About File Size & Bitrate

This tool helps you estimate the size of a digital file. This is useful for video or audio files. You can find the size based on its length (duration) and quality (bitrate). This helps you plan for storage space or data usage.

How to Use It

Enter the **Duration** of the file (e.g., 3 minutes).
Enter the **Bitrate** of the file (e.g., 128 kbit/s).

The estimated file size will be shown automatically.
