How to Crop Video for Instagram
Instagram uses specific aspect ratios for different placements: 9:16 for Reels and Stories, 1:1 or 4:5 for feed posts. FastEdit lets you crop any video to these exact dimensions in your browser. No upload, no watermark, no account. This guide shows you how to get your video sized correctly for each Instagram format.
Steps
01
Open FastEdit
Go to fastedit.net. The editor runs entirely in your browser with no installation or sign-up.
02
Drop your video file
Drag and drop your video onto the editor. MP4, MOV, WebM, and other common formats are supported. Your file stays on your device.
03
Select the Instagram preset
Open the presets menu and choose the Instagram option that matches your target placement: Reels/Stories (9:16, 1080x1920), Feed Post (1:1, 1080x1080), or Feed Portrait (4:5, 1080x1350).
04
Position the crop area
Adjust the crop frame to center your subject within the new aspect ratio. Keep important elements away from the edges, especially the top and bottom where Instagram overlays UI elements.
05
Export as MP4
Select MP4 with H.264 codec for maximum Instagram compatibility. Click Export to download your cropped video, then upload it to Instagram.
Tips
- Instagram Reels and Stories use 9:16 (1080x1920). Feed posts work best at 1:1 (1080x1080) or 4:5 (1080x1350). Use the correct preset for your target placement.
- Keep your subject centered. Instagram crops thumbnails from the center, so edges may be hidden in the feed grid.
- Export as MP4 with H.264 codec. Instagram re-encodes all uploads, but starting with H.264 minimizes double-compression artifacts.
- Keep videos under 60 seconds for Reels and under 60 minutes for feed posts. Shorter content (15-30 seconds) tends to perform better on Reels.
- Avoid placing text near the top or bottom 15% of the frame. Instagram overlays the username, caption, and action buttons in these areas.
