Croppy Croppy

Crop video for social without cutting the subject out of shot.

Everything is shot wide and posted tall. Squeezing 16:9 footage into 9:16 throws away two thirds of the picture, and whatever you were actually filming is usually somewhere in the part you just cut off. Croppy does the tedious part: keeping the subject in shot while the crop moves with them.

Every shape you have to post in

One clip, filmed once, usually has to go out in three different shapes. Croppy reframes it for each without re-shooting and without letterboxing.

9:16
Tall video: Reels, Shorts, TikTok, Stories.
4:5
The tallest a feed post is allowed to be.
1:1
Square, for feeds and previews that crop to it.
Anything
16:9, 21:9, or a ratio you add yourself.

Mark the subject. Croppy follows it.

Draw a box round the person and press Generate. Croppy tracks them through the clip and turns their path into ordinary keyframes — so anything it gets wrong, you fix by dragging, not by starting again.

Mark it more than once, from different angles, and the tracker has something to fall back on when the subject turns away or passes behind something.

The result is keyframes on an ordinary timeline, with the path drawn over the frame. Nothing is locked away in a tracking mode.

Or do it by hand.

Place a keyframe, scrub, move the crop, place another. Croppy pans between them, arriving exactly on each one. Set how long each move takes, or hold position and cut.

Playback walks the crop along the timeline as it plays, so a pan is visible in place — you never render something just to find out whether it works.

Everything else

Any ratio
Presets for 1:1, 9:16, 4:5 and 16:9, your own added in Settings, or drag any rectangle you like.
Placed exactly
Six alignment buttons for the edges and centres that dragging can get near but never land on.
Trim and scale
Cut the ends off before exporting, and scale the output anywhere from 2160p down to 360p.
Hardware encoding
Croppy finds the encoder your machine can actually run — NVIDIA, AMD or Media Foundation — by trying them.
Proper transport
Frame-by-frame stepping, playback from 0.25× to 4×, and a filmstrip you can scrub.
Your source is safe
The original file is never modified. Every export writes a new file you choose.

What it doesn't do

No account. No subscription. No watermark. No upload — your video never leaves the machine, and there is no code in Croppy that could send it anywhere: the ffmpeg it ships with is built with networking compiled out, so the installed application has nothing in it that can open a socket.

And it stays out of the way

Croppy follows your Windows light or dark theme and your accent colour. If you would rather it used an ffmpeg you installed yourself, point Settings at it and that one wins.

Post it tall. Keep what you filmed.

Privacy

Croppy collects nothing, sends nothing, and contains no code that could. There is no telemetry, no analytics, no crash reporting, no account and no sign-in. Your video files are read from and written to the locations you choose, and are never copied anywhere else.

The only thing kept between sessions is a settings file in Croppy's own application data folder: the folders you last used, your chosen ratio, output height, theme and volume, and which video encoder your hardware was found to support. Deleting it resets Croppy to its defaults and loses nothing else.

The purchase itself is handled entirely by Microsoft, under the Microsoft Privacy Statement. Writing to support means your message and address reach a mailbox, which is the only way anyone can reply to you; it is used for nothing else.
