploaded to a server?

No. Positioning, zooming, and rendering all happen in your browser with the HTML5 Canvas API. The photo never leaves your device.

Should I download JPG or PNG?

JPG gives a smaller file for a photographic header. PNG is larger but lossless, useful if your header has flat colors or sharp text you want to keep crisp.

What file size does X accept for a header photo?

X accepts JPG or PNG files up to about 5 MB. If your downloaded file is close to that, choose JPG instead of PNG to bring it down.

Choose JPG or PNG, then click "Download Header".

Use cases

Reposition an existing header image so its focal point sits away from the profile-photo corner.
Prepare a header that still reads well once your profile photo overlaps it.
Fit a wide photo into the 1500 x 500 frame without cropping the wrong region.
Preview a header design before uploading it on X.
