Frustrated with Sideways Videos or Forced Watermarks?

We built the ITKB Video Rotator to solve the most annoying problems you face when trying to simply fix your video's orientation:

❌ Sideways or Upside-Down Recorded a video on your phone, but it plays sideways when transferred to your computer or shared with friends.
❌ Mirrored Text (Selfie Cam) Shot a tutorial or vlog with your front camera, and now all the text on your shirt or signs is backwards.
❌ Privacy Risks Uploading personal or sensitive videos to random cloud servers just to rotate them exposes your data to risks.
❌ Forced Watermarks Many "free" tools let you rotate your video, but force a huge, ugly logo onto your final clip unless you pay.

✨ ITKB lets you rotate & flip videos locally. 100% Secure, completely free, and absolutely NO watermarks!

Frequently Asked Questions (FAQ)

Q: Can this tool fix backwards text from a selfie camera?

A: **Yes, absolutely!** If your front-facing camera mirrored your video and the text is unreadable, simply use the "Horizontal Flip (Mirror)" option to reflect it back to normal.

Q: Will my personal videos be uploaded to your server?

A: **No uploads whatsoever.** We utilize local client-side processing. The entire rotation process happens inside your computer's browser, meaning your private videos are 100% safe.

Q: Will I lose audio or video quality when rotating?

A: Our tool is designed to **copy your original audio track** seamlessly while re-encoding the video frames at a balanced bitrate. This ensures your final clip retains excellent visual quality without losing any sound.

Q: Why did my browser crash when rotating a large file?

A: Since the tool uses your device's RAM to process the video, files larger than 250MB might exceed your browser's memory limit (Out of Memory error). **Quick Fix:** We recommend using our Video Compressor tool to reduce the file size before rotating.
