Built for selecting the crop area
The crop workflow exports the part of the video inside the selection box. Move the box or resize it from the corners before downloading.
Browser export is not available
This tool needs a modern Chromium browser with WebCodecs support to export MP4 files.
Use Free crop for a custom box or lock the selection to a platform ratio.
Drag the box to move it, or resize from the corners.
How it works
Crop a video in three quick steps
Upload your video
Choose an MP4, WebM, or MOV file from your device. The video is previewed locally in your browser.
Pick the crop frame
Use Free crop or select 9:16, 1:1, 4:5, 16:9, or the original frame, then move and resize the crop box.
Export MP4
Export a cropped MP4 in 720p or 1080p for free, then continue in CaptionBolt, CapCut, YouTube, or another editor.
Crop settings
Choose the exact area to keep
The free crop tool is designed for selecting a specific area of the video before you publish or keep editing.
9:16 vertical crop
Use 9:16 for TikTok, Instagram Reels, and YouTube Shorts, then move the crop box to keep the subject in frame.
Free crop selection
Use Free crop when you want a custom area instead of a platform aspect ratio.
Square and feed crops
Use 1:1 for square posts or 4:5 when you want a taller Instagram feed video.
Widescreen crop
Use 16:9 for YouTube, embeds, decks, and horizontal social posts.
Platform sizes
Crop videos for TikTok, Shorts, Reels, Instagram, and YouTube
Start with the preset that matches your publishing destination, then export a clean MP4.
TikTok, Reels, and Shorts
Choose 9:16 for the vertical full-screen format most short-form platforms expect.
Instagram feed
Choose 4:5 for feed posts or 1:1 when you need a square crop.
YouTube and widescreen
Choose 16:9 when you need a horizontal video for YouTube or website embeds.
Browser notes
A free cropper for quick video fixes
Runs in your browser
The free cropper uses browser-side video APIs and does not send your file to a rendering server.
Best for short clips
Browser export works best with short social clips. Very large videos can be slower or run out of memory.
Manual crop placement
Use the crop box for manual selection. For AI reframing and subject tracking, continue in CaptionBolt.
