How do I fix a sideways phone video without uploading it?

Drop the video, pick 90 degrees right or left until the live preview looks upright, then click Rotate video and download the result. FFmpeg runs inside your browser, so the clip stays on your device.

What is the difference between Instant (lossless) and Re-encode?

Instant only rewrites the rotation flag, so it takes seconds with no quality loss, but needs an MP4 or MOV and some old players ignore it. Re-encode redraws every frame, is slower and costs a little quality.

Why does my rotated video still look sideways in some players?

Some players ignore the rotation flag that Instant sets. Run it again with Re-encode (most compatible), or use Bake in current rotation, which redraws the frames so every player shows them upright.

Can I mirror a selfie video so the text is not backwards?

Yes. Choose Flip H for a horizontal mirror or Flip V for vertical. Flips cannot be stored as a flag, so they are always re-encoded, with a Quality choice of Smaller file, Balanced or High quality.

What format is the output and what happens to the audio?

Re-encoded output is always an MP4 using H.264. Audio is copied unchanged when MP4 can hold it, otherwise converted to AAC at 192 kbps, for example WebM with Opus. Very large files may exceed browser memory.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Are my files uploaded?

No. Your files are opened and processed inside your browser and are not sent to LibraTool. Some tools first download a processing engine or AI model to your browser; that download contains no data of yours.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install. Very large files can be slow or run out of memory on a phone, so use a computer for those.

How It Works

Phones sometimes save video with the wrong orientation, leaving it sideways or upside down. This rotates or flips the actual frames with FFmpeg in your browser.

1
FFmpeg.wasm loads once
The WebAssembly build of FFmpeg (~30 MB) downloads on first use and is cached afterwards.
2
You pick a rotation
90° left/right, 180°, or mirror horizontally/vertically — with a live CSS preview so you can confirm before processing.
3
FFmpeg transposes the frames
The transpose/flip filter re-orients every frame; the audio is copied through untouched.
4
You download the fixed video
The correctly-oriented MP4 is offered for download and previewed in-page.
