Frequently asked questions

Is splitting a PDF by size free?

Yes, free and private. There is no account and no limit on how many documents you split.

Is my heavy PDF uploaded to be split?

No. The file is divided locally in your browser, so even a very large PDF never leaves your computer.

Do I need an account for this?

No account or registration is required. Load the PDF, pick a maximum size and download the parts.

How does the size-based splitting work?

You choose the maximum size per part and the PDF is cut into consecutive chunks under that limit, which is handy for services with attachment size caps.

How do I receive the parts?

As a single ZIP containing one PDF per part, in order, so you can attach or share each piece separately.
