About this tool

IconVault's File Splitter breaks a large file into smaller chunks by count or by size (KB or MB), then merges them back into the original byte-for-byte. Every chunk shows a SHA-256 checksum so you can verify integrity after transfer. It is free and runs fully in your browser.

Splitting is useful for email attachment limits, upload size caps, or moving big files on a USB stick in pieces. Your file is processed locally in memory, so nothing is uploaded and your data never leaves your device.
