Crop Video Online in detail

The crop box sits directly over the video preview once your file loads. Drag the handles to cover exactly the region you want to keep, and the selection maps onto the same WebCodecs and FFmpeg WebAssembly pipeline the rest of the editor uses, so cropping a full-length clip runs in your browser without ever leaving your device.

One limitation worth naming upfront: the selection is manual, not an automatic subject tracker. Some cloud tools advertise an auto-crop that follows a face or a moving subject around the frame. This tool does not attempt that. What it does instead is a precise, one-time crop you control directly, with nothing uploaded to make that guess for you.

When to use this preset

Removing black bars

Screen recordings and old standard-definition footage often carry letterbox bars baked into the frame. Cropping them out leaves a clean, full-bleed picture.

Cutting an unwanted edge

A boom mic dipping into frame, a timestamp overlay, or a sliver of someone else's app window along one side. A crop removes the edge without touching the rest of the shot.

Reframing a wide shot

A landscape recording with too much empty space around the subject. Crop in on the part of the frame that actually matters before publishing.

Fixing a slightly misframed phone recording

Handheld footage rarely lines up perfectly. Crop to the well-composed region instead of reshooting.

Preparing footage before a platform resize

Crop out anything unwanted first, then run the result through the resize tool to hit an exact TikTok, Reels, or YouTube frame.

Frequently asked questions

What does cropping do that resizing does not?

Cropping removes pixels from the edges of the frame and keeps everything inside your selection at its original quality. Resizing scales the entire frame up or down instead, which can stretch or letterbox the picture depending on the target aspect ratio.

How do I select the area to crop?

Once your video loads, a crop box appears over the preview. Drag its corner and edge handles to cover exactly the region you want to keep, then export.

Will cropping lower my video's resolution?

Cropping trims the frame to a smaller pixel area, so the exported file will have lower resolution than the source unless you resize it back up afterward. For most edge-trimming and black-bar removal, the resulting resolution is still plenty sharp.

Is there a watermark on the free export?

No. Exports are free and watermark-free, with no trial period and no account required.

Does this work on vertical or square videos too?

Yes. The crop box works on any source orientation and any aspect ratio, it is not limited to landscape footage.

Can I crop and resize in the same pass?

This tool focuses on cropping. For a specific target size afterward, take the cropped export and run it through the resize tool at /resize, or start there directly and use its own crop fit mode if you already know the exact platform dimensions you need.
