Facebook image resizer

851 × 315 pixels. That is the file Facebook's help centre asks a Page owner to upload, and it is what this tool exports. Facebook also says a cover loads fastest as an sRGB JPG under 100 kilobytes, which is advice rather than a limit — the size of your file is printed under it here, and the quality slider is how you bring it down.

Because Facebook takes one file and shows it at two shapes. Its help page says the cover displays at 16:9 on a computer and 2.4:1 on a phone, both full bleed, which means the frame is filled and whatever hangs over the edge is cut. Your 851 × 315 file is wider than either frame, so both keep its full height and take a slice of its width: 560 pixels across on a computer, 756 on a phone. The computer is the tighter of the two, so 560 × 315 is the part seen everywhere.

Inside the 560 × 315 band this tool draws on your cover, and away from the bottom left, where Facebook lays your profile picture over the cover — by about 40 pixels on a phone, says the same help page. Facebook does not publish which part of your file it keeps, so the band here is drawn down the middle. Treat its size as the fact and its position as a starting point: move the crop here, and drag the cover again once it is on Facebook, until what matters is inside it.

1440 × 1800 pixels, in the 4:5 shape. Worth knowing where that comes from: Facebook publishes no size of its own for an ordinary photo post, so this is the figure from Meta's ads guide, which is written for advertisers. It is still the right shape to aim at — 4:5 is the tallest a photo runs in the feed, so it fills more of a phone screen than a square does.

JPG for photographs, PNG when there is a logo or text with hard edges. Meta's ads guide names JPG and PNG, so those are the safe choices. WebP gives you a smaller file at the same quality and Facebook accepts it, but if anything downstream chokes on a picture, JPG is the one to fall back to.

320 × 320 pixels, says Facebook's help centre, and it must be at least 400 wide and 150 tall to be accepted at all. It is cropped to a circle, and shown at 176 pixels across on a computer and 196 on a phone — so anything near the corners of your square is cut, and small text will not be readable at that size.

The one your page names as its og:image, and Meta's sharing documentation asks for 1200 × 630 pixels, under 8 MB, as close to 1.91:1 as you can get. This tool exports that size. Putting it on your website is a job for whoever edits the site — resizing it here does not change what Facebook reads.

Not as its own size. Facebook's help page for adding an event cover photo gives no pixel size at all, and a made-up number would be worse than none. The closest published size is the link preview, 1200 × 630 at 1.91:1, which is a reasonable shape for an event cover too.

Free, with no account, no card and no daily limit, and your picture is never uploaded. Your browser opens the file, resizes it on your own device, and hands you the result. Nothing is sent to Soyla or anyone else and nothing is stored, so a photo of your shop, your team or your customers is safe to use. Close the tab and it is gone.
