Crop Video — FAQ
Is this video cropper really free?
Yes — crop as many videos as you like, free, with no signup and no watermark. An optional Pro membership (NZ$9/mo) adds batch cropping and saved presets, but the free tool is fully usable on its own.
Is my video uploaded anywhere?
No. Your video is read and re-encoded entirely in your browser using a local video engine. The file never leaves your device — there is no server and nothing is stored online.
How does the crop decide what to keep?
We read your video’s real width and height, then take the largest centred rectangle that fits the aspect ratio you picked. The subject in the middle stays put while the edges are trimmed away.
Which aspect ratios can I crop to?
Square 1:1 for grid posts, Portrait 4:5 for the feed, Story 9:16 for Reels, TikTok and Stories, Landscape 16:9 for YouTube — or type a custom ratio for anything else.
Can I turn a landscape listing video into a vertical reel?
Absolutely — crop a wide Auckland walkthrough to 9:16 and it’s ready for Reels, TikTok or Stories. Centre your subject in frame before you film for the cleanest crop.
Does it work on my phone, and why is a big video slow?
It runs in any modern mobile or desktop browser. Because everything happens on your device with a single-thread engine, large or long videos can take a while — especially on a phone. For the quickest result, crop a shorter clip.
