Frequently asked questions

What is the right size for TikTok and Reels?

TikTok, Instagram Reels and YouTube Shorts all use the vertical 9:16 format, ideally 1080 × 1920 pixels. This tool converts any video to exactly 1080 × 1920.

What is the difference between blur fill, crop and fit?

Blur fill keeps your whole video visible and fills the empty sides with a blurred copy of the footage (the most popular look). Center crop zooms in so the video fills the frame — parts of the sides are cut off. Fit with bars shrinks the video to fit and adds black bars top and bottom.

Does my video leave my device?

Never. The video engine (a WebAssembly build of FFmpeg, loaded unmodified from a CDN) runs entirely on your device. Your file is processed locally and is never uploaded to any server.

Is the 9:16 conversion really free and watermark-free?

Yes — 100% free, no signup, and your converted video exports clean with no watermark. There are no limits on how many videos you convert.
