Frequently asked questions
Is it safe to crop my videos here?
Yes. This tool runs entirely in your browser using WebAssembly. Your files are never uploaded to any server - all processing happens on your device.
What video formats can I crop?
The tool accepts MP4, MOV, and WebM files. The cropped video is always saved as an MP4, which plays on virtually every device and platform.
Can I crop a video to 9:16 for TikTok, Reels, or Shorts?
Yes. Select the 9:16 aspect ratio preset, position the crop box over the part of the frame you want to keep, and download. The 1:1 preset works the same way for square posts.
Will I lose video quality?
The cropped area is re-encoded with H.264 at a quality setting that balances file size and visual fidelity. For most videos, the quality difference is imperceptible.
Is there a file size limit?
There is no hard limit, but very large files (over 500MB) may be slow or run into browser memory constraints. For large files, consider using a desktop tool like Tight Studio.
Can I also trim or add effects to my video?
This tool only crops the frame. For trimming, zoom effects, captions, and backgrounds, Tight Studio desktop app gives you a full editor built for screen recordings and demos.
