About the Crop Video for Reels and Shorts
The Crop Video for Reels and Shorts crops a landscape video to 9:16, 1:1 or 4:5 from the centre, so it fills the frame on Reels, Shorts and TikTok. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Reposting a landscape video as a Reel or Short.
- Making a square version for a feed post.
- Getting one recording onto several platforms.
The first tool you run downloads the 31 MB WebAssembly engine once; after that it starts instantly. Processing speed depends on your own machine — a browser build is several times slower than desktop FFmpeg, so a long 4K file will take a while. The trade is that nothing is uploaded and nothing is queued behind other people.
Frequently asked questions
Which part of the frame is kept?
The centre. Going from 16:9 to 9:16 discards about two-thirds of the width, so anything important has to already be in the middle third — worth knowing before you shoot rather than after. The Aspect Ratio Calculator on this site shows exactly how much each platform costs you.
Is my video uploaded to a server?
No. FFmpeg is compiled to WebAssembly and runs inside this browser tab, on your own processor. You can watch the Network tab while it works — no request carries your file. That is also why there is no queue, no size cap set by us and no watermark.
Why is the first run slow to start?
It downloads the 31 MB engine once. Your browser caches it, so every later run on this site starts immediately. The processing itself is unaffected.
How big a file can I use?
There is no limit we impose — the ceiling is how much memory your browser will hand the tab, typically 2–4 GB on desktop and much less on a phone. If a very large file fails, try trimming it first or use a lower output resolution.
Why is it slower than a desktop program?
WebAssembly runs at roughly half to a third of native speed, and this build is single-threaded because the multi-threaded one needs security headers that would break other parts of the site. For a short clip the difference is seconds; for a feature-length 4K file, use a desktop tool.
Is the Crop Video for Reels and Shorts free, or is there a paid tier?
It is free, with no account, no trial and no daily cap. Every video & audio tool on inputtesthub.com works the same way: open the page and use it.
Can you see what I put into this tool?
No. The Crop Video for Reels and Shorts runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
What problem does the Crop Video for Reels and Shorts solve?
The most common reasons people reach for it: reposting a landscape video as a Reel or Short. Making a square version for a feed post. Getting one recording onto several platforms. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there anything to watch out for?
The first tool you run downloads the 31 MB WebAssembly engine once; after that it starts instantly. Processing speed depends on your own machine — a browser build is several times slower than desktop FFmpeg, so a long 4K file will take a while. The trade is that nothing is uploaded and nothing is queued behind other people.
Will a big file be rejected?
There is no limit set by us, because your file is never uploaded — the only ceiling is the memory your own browser will give the tab. Very large files simply take longer to process, and a phone will give up sooner than a desktop.
