How to Crop Video Online Free

Q: What aspect ratio should I use for Instagram?

Instagram Reels and Stories: 9:16 (1080x1920). Instagram Feed: 1:1 (1080x1080) for square posts, or 4:5 (1080x1350) for portrait posts, which takes up more screen space and tends to get more engagement. Landscape 16:9 is supported but displays smaller in the feed.

Q: Can I crop a landscape video to portrait for TikTok?

Yes. Drop your 16:9 video into FastEdit, select the 9:16 preset, position the crop area over your subject, and export. The output is a native portrait video ready for TikTok.

Q: Does cropping reduce video quality?

Cropping itself does not degrade pixel quality, but it reduces resolution because you are keeping a smaller portion of the frame. A 1080p video cropped to 50% of its area yields half the pixels. For best results, start with the highest resolution source available.

Q: Is there a watermark on the exported video?

No. FastEdit adds no watermark, logo, or branding to your exported video. The output is a clean file, free to use however you like.

Need to reframe a 16:9 video for Instagram Stories (9:16), crop a square for social media (1:1), or remove unwanted edges? FastEdit lets you crop video and change aspect ratios directly in your browser with platform presets for Instagram, TikTok, YouTube, and more. No upload, no watermark, completely free.

Steps

Open FastEdit

Go to fastedit.net. No installation or account required. The editor runs in your browser.

Drop your video file

Drag and drop your video onto the editor. Supports MP4, MOV, WebM, MKV, and other formats. The file stays on your device. Nothing is uploaded.

Open the crop tool

Select the crop option in the editor. You will see a crop overlay on your video preview with handles to adjust the crop area.

Choose an aspect ratio or platform preset

Lock to a standard aspect ratio (16:9, 9:16, 1:1, 4:5) or select a platform preset: Instagram Stories/Reels (9:16), TikTok (9:16), YouTube (16:9), Instagram Feed (1:1 or 4:5). The crop area adjusts to match. You can also crop freely without locking.

Position the crop area

Drag the crop rectangle to frame the part of the video you want to keep. For converting landscape to portrait, this step is critical. Position it over your subject.

Export your cropped video

Choose your output format and codec, then click Export. The cropped video downloads directly. The output resolution matches your crop area.

Tips

Instagram Reels and TikTok both use 9:16 (1080x1920). Instagram Feed supports 1:1 (1080x1080) and 4:5 (1080x1350). YouTube uses 16:9 (1920x1080). Use the matching preset to avoid black bars.
When converting 16:9 landscape to 9:16 portrait, you lose the left and right edges. Position the crop carefully over your subject. The center of a landscape shot is not always where the action is.
Cropping reduces resolution. If you start with 1080p and crop to half the width, your output is effectively 540px wide. Start with the highest-resolution source you have.
Combine cropping with other edits: trim to the best segment, adjust speed, add blur to sensitive areas, then export once. FastEdit applies all edits in a single pass.
Use aspect ratio locking to prevent accidentally distorting your crop. Unlock it only when you need a custom, non-standard ratio.
