How it works
A frame from your video renders as a live preview: drag the box to move it, pull the corners to resize, or snap it to 9:16, 1:1, 16:9, or 4:3 with one tap. The crop then re-encodes every frame on your device — hardware-accelerated where your browser supports it — and hands back a standard MP4 with the audio intact. Formats your browser can't display (AVI, WMV and friends) are better converted to MP4 first so you can see what you're cropping.
Next step
A vertical crop is usually headed for a phone screen — fit it under the platform cap next with Instagram, TikTok or WhatsApp presets, or pick any exact size in the video compressor. For a short cropped loop, MOV to GIF and MP4 to GIF run on your device too.
FAQ
How do I crop a video to 9:16 for TikTok or Reels?
Drop the video, tap the 9:16 chip, and drag the box over the part of the frame you want to keep. The crop re-encodes on your own device using its video hardware, so even long clips finish fast.
Does cropping reduce the video quality?
The video is re-encoded — that is what cropping a video means everywhere — but at near-source quality settings, and only the pixels you keep spend bitrate. The result plays everywhere as a standard MP4.
Is the audio kept?
Yes — the audio track is carried into the cropped MP4. Cropping changes only the picture area.
Why can’t I see a preview of my AVI/WMV file?
Browsers can’t display some older formats, and cropping blind would be guesswork. Convert the file to MP4 first — one click on this site — then crop with the full preview. The crop engine itself handles those formats via its fallback.
Is my video uploaded anywhere?
No. The whole crop runs in your browser on your own device — no upload, no server, no queue.
