Is Rotate & flip video free? Is there a watermark?

Yes — Rotate & flip video is free to use with no sign-up or watermark. Very large files can still be limited by your browser's available memory and processing resources.

Do my files get uploaded to a server?

No. Rotate & flip video runs entirely in your browser with WebAssembly, so your MP4, MOV, WebM, MKV file never leaves your device and nothing is stored or seen by us.

What can I put in, and what do I get out?

Rotate & flip video accepts MP4, MOV, WebM, MKV and gives you back a MP4 file. You can also set transform before you run it. Actual codec support depends on what the bundled engine or browser decoder can read.

Does Rotate & flip video change my original file?

No. It never touches your original — Rotate & flip video creates a brand-new MP4 file to download and leaves the source on your device untouched.

Best for: Correcting sideways footage, turning a frame 180 degrees, or mirroring an image that was captured in the wrong orientation.
Input → output: The selected transpose or flip filter produces H.264/yuv420p MP4 video with re-encoded AAC audio. Frame dimensions swap for quarter turns.
Quality tip: Confirm whether text and faces are genuinely mirrored before flipping. Check visible pixels so orientation metadata does not cause a double correction.
Know before running: Rotation preserves the full frame but re-encodes picture and sound. It does not crop empty edges, change aspect ratio deliberately, or correct perspective distortion.
Next step: Crop to aspect ratio to compose the corrected orientation for delivery.
