Select the video recorded sideways or upside down directly from your local storage drive.
Rotation Axis
Choose the required correction angle: 90° clockwise, 90° counter-clockwise, or a complete 180° flip.
Permanent Export
The WebAssembly script applies the spatial transformation. Download your properly oriented video.
Why modify orientation and rotate your video files?
Video orientation issues are incredibly common when recording on the go using a smartphone. If you start filming in a portrait layout before flipping the device horizontally, your phone's internal gyroscopic sensor can freeze the wrong canvas angle. This results in a frustrating playback experience where your video displays sideways or upside down on computer screens or Smart TVs. Our online utility solves this layout flaw by rendering a permanent structural correction straight into the core video stream matrix.
By embedding a high-performance compiler powered by FFmpeg WebAssembly, the application directly processes native video transformation filters like transpose or flipping mechanisms like vflip,hflip. This transcoding runs inside an ultra-fast rendering pipe (-preset ultrafast) designed to maximize client-side writing speed. Your media assets, professional footage, or family clips never leave your web browser, removing any vulnerability risks related to third-party cloud infrastructure.
Frequently Asked Questions
Is the rotation applied by this tool permanent?
Yes, completely. Unlike desktop media players that only flip the screen viewport temporarily during playback, our script re-encodes the actual geometric metadata and internal structure of the video so it displays facing the right direction on all media players.
Which video containers are supported for re-orientation?
The local engine powered by FFmpeg supports a comprehensive variety of input containers (MP4, MOV, AVI, WebM, MKV) and exports your corrected sequence as a universally compatible, standard MP4 file.
