FAQ

What size is an Instagram post?

1080×1080 for square and 1080×1350 for portrait (4:5), which takes up more of the feed. Stories and reels: 1080×1920.

And a YouTube thumbnail?

1280×720 pixels (16:9).

What does "Fit whole" do?

It keeps the whole photo uncropped and fills the gaps with a blurred copy of it, or white or black. Perfect for putting a landscape photo in a story.

Is quality lost?

It exports a high-quality JPG at the exact size each network wants, so the network recompresses it less.

Is my photo uploaded?

No. Everything happens in your browser.
