Video Cropper
VideoCrop and trim video frames locally in your browser.
Video Cropper cuts a video down to the region and the moment you actually need. Drag the crop rectangle over the frame, trim the start and end, optionally drop the audio, and export — useful for cropping a phone recording to remove the room, or lifting one section out of a screen capture. The re-encode runs locally in your browser, so nothing is uploaded and there's no watermark.

Frequently asked questions
Can I crop a video online without a watermark?
Yes — nothing Alvseike exports carries a watermark, on any plan, including the free one. Most free online croppers stamp their logo on the result or hold the clean version behind a subscription; here the file you download is the file you made.
How do I crop an MP4 to a square or 9:16?
Lock the crop box to 1:1 for a square or 9:16 for Shorts, Reels and TikTok, then drag it over the part of the frame you want to keep. The box holds the shape while you move it, so you can't nudge it out of ratio by accident.
Does cropping reduce the video quality?
The kept area is re-encoded, so there's some generation loss as with any re-render — but you choose the output settings, and cropping usually makes the file smaller because there are fewer pixels to store. Crop from the original rather than an already-compressed copy for the best result.
Is there a file-size limit?
No, because nothing is uploaded. The video is read straight from your disk and processed by your own machine, so the limit is your device's memory rather than someone's upload cap — and a private or unreleased clip never leaves your computer.
