FAQ

How do I keep the aspect ratio?

Use “Fit inside” and enter just a width or just a height (or both as maximums). The other side is calculated automatically so nothing gets squashed.

What does “Do not enlarge” do?

Images that are already smaller than your target are left at their original size, so small images don't become blurry.

Which size is best for link previews?

1200×630 is the standard Open Graph size used by Facebook, LinkedIn, Slack and X. Pick it from the presets with “Crop to fill”.
