About Data Size Converter
Convert between bytes, KB, MB, GB, TB, and PB instantly with real-world comparisons and storage visualizations.
The Data Size Converter transforms digital storage values between all common units - from Bytes to Petabytes. It includes real-world comparisons (like 'equivalent to X photos' or 'X hours of HD video') and a visual storage capacity bar to help you understand data sizes in practical terms.
How to use Data Size Converter
Enter a value and select the unit (Bytes, KB, MB, GB, TB, PB). The converter instantly shows equivalent values in all other units, with real-world comparisons and a visual storage indicator. Use the slider for dynamic size adjustment.

Helpful questions
What's the difference between MB and MiB?
MB (Megabyte) uses decimal (1,000,000 bytes) while MiB (Mebibyte) uses binary (1,048,576 bytes). Storage manufacturers use MB (decimal), while operating systems often use MiB (binary), which is why a '500 GB' drive shows as ~465 GiB.
How many photos can 1 GB hold?
Approximately 250-500 photos depending on resolution and format. A typical smartphone photo (12MP JPEG) is about 3-5 MB, so 1 GB holds roughly 200-333 photos.
How much storage do I need?
It depends on usage. Casual users need 128-256 GB. Photographers/videographers need 1-4 TB. Businesses vary widely. Consider future growth when choosing storage capacity.
Why is my hard drive smaller than advertised?
Manufacturers use decimal units (1 GB = 1,000,000,000 bytes), but operating systems use binary units (1 GiB = 1,073,741,824 bytes). A '1 TB' drive shows as ~931 GiB in your OS.
