Bigger files take longer — your CPU does the work, privately.
Crop to the aspect ratio you need
Pick a target shape above and the cropper center-crops your video to it: 9:16 for vertical (TikTok, Reels, Stories, Shorts), 1:1 for a square feed post, 4:5 for a tall portrait, or 16:9 for widescreen. It keeps the important center of the frame and trims the edges to fit.
This is a true crop — it changes the frame, not just the size. That’s what you want when a platform expects one shape and your footage is another, or when you need to cut out black bars or unwanted edges.
Crop and compress in one step, privately
Cropping runs in your browser with WebAssembly, so your video never leaves your device — no upload, no account, no watermark. The output is a standard H.264 MP4 at your chosen shape, ready to post.
You can also set a target size or trim the length at the same time, so the cropped clip is ready to share without a second tool. For the sharpest result, keep the resolution and crop from the highest-quality source you have.
Frequently asked questions
How do I crop a video online for free?
Drop your video in, pick a target shape (9:16, 1:1, 4:5 or 16:9) in the crop control, then compress and download. The frame is center-cropped to that ratio in your browser — nothing is uploaded.
Does this actually change the aspect ratio?
Yes — it’s a real crop, not just a resize. The cropper cuts the frame to your chosen shape (e.g. landscape to vertical 9:16), keeping the center and trimming the edges.
Can I crop an MP4 to 9:16 for TikTok or Reels?
Yes. Choose 9:16 and the tool center-crops your clip to vertical, then outputs an MP4 ready for TikTok, Reels, Stories or Shorts.
Is my video uploaded to crop it?
No. Cropping runs entirely in your browser on your own device — your video is never uploaded, and you can go offline once the page has loaded.
