Split large files into smaller parts and merge them back. Pure browser-based, no upload needed.
How do I split a large file?
Upload your file, choose to split by size (KB/MB/GB) or by number of parts, then click Split. You can download parts individually or as a ZIP file.
How do I merge split files back together?
Switch to the Merge tab, upload all the part files, optionally upload the manifest file generated during splitting, and click Merge. The original file will be reconstructed.
What is the manifest file?
The manifest file (JSON) is generated when you split a file. It contains the original file name, size, and part order, making it easy to merge files back in the correct order.
Is my file uploaded to a server?
No, all splitting and merging happens locally in your browser. Your files never leave your device, ensuring complete privacy.
