Questions people ask

Which sizes does Instagram use?

Feed posts show best at 4:5, which is 1080 by 1350 pixels. Reels and Stories are 9:16, which is 1080 by 1920. Square 1:1 still works in the feed but takes less space on screen.

Can I make a Reel from a landscape video?

Yes. Choose 9:16 and drag the frame to the part of the picture you want to keep. Zoom in a little if the subject is small.

Does cropping reduce quality?

The pixels inside the frame are kept at their original size and re-encoded once at high quality. Instagram compresses the upload again, so start from a clean file.

Do you upload my video?

No. The tool runs entirely in your browser. Your file stays on your device until you post it yourself.

Which browsers are supported?

Chrome, Edge and Safari 17 or newer on desktop and Android. Firefox does not support the video APIs the tool needs yet.
