This file splitter runs entirely in your browser using JavaScript. When you split files, the processing happens completely on your device. We never upload your files to any server, which means your videos, documents, databases, and sensitive data remain completely private and secure.
Unlike online services that require file uploads, our client-side approach ensures zero data collection, zero server processing, and zero privacy concerns. Your files never leave your computer.
The maximum file size is limited only by your browser's available memory. Modern browsers can typically handle files up to several gigabytes, though very large files may take longer to process.
Yes! You can rejoin split files using file joining tools or command line utilities. On Windows, use "copy /b part1+part2+part3 output.ext". On Mac/Linux, use "cat part1 part2 part3 > output.ext".
It depends on your target use case. For email attachments, use 25MB or less. For cloud storage, 100-500MB chunks work well. For USB drives or physical media, larger chunks (1GB+) are fine.
Yes! This tool is completely free with no hidden costs or subscriptions. We believe privacy-first tools should be accessible to everyone.
We use Google Analytics to track page views for website improvement, but we never see, store, or collect your files. All processing happens locally in your browser.
