How Big Is This File?
See the exact size of any file in bytes, KB and MB, and check whether it fits an upload limit.
Why sizes look different
Some apps count 1 KB as 1,000 bytes and others as 1,024. Fylix shows both so you can match whichever a website uses.
Too big?
If a file is over the limit, use one of the compress tools to make it smaller.
Frequently Asked Questions
No. The size is read by your browser; the file never leaves your device.
