I post across TikTok and ins about 10k followers total so I'm constantly resizing the same video for different platforms.
Every "free" tool I tried pulled the same moves: Sign up before you can even test it Watermark slapped on your export The one feature you actually need is behind a paywall Or it just crops badly and cuts off people's faces
Converting 16:9 to 9:16 shouldn't be this annoying.
So I built Freecropper. Took a week and about $200.
Freecropper is a free online video cropper that runs entirely in your browser. Subject detection, no signup, and no watermark.
Upload once and export to multiple aspect ratios (9:16, 16:9, 4:5, 1:1) optimized for TikTok, Instagram, YouTube, Facebook, LinkedIn, Twitter (X), and Reddit.
