Tired of Complicated Video Tools?

We built ITKB Video Speed because we were frustrated with the current options online:

❌ Hidden Watermarks Most "free" tools ruin your content with huge watermarks unless you pay.
❌ Privacy Concerns Uploading personal videos to unknown servers is risky. Your data should stay with you.
❌ Heavy Software Why install 500MB editing software just to speed up a 10-second clip?
❌ Slow Uploads Waiting for cloud processing wastes time, especially with large HD files.

🚀 Our Solution: Browser-based processing. Fast, Private, and No Strings Attached.

Frequently Asked Questions (FAQ)

Q: Where is my video file uploaded?

A: **Nowhere.** Your files are never sent to any server. ITKB uses FFmpeg.wasm technology to process everything locally within your browser. This ensures 100% privacy and security for your data.

Q: Why does the processing sometimes freeze or stop?

A: This is usually due to insufficient RAM or CPU usage. Since the video is processed on your device, high-resolution or long videos require significant memory (1GB+). We recommend closing other browser tabs for a smoother experience.

Q: Which video formats are supported?

A: Currently, we primarily support MP4, MOV, and WebM. For the best results and compatibility across all devices, we recommend using MP4 files.
