Crop Video online
Every platform wants a different shape. A video shot in landscape gets pillarboxed into grey bars on a phone feed; a vertical clip gets the same treatment on a widescreen. Cropping fixes that properly — it cuts the frame down to the shape you need and fills it, rather than shrinking the picture and padding the sides. Pick a ratio, choose which part of the frame to keep, and the tool re-frames it on your device without uploading anything.
How to use crop video
Add your video
Drag in an MP4, MOV, WebM or MKV file, or click to choose one.
Choose a shape
9:16 for Reels, TikTok and Shorts. 1:1 for a feed post. 4:5 for the tallest a feed post is allowed. 16:9 for YouTube and anything on a screen.
Position the frame
Move the crop to keep what matters. Cropping a landscape clip to portrait throws away most of the width, so what you centre on decides the result.
Crop and download
The new file has the shape you chose, with nothing added around the edges.
Frequently asked questions
Which ratio does each platform want?
Instagram Reels, TikTok and YouTube Shorts all use 9:16, full-screen vertical. An Instagram feed post can be 1:1 square or 4:5 portrait, and 4:5 takes up more of the screen so it tends to perform better. YouTube, Vimeo and anything watched on a computer use 16:9. X and Facebook accept all of them and will letterbox whatever does not fit.
What is the difference between cropping and resizing?
Cropping changes the shape by throwing away part of the picture. Resizing changes the number of pixels while keeping the whole picture and its shape. If your problem is grey bars on the sides, you want cropping. If your problem is file size, you want the compressor, which scales the video down without changing the framing.
Will cropping make the file smaller?
Usually, yes — you are keeping fewer pixels, and fewer pixels need fewer bits. A landscape clip cropped to 9:16 loses roughly two thirds of its width. It is not the reliable way to hit a size limit, though; for that, trim the length or use the compressor.
Can I add bars instead of cutting the picture off?
This tool fills the frame rather than padding it, because bars baked into the file are almost never what people want — every platform adds its own if it needs to, and a video with bars already in it can end up with two sets. If you must keep the whole frame, crop to the ratio nearest what you have so as little as possible is lost.
Does cropping rotate a sideways video?
No, those are different problems. A video that plays sideways usually carries rotation information the player is ignoring; converting it to MP4 with the video converter normally settles it. Cropping only changes which part of the frame is kept.
Is my video uploaded anywhere?
No. Cropping runs in your browser on your own device, and nothing is sent to a server at any point.
