A horizontal clip will not fit a vertical feed, a stray coffee cup sits in the corner of the frame, and the speaker is off to one side because the camera was pointing somewhere else. Cropping trims the picture itself — you choose which rectangle of the frame survives, everything outside it is cut away. Drag the frame above, snap to a preset ratio like 16:9, 9:16 or 1:1, and export a clean MP4 with the new framing and no watermark.
Every destination has a shape. Choose the preset that matches where the video is going, then drag the frame to position it.
| Destination shape | What it is for | Preset to pick |
|---|---|---|
| 16:9 — YouTube, slideshows, widescreen | The default landscape shape most players expect | 16:9 — often a no-op on camera footage, a cleanup on mixed sources |
| 9:16 — TikTok, Reels, Shorts, Status | Full-screen vertical where a landscape clip shows letterboxed or tiny | 9:16 — crop the horizontal source down to the tall center strip |
| 1:1 — square feeds and thumbnails | A square tile that reads at every size in a grid | 1:1 — equal sides, no wasted background |
| 4:3 — presentations, classic video | Slightly taller than widescreen for slides and older players | 4:3 — a soft crop from 16:9 sources |
| Custom — ads, banners, embedded players | The publisher specified exact pixel dimensions | Free mode — drag the corners to any size and position |
Output dimensions are shown live above the export button, and every value is rounded to even pixels on export — video encoders require even width and height, so odd numbers are aligned automatically instead of failing the job. Limits checked October 2026.
Three steps in the browser — no editing suite to install, no watermark on the result.
Drop in an MP4, MOV, WebM, MKV, AVI or any other common format. The preview loads in the page so you can see exactly what you are framing.
Move the crop rectangle with a pointer or a finger; pull a corner to resize. Snap to 16:9, 9:16, 1:1 or 4:3 to lock the shape, or stay in Free mode for exact custom dimensions.
Press Crop video and the new framing is rendered in the cloud. Download an MP4 at the output size shown above — same length, same quality, new frame.
The crop keeps the pixel count inside the rectangle you drew. This table shows the usual outcomes before you export.
| Source frame | Crop preset | Output resolution |
|---|---|---|
| 1920 × 1080 | 1:1 | 1080 × 1080 |
| 1920 × 1080 | 9:16 | 608 × 1080 (tall center strip) |
| 1920 × 1080 | 4:3 | 1440 × 1080 |
| 3840 × 2160 (4K) | 9:16 | 1216 × 2160 |
| 1080 × 1920 (vertical source) | 16:9 | 1080 × 608 |
| 3840 × 2160 (4K) | 16:9 | 3840 × 2160 — already that shape |
Cropping does not shorten the video or lower its quality — the kept rectangle keeps its original pixels. File size stays roughly the same because the duration and bitrate are unchanged. If the file also needs to be smaller, run the compressor on the cropped result.
Cropping selects a region of the existing frame; resizing would rescale the whole picture. This tool only does the first, so the surviving pixels are the originals, untouched.
Choosing 9:16 or 1:1 constrains every resize to that ratio — pull a corner and the other dimension follows, so the output never drifts into a weird shape by accident.
H.264 encoders reject odd widths and heights. The rectangle you see is rounded to even values on export, which is why the output dimensions occasionally differ by one pixel from the live preview.
Drag the frame and the corner handles with a finger on a phone or tablet — the layout is built for both, no separate mobile mode.
Guests can crop one video per day up to 250 MB. Signing in brings monthly credits for more files and larger sizes with the same flow.
