Crop Video to 9:16 Vertical for TikTok & Reels — Free, No App

TikTok, Instagram Reels, and YouTube Shorts all demand 9:16 vertical video — but most footage is shot wide. Cropping a 16:9 landscape clip down to 9:16 portrait without re-encoding in a full editor used to mean learning Premiere or CapCut. Now you can do it in your browser in seconds, no app, no watermark, no account.

Why 9:16 Matters for TikTok, Reels & Shorts

Short-form platforms are built for vertical scrolling on a phone. A 9:16 video fills the entire screen — anything else shows black bars or gets auto-cropped badly by the platform.

• TikTok: Recommended 1080×1920, up to 60s (or 3 min for longer posts)
• Instagram Reels: 1080×1920, max 90s
• YouTube Shorts: 1080×1920, max 60s

If you post a 16:9 clip as-is, the platform may letterbox it with blurry zoomed bars — or crop it automatically in an unflattering way. Manual cropping gives you full control over what stays in frame.

How to Crop Video to 9:16 — Step by Step

Using the free browser-based video cropper:

1. Upload your video (MP4, MOV, WebM, AVI, or MKV)
2. Select the 9:16 preset from the aspect ratio buttons
3. Drag the crop box to center on your subject
4. Click Crop Video
5. Download the result as an MP4

The tool runs entirely in your browser — no upload to any server, no account required, no watermark added. Processing time is typically under 30 seconds for clips up to a few minutes.

Choosing What to Keep in Frame When Cropping

The 9:16 crop cuts roughly half the width of a standard 16:9 video. Before cropping, decide:

• Face / speaker: Center the crop on the speaker's face. Avoid cutting off the top of the head.
• Action / sport footage: Follow the main action — if a person is moving left, bias the crop left.
• Landscape / B-roll: Pick the most interesting vertical slice. A wide mountain range might crop to a single dramatic peak.
• Text / graphics on screen: Make sure any overlaid text stays inside the crop box before confirming.

The crop tool lets you drag and reposition the box freely before committing — take a moment to preview the framing.

Does Cropping a Video Reduce Quality?

Yes and no. Cropping removes pixels from the sides — it doesn't lower the resolution of what remains. If your original is 1080p and you crop to 9:16, the output is still crisp at whatever resolution fits inside the crop box.

What can affect quality:

• Source resolution: A 720p original cropped to 9:16 will be lower resolution than a 4K original cropped the same way.
• Re-encoding: Any re-encode introduces some compression. The browser tool minimizes this with high-quality settings.

For TikTok and Reels, 1080×1920 output is ideal. If your source is at least 1080p, the cropped result will look great on any phone screen.
