How to Resize Video for Instagram
Resize Videos for Reels, Stories, and Posts
Choose Video Size
Select vertical 9:16 for Reels and Stories, square 1:1 or portrait 4:5 for feed posts, or horizontal 16:9. Flixier shows the output dimensions before you resize, so you can check that you’ve chosen the right format.
Control the Crop
Choose Crop to fill, then drag the handles to decide which part of your video stays visible. You can also enter the exact position, width, and height, and if your footage was recorded sideways, rotate your video for Instagram before adjusting the crop.
Frame Your Video
If you don’t want to crop anything out, choose the option that keeps the whole video visible. Extra space is added around it to match the selected format.
No Upload Needed
Your video is processed directly on your device instead of being uploaded to Flixier’s servers. This means there’s no upload to wait for and no app to install before you start resizing.

How do I resize a video for Instagram?
Simply upload your video and choose vertical, square, horizontal, or portrait. Decide whether you want the video to fill the frame or remain fully visible, then adjust the crop if needed. Check the output dimensions, click Resize, and save the finished version to your device.
What size should a video be for Instagram?
Instagram Reels and Stories use a vertical 9:16 format. Feed videos can use square 1:1 or portrait 4:5, while horizontal 16:9 is also available. Choose the preset that matches where you plan to post the video.
Can I turn a landscape video into a reel without cropping?
Yes, simply choose the vertical 9:16 preset, then decide how the landscape video should fit. Fill the frame and reposition the crop around your subject, or keep the whole shot visible if you don’t want anything removed from the sides of the original recording.
Will resizing my Instagram video crop part of it?
Only if you choose to fill the frame. Because the new format may have a different shape, some content around the edges can be removed. Drag the crop handles to control what stays visible, or choose the option that keeps the entire original shot inside the new frame.
Is my video uploaded to Flixier’s servers?
No, because the Instagram video resizer processes your file locally using your device, so the video does not need to be uploaded to Flixier’s servers. This removes the initial upload wait and means you can start resizing without installing an app or creating a full editing project.
