1500 × 500
A profile header is 1500 × 500, which is an unusually wide 3:1 letterbox — much flatter than anything a camera produces. Cropping a normal photo to it means throwing away most of the height, so the choice of what stays is the whole job. Faces and horizons survive this ratio; tall subjects and anything with important detail at the top or bottom do not.
The second constraint is the avatar. Your profile picture sits over the lower-left of the header and takes a round bite out of it, and on narrow screens the header is cropped in further from the sides. Both push the same conclusion: put the interesting part slightly right of centre and vertically centred, and leave the lower-left corner as background rather than content.
three steps
PNG, JPG or WebP. It is decoded in the page — nothing is uploaded, so nothing waits on a connection.
The crop box is already locked to the 3:1 shape. Drag it over the part that matters and resize it from any corner; the pixel size is shown as you go.
The export is exactly 1500 × 500. JPEG is the sensible pick for photos; PNG for flat graphics and logos.
quick answers
1500 × 500 pixels, a 3:1 ratio. That is what this page crops and exports to, so nothing is stretched or letterboxed on upload.
Over the lower-left of the header, overlapping it. Keep that corner free of anything you need read — a face, a logo or a line of text placed there will be half-covered.
Narrow screens crop the sides of the 3:1 strip rather than shrinking it, so edge content disappears. Centred compositions survive the change; ones with a logo pinned to one end do not.
No. Cropping and resizing happen in your browser and the file never leaves your device.
