Any file type · up to 2 GB
This tool splits a large file into smaller equal parts - useful when you need to transfer a file through a channel with a size limit (like an email attachment cap or a USB drive with limited free space), by breaking it into pieces that can be rejoined later.
Frequently asked questions
Use the File Joiner tool with all the split parts to reconstruct the original file exactly as it was, in the correct order.
Yes - specify your desired part size (like to fit a specific size limit), and the tool divides the file into that many equal-sized pieces.
No - splitting is a purely mechanical division of the file's raw data; nothing about the actual content changes, and rejoining the parts correctly restores the exact original file.
