    Questions

    How does the other person join the parts?

    With this page’s “Join parts”, or 7-Zip (open the .001 file), or on the command line: copy /b file.zip.001+file.zip.002 file.zip on Windows, cat file.zip.* > file.zip on macOS and Linux. Parts must be joined in order and all of them must be there.

    Can I open a single part?

    No: each part is a raw slice of the file, not a file of its own. Only the joined file opens. To send pieces people can open separately, split the content itself instead (for PDFs, Split PDF).

    What size should the parts be?

    Just under the limit you are working around: 20 MB for most email attachments (Gmail allows 25 MB, Outlook 20 MB), 2 GB or 4 GB for older USB drives formatted as FAT32.

    Are my files uploaded anywhere?

    No. Your files are opened and processed on your device, and the results are saved straight back to it. Nothing is uploaded. How to check.

    Is it free? Do I need an account?

    It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
