Video cropper that runs onyour own machine
Crop to an exact rectangle, or reframe a whole video to vertical with face tracking. Either way the file never leaves your PC — no upload queue, no size cap, no watermark on the way out.
How to use the video cropper in three steps
Online croppers make you upload a gigabyte of footage to somebody's server, wait in a queue, and accept a watermark for the trouble. Shorz is a desktop app: the crop happens on your own disk, at your own speed, on files of any size. And when what you really need is landscape-to-vertical, face tracking does it properly instead of chopping out the middle.
Say what to crop
Give the width, height and centre point for an exact rectangle — or just describe it to the AI assistant you've connected to Shorz and let it work the numbers out.
Pixels, or plain language
Or reframe the whole project
Switch the project to 9:16, 1:1 or 16:9 and let face tracking follow the speaker through the crop, so nobody ends up half out of frame when they lean forward.
Face-tracked reframing
Get a new file back
Shorz writes a new video and leaves the original untouched, so you can re-crop with different numbers as many times as you like. No watermark, ever.
Original never modified
Find it in the app under MCP single-file tool · in-project: aspect ratio + face tracking.
Why Video Cropper in Shorz
Talk to it instead of clicking
Shorz speaks MCP, so Claude, Cursor, Codex or Gemini can crop a file — or a folder of them — from one instruction. "Crop all of these to square, centred on the speaker" is a sentence, not an afternoon.
Batch it with an agent
Cropping that keeps the subject
A centre crop is fine for a locked-off shot and terrible for anyone who moves. Face tracking recalculates the crop frame by frame, which is what makes a repurposed vertical clip look like it was shot vertical.

Who uses it, and for what
Landscape → vertical

Square for feeds

Shorz speaks MCP
Shorz isn't a locked web app. Connect it to Claude, Cursor, Codex or Gemini and your assistant can drive it directly — one message instead of a panel full of clicks. You review before anything is published.

Video Cropper questions
No. Shorz is a desktop app — cropping happens on your own machine, so there's no upload, no queue and no file-size limit.
No. Shorz never watermarks output, at any tier.
The exact-rectangle crop is one of Shorz's single-file tools, driven over MCP — you ask the AI assistant you've connected (Claude, Cursor, Codex or Gemini) and it runs it. Inside a project, cropping is handled by switching the aspect ratio with face tracking on.
Cropping writes a new file and leaves the original untouched, so you can re-run it with different values without degrading your source.
Yes — the same tool crops local images as well as video.
