Frequently asked questions

How do I crop video to 9:16?+

Drop the video, set the options, and press Process. The vertical middle slice of the frame is kept — ideal when your subject is centred. Then download the WebM output — entirely in your browser.

Why is the output WebM and not MP4?+

WebM is the only video format browsers can encode natively without shipping a 30 MB ffmpeg download. It plays in every modern browser, WhatsApp, Telegram, YouTube and most editors; convert to MP4 with a desktop tool if a legacy device demands it.

Why does processing take as long as the clip?+

The browser re-records the video in real time as it plays through a canvas — that's what makes a fully private, no-upload tool possible. Trim the range first to process just the part you need.

Is my video uploaded?+

No. Everything happens locally; your footage is never sent to a server.
