File Splitter

Welcome to the Free Online File Splitter. Need to email a massive 200MB video but Gmail limits you to 25MB? Trying to upload a giant dataset to a portal with strict file size limits? Our tool solves these problems instantly by slicing your large files into smaller, manageable chunks.

How to split your files

Simply upload your large file and choose your splitting method. You can either specify a Maximum Chunk Size (e.g., exactly 25MB per piece) or define the Number of Parts you want (e.g., split into 4 equal pieces). We will instantly slice the binary data and package all the parts into a convenient ZIP archive for you to download.

100% Secure & Local

Your massive files are never uploaded to our servers. We use advanced HTML5 Blob slicing technology to partition your files directly inside your computer's RAM. This means the process is blazingly fast—limited only by your hard drive speed—and offers absolute, uncompromising data privacy.
