Why there's no upload step
Facebook recommends 820×312 pixels for cover photos (a wide banner shape). Uploading the wrong ratio often gets important parts of the image cropped out by Facebook's own display logic — resizing to the exact ratio first keeps you in control of the framing.
Is my image uploaded anywhere?+
No. Resizing happens entirely in your browser.
Will my image be stretched to fit the banner shape?+
No — aspect ratio is preserved, so a non-matching image fits inside the 820x312 box rather than being distorted.
Does this work for the mobile cover photo crop too?+
Facebook shows a slightly different crop on mobile vs desktop — keep your main subject centered for the safest result across both.
What format is the output?+
JPG.
