Important
Check the result before relying on it
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.
Practical details
What this Lucaden tool does
FFmpeg applies a transpose or flip filter to the decoded frames and re-encodes H.264 video with AAC audio. This changes the actual frame orientation rather than relying on metadata alone.
Lucaden writes the source into FFmpeg's temporary in-browser file system, creates the output, then removes both temporary files. The source media is not uploaded to Lucaden.

Questions
About this tool
Does rotating crop the video?
No. Ninety-degree rotations swap width and height; the complete frame is retained.
Will quality change?
Re-encoding can introduce a small change, so keep the source until you have checked the result.
