Common questions
Frequently Asked Questions
What size limits can I set?
Set any maximum file size from 1 MB to 100 MB per part. Common choices: 10 MB for email, 25 MB for Gmail.
How are pages divided?
Pages are grouped sequentially until the size limit is reached, then a new file begins. No page is split mid-content.
Can I split for email attachment limits?
Yes. Set the limit to your email provider's attachment size (e.g., 25 MB for Gmail, 10 MB for Outlook) and each part will fit.
How many parts will my PDF be split into?
It depends on the original file size and your chosen limit. The tool shows the number of parts before you confirm.
