What the crop does

The crop cuts your video down to a new shape and keeps the middle of the picture.

  • The crop window sits in the middle of the frame, so the same amount comes off both edges.
  • The part you keep keeps its own pixels, so nothing is stretched or blown up.
  • The picture is written again once at a high quality setting, so the loss is hard to see.
  • If nothing may be cut, switch to Pad and keep the whole picture with bars around it.

How much each shape keeps

The further the new shape is from the old one, the more is cut.

What a crop keeps

Crop sizes from a 1080p clip. The crop is taken from the centre and never blown up.

Limits of a browser tool

Everything runs on your own device, so your device sets the limits.

  • File size: up to 500 MB runs comfortably. Bigger files may run out of memory.
  • Speed: the engine uses one processor core, so a long re-encode takes minutes.
  • First run: the engine downloads once, about 32 MB. After that it starts fast.
  • Phones: it works, but a laptop is faster and has more memory.
  • The crop is always centred, so it cannot follow a person or a product that moves around the frame.

Questions people ask

Can I choose which part of the video to keep?
No, the crop is always taken from the centre. Film with the subject in the middle, or use Pad to keep the whole picture.
How do I crop a video to a square?
Keep 1:1, which is set for you, and press Resize. From a 1080p landscape clip you get 1080 × 1080.
Does cropping lower the quality?
It keeps fewer pixels but does not blur them. The picture is written again once at a high quality setting (CRF 21), so the loss is hard to see.
Can I crop out a border or a logo in a corner?
Not precisely. The crop picks a shape from the centre, so it only removes edges evenly on two sides.
Is my video uploaded anywhere?
No. The tool runs inside this browser tab, so your video never leaves your device. Only the engine itself is downloaded, about 32 MB, once per visit.
