Tired of "File Too Large" Errors?

We built ITKB Video Compressor to solve the most common video sharing frustrations:

❌ Social Media Limits Apps like LINE, Discord, or Email have strict size limits (25MB-100MB) that prevent sending high-res clips.
❌ Slow Data Uploads Waiting for hours to upload a heavy video just to share a simple moment is a waste of time and data.
❌ Privacy Concerns Online compressors usually upload your files to their servers, posing a risk to your personal data.

✨ ITKB lets you shrink videos locally. High quality, zero uploads, 100% private.
