Data Converter. vs File Size Converter

The most complete data unit converter. Supports bits, bytes, base 10 and 1024. Automatic history, instant copy and 28 languages. Fast, accurate and free!

Convert any file size and finally know what the number means. Type a value in bytes, KB, MB, GB, TB or PB and get the exact answer both ways — live, as you type. Most converters give you a rough number and stop there. File Size Converter shows the exact byte count, switches between decimal (KB, 1000) and binary (KiB, 1024) in one tap, and explains why a "1 TB" drive shows less space once your computer counts it. No rounding surprises, no guessing. WHAT YOU GET - Instant two-way conversion across bit, byte, KB, MB, GB, TB and PB - A one-tap switch between decimal (1000) and binary (1024) so you always use the right unit - An all-units breakdown that shows the same size in every unit at once - Transfer-time estimates for any file over 4G, 5G, Wi-Fi or fiber - A storage planner that shows how many photos, songs and hours of video fit in a drive - A plain-English reference that clears up bits vs bytes, Mbps vs MB/s, and the missing-space mystery PERFECT FOR - Anyone comparing drive or phone storage before they buy - People downloading or uploading big files who want a real ETA - Developers and IT folks who need exact byte math - Students learning how data units actually work WHY NOT JUST SEARCH IT ONLINE A quick web search rounds the answer and ignores the binary-vs-decimal gap that makes your storage look smaller than the box promised.
