Frequently Asked Questions
Why should I split files?
Email services limit attachments (usually 25MB). Cloud storage has upload limits. Splitting lets you send/store large files in manageable chunks.
Are my files sent to a server?
No. All splitting happens entirely in your browser using JavaScript. Your files never leave your device — verify in DevTools Network tab.
What file types can I split?
Any file type: videos, archives, documents, images, executables, PDFs — anything you need to divide.
Can I rejoin the split files?
Yes. Use the File Merger tool here, or command line (cat parts.001 parts.002 > original). Parts are numbered sequentially.
Will splitting damage my file?
No, splitting is 100% safe. It's a basic binary operation. Rejoin the parts in order to restore the original file perfectly.
