Crop Video
Crop a video for TikTok, Instagram, YouTube, or anywhere else. Use a ready-made aspect ratio or freely reposition and resize the crop box. Private, free, and no watermark.
Crop videos for every platform
Use a 9:16 crop for vertical video, 1:1 for a square social post, 4:5 for the Instagram feed, and 16:9 for YouTube or a product demo. The original video stays on your device while MobileStudio exports a newly cropped MP4.

FAQ
Video cropping questions
Is my video uploaded to a server?
No. The video is cropped and encoded by your browser on your own device. It never leaves your device.
What size should I crop to for Instagram or TikTok?
Use 9:16 for TikTok, Reels, and Stories, 4:5 for the Instagram feed, 1:1 for square posts, and 16:9 for YouTube.
Does cropping lower the quality?
Cropping keeps the original pixels inside the box, so detail stays the same; the frame is just smaller. The video is re-encoded in high quality.
Is the sound kept?
Yes. The original audio is kept in the cropped video.
Is there a watermark?
No watermark and no account.
