Split any file into equal-size parts in your browser. Parts download as one ZIP, numbered with natural zero padding.
The parts download as one ZIP, zero-padded for correct ordering.
Your file is never sent to a server. It is read and processed by your own browser, and the results are not stored.
Email, chat tools and form limits all bite in the same way: the file is 30 MB and the limit is 25. Splitting into parts you can attach separately is the boring, universal answer, and zero-padded numbering is what keeps the parts in order on the receiving end.
If your receiving system will not rejoin, split the source, reassemble elsewhere, and keep both halves: that is the actual use case for this tool.
A split part is a slice of the original bytes — no recovery metadata, no index, no checksum inside it. Joining is concatenation. That is the same contract as split(1) on Linux, and it is why any tool can rejoin parts from any other tool.
No. File Splitter runs in your browser, and the file is read there rather than sent to a server for processing. Our host still sees ordinary page-request metadata, which is described on the privacy page.
Yes, File Splitter is free, with no paid tier, no account, and no watermark added to your output. The limits are technical rather than commercial: file size, page count and supported formats are listed on this page.
File Splitter supports * files up to 512MB directly in your browser.
Use the File Joiner on this site: it orders parts by name, joins them and reports the exact byte count. The parts are ordinary contiguous chunks.
Browsers block multiple automatic downloads. One ZIP with well-ordered parts is one click, and it preserves the exact naming scheme the joiner expects.
512 MB per source file, and no more than 100 parts. Choose the part size to suit whatever you are splitting the file for.
The last part is smaller when the file does not divide evenly — exactly how split(1) behaves.
