File Size Converter
Convert between bytes, KB, MB and GB, binary or decimal.
Upload limits are quoted in megabytes, server logs report bytes, and storage vendors count in decimal units while operating systems count in binary ones. That mismatch is why a 2 GB drive never shows 2 GB. This converter translates a figure between bytes, kilobytes, megabytes, gigabytes and terabytes, and lets you choose whether a kilobyte means 1000 bytes or 1024. Results for every unit are listed at once, so you can see immediately whether a file will clear a 25 MB attachment limit. The maths runs as you type and no data is collected.
How to use the File Size Converter
- Enter a number and pick the unit it is currently in.
- Choose binary (1024) or decimal (1000) units.
- Read the equivalent value in every other unit below.
