Keep the part
that matters.
Drag a crop box over your video — or pick TikTok, Reels, or Instagram sizes — and export. Locally re-encoded, nothing uploaded, no watermark.
How do I crop a video for free? Load the MP4 or MOV, drag a box over the preview (or press a preset like 9:16 for Shorts/Reels), then press Crop & export. The kept area is re-encoded on your device into a new MP4 — no upload, no watermark.

Drag inside the box to move it; drag outside to draw a new one. 9:16 = TikTok / Reels / Shorts · 4:5 = Instagram feed · 1:1 = square. Rotated phone videos are normalized automatically.
Why crop instead of resize
Turning a landscape clip into a vertical video has two routes: crop (keep a vertical slice, lose the sides) or pad/zoom (keep everything, look worse). Cropping is what editors actually do for Shorts and Reels — the subject fills the frame and nothing looks stretched. This tool does that without an editor: draw the slice, export, upload.
How to get a good crop
- Presets first — 9:16 places the largest vertical crop; drag it over your subject to reframe
- Scrub to check — play through the clip and watch what leaves the frame; if the subject moves, size the crop for their whole path
- Leave headroom — for talking heads, put the eyes on the upper third line (the rule-of-thirds guides are drawn on the box)
- One generation only — export once from the original; avoid re-cropping an already cropped file
Honest limits
The kept area is re-encoded once (H.264 at a bitrate near the source) — this is not a lossless operation like the video trimmer or rotate tool, because the pixels must be re-arranged. Audio passes through at 128 kbps AAC. If your clip is also too big to upload, crop first, then run it through the video compressor — cropping alone often already saves plenty.
How do I crop a video?
Load the MP4 or MOV, drag a box over the preview (or pick a preset like 9:16 for Shorts), then press Crop and export. The tool re-encodes the kept area locally — nothing is uploaded.
Can I crop a video for TikTok, Reels, or Shorts?
Yes — pick the 9:16 preset for vertical video platforms, 4:5 for Instagram feed, 1:1 for square posts, or 16:9 for widescreen. The preset places the largest crop of that shape, and you can drag it to reframe.
Does cropping reduce quality?
The kept pixels are re-encoded once at a bitrate near the original, so there is one generation of encoding — far less loss than resizing or repeated edits. Nothing is upscaled, so there is no softening from stretching.
Does the output still contain the cropped-out area?
No. The exported file contains only the pixels inside your crop — the rest is simply not written. If you are cropping to hide something (a face, a watermark, a background), that area is genuinely gone from the new file.
Which formats are supported?
Input: MP4, MOV, and M4V with H.264 or HEVC video. Output: MP4 (H.264 + AAC). Rotated phone videos are normalized to their display orientation, so the crop you draw is the crop you get.
