Frequently asked questions

What size should an Instagram video be?

Reels and Stories are 1080×1920 (9:16), the portrait feed is 1080×1350 (4:5), square posts are 1080×1080 and landscape is 1080×566 (1.91:1). This tool exports each one exactly.

Is my video uploaded anywhere?

No. The resize runs entirely in your browser, on your device. Your video is never sent to a server.

Contain or fill for Instagram?

“Contain” keeps the whole frame and adds bars; “fill” crops to cover the format edge to edge. For Reels, fill usually looks best; to keep everything visible, choose contain.

Is there a watermark or a fee?

No watermark, no account, no fee. The output is a clean MP4 ready to upload to Instagram.

Can I resize a video for Instagram Reels specifically?

Yes. Pick the Reels/Story preset (9:16, 1080×1920). It's the fastest way to resize video for Reels or IG Stories without cropping out anything important.
