The Facebook cover photo is 820×312 pixels — the wide banner across the top of a Facebook page on desktop. The tool above is already set to those dimensions, so you can drop an image in and get a correctly sized file back immediately.
Uploading an image at the wrong dimensions is what causes the awkward crops and soft, over-compressed results you see on badly set up profiles. Platforms re-encode whatever you give them; handing them a file that already matches their target means their encoder has far less work to do, and the version your audience sees stays sharp.
Output is WebP by default for the smallest file. If the platform you are uploading to rejects WebP, switch the format to JPEG — the dimensions stay exactly the same either way.

Frequently asked questions
Are my images uploaded to a server?
No. The conversion runs inside your browser using WebAssembly, so the image data never leaves your device. That also means there is no queue, no account, and no file size cap imposed by a server.
What is the correct Facebook cover photo size?
820×312 pixels. Supplying an image at exactly these dimensions avoids the platform rescaling it, which is what usually softens the result.
My image is a different shape — what happens?
It is scaled proportionally to fit inside 820×312 rather than being stretched. If you need it to fill the frame exactly, turn off "keep aspect ratio", though be aware that will distort the image if the source ratio differs.
Can I convert several images at once?
Yes. Drop in as many files as you like — or a whole folder — and they are processed in parallel across your CPU cores. When they finish you can download them individually or grab everything as a single ZIP.
