How it works
- Choose your videoOpen an MP4, MOV, WEBM or MKV saved on your device.
- Choose what staysPick 9:16, 1:1, 4:5, 16:9, 4:3 or custom pixels. Choose centre or an available edge position, then check the dimensions.
- Crop and savePress Crop video, preview the result, then download the MP4. Keep your original if you might need the edges later.
Crop landscape video for TikTok, Reels or Shorts
Choose 9:16 for a tall frame. A 1920 × 1080 landscape clip becomes 606 × 1080 here. The tool cuts away the sides instead of enlarging the picture to 1080 × 1920. Dimensions round down to even pixels, so the shape can differ slightly from the ratio you chose.
Keep the centre for a subject in the middle. Choose left or right when the subject stands near an edge. The position stays fixed for the whole clip; it does not follow people as they move.
Square, portrait, wide or custom pixels
Choose 1:1 for a square, 4:5 for a portrait post, 16:9 for a wide picture or 4:3 for a less wide frame. Each shape keeps the largest region that fits inside your source. For a 1920 × 1080 clip, square keeps 1080 × 1080 pixels.
Custom width and height let you keep a smaller region. Enter whole numbers of at least 16 pixels, no larger than the original dimensions. Odd numbers round down. Centre keeps the middle; top or bottom moves the region vertically, and left or right moves it horizontally while centring the other direction. Only positions that can move the crop are offered.
Crop vs resize vs rotate
Cropping removes part of the picture. Resizing changes its pixel dimensions and can keep everything visible with bars. Use resize video when you need an exact output size such as 1080 × 1920, or want the whole shot to stay.
A sideways recording needs a turn before you decide which edges to remove. Use rotate video first. To shorten the running time instead, use trim video.
Quality, sound and practical limits
The retained picture is not enlarged. Saving the cropped MP4 does make the picture again, so this is not a promise of lossless quality. Sound is copied unchanged when it fits the output; otherwise it is converted. Cropping keeps the clip’s running time.
Processing takes place on your device. Long or large videos can take time and need free memory. An estimated result above about 1 GB may be refused. Keep the tab open until the download is ready.
Removing a border or black bars
There is no automatic black-bar detection here. If you know the size of the picture inside the bars, enter that width and height under Custom. Use centre for equal borders, or an edge position for a border on one side. Preview the saved result to check that you kept the content you wanted.
There is no draggable crop box or moving crop path. The same region is kept from start to finish.
What the crop keeps
The dimensions shown above the Crop video button are the dimensions of your result. Output size in bytes depends on the clip.

Questions
How do I crop a video for TikTok or Instagram?
Choose 9:16 for a tall TikTok or Instagram Reel, 1:1 for a square or 4:5 for a portrait post. Pick where the subject stays and check the output dimensions. Cropping cannot keep everything from a wide shot inside a tall frame.
Can I crop video without losing quality?
The kept region uses the original pixels and is never enlarged, but the picture is saved again as an MP4. Some quality can change. Keep the source file if you need an untouched original.
How do I crop a video on iPhone or Windows?
Open this page, choose a video saved on your iPhone or Windows computer, then select the shape and position. Press Crop video and save the MP4 when it is ready. Available memory and browser support can limit large files; try a shorter clip if processing fails.
What is the difference between cropping and resizing video?
Cropping cuts away edges. Resizing makes the picture larger or smaller, or fits it inside a different frame with bars. This crop tool keeps source pixels; the resize video tool lets you choose an exact output size.
Can I crop a video into a square?
Yes. Choose 1:1. A landscape clip loses its left and right edges; a portrait clip loses its top and bottom. Choose an available position to keep the part you need.
Is my video uploaded?
No. It is processed inside this browser tab and saved straight back to your computer.
