File Splitter

Split a big file into equal parts for email or upload limits.

How to use

  1. Drop in the large file.
  2. Choose a part size (e.g. 10 MB for email limits).
  3. Download the numbered parts one by one.

Frequently asked questions

How do I put the parts back together?

Use our File Joiner - or on macOS/Linux run cat file.part* > file. Parts must all be present and in order.

Are the parts usable on their own?

No - each part is a raw slice of the original bytes, only meaningful once rejoined.
