Bitrate Calculator — Convert between video bitrate, duration, and resulting file size. Enter Bitrate, Duration, Target File Size (leave blank to compute) to get an instant, accurate result.

נוסחה

File size (MB) = bitrate (kbps) × duration (seconds) / 8 / 1000 — converting bits to bytes (÷8) and kilobits to the file-size unit (÷1000). Given any two of bitrate, duration, or file size, the third is solved from this relationship.

Enter the Bitrate.
Enter the Duration.
Enter the Target File Size (leave blank to compute).
Click Calculate to see your result instantly.

דוגמה מהעולם האמיתי

Example: With Bitrate = 8000 kbps, Duration = 60 s, the Bitrate Calculator gives Bitrate Kbps: 8000, Duration Seconds: 60, File Size Mb: 60.

שאלות נפוצות

Why divide by 8 in the formula?

Bitrate is measured in bits per second, while file size is measured in bytes, and there are 8 bits in a byte.

Does this account for audio bitrate too?

Enter your video's total bitrate (video + audio combined) for an accurate file-size estimate, since both contribute to the final file size.

What inputs does the Bitrate Calculator need?

You'll need to provide: Bitrate, Duration, Target File Size (leave blank to compute). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Bitrate Calculator?

The Bitrate Calculator applies the formula exactly as calculated — File size (MB) = bitrate (kbps) × duration (seconds) / 8 / 1000 — converting bits to bytes (÷8) and kilobits to the file-size unit (÷1000). Given any two of bitrate, duration, or file size, the third is solved from this relationship. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Bitrate Calculator free to use?

Yes, the Bitrate Calculator is completely free, requires no signup, and runs instantly in your browser.

אודות מחשבון קצב סיביות (Bitrate)

The Bitrate Calculator uses a real, verifiable formula — File size (MB) = bitrate (kbps) × duration (seconds) / 8 / 1000 — converting bits to bytes (÷8) and kilobits to the file-size unit (÷1000). Given any two of bitrate, duration, or file size, the third is solved from this relationship. — so results are accurate every time, not an approximation.
