FilePresto

Rotate video

Turn a video that was filmed sideways or upside down. Choose the turn and convert as many videos as you like. Everything happens on your own device, using the video engine built into your browser, so your video is never uploaded.

Your files never leave your device

How to use it

  1. Choose which way to turn the video.
  2. Choose your videos, or drag them onto the box.
  3. Download each video, or all of them together as a ZIP file.

How it works

Where possible, the turn is recorded in the file so the video is not encoded again and keeps its full quality; players then show it the right way up. Almost every current player follows this instruction.

What is kept

The main video and its sound are kept. Subtitles and any extra sound tracks, such as a second language, are left out, and the result says when this has happened.

Limits

Videos are converted in the browser's memory, so very large files are refused before anything starts; the page shows the largest size tested on your kind of device. Long videos take a while, and the page must stay open and on screen while it works, particularly on a phone.

The page reads what is inside each file before it starts. Dolby Digital (AC-3) sound, which many camcorders use, is read by FilePresto's own converter, on your device. A few formats cannot be converted yet: WMV videos, and Dolby Digital Plus (E-AC-3) and DTS sound. If a file has sound that cannot be read, the page stops and says so, rather than making a silent video; you can then choose to convert the video without its sound.

Questions

Are my files uploaded?

No. The work happens inside your web browser, on your own device. Before your file is opened, this page locks itself: from then on your browser refuses to let it fetch, upload or send anything at all. You can check: once the page has loaded, switch off your internet connection and it will still work. How the lock works.
