Split a PDF by target file size
Set a maximum megabyte ceiling for each segment. Ensure heavy graphic presentations and scanned portfolios bypass email and portal caps effortlessly.
Set your size limit
Choose from standard presets like 5MB, 10MB, 20MB, or 25MB. Our local sizing calculator scans your document structure and segments the pages into sequential parts, each guaranteed not to breach your chosen threshold.
If your document simply has too many pages and you just want an even cut down the center, you can split into two equal halves with zero configuration.
Why this matters for email attachments
Google Workspace, Gmail, Microsoft Outlook, and corporate Exchange mail servers enforce a strict 20MB to 25MB attachment limit. Attempting to send a 60MB design tender or court appendix triggers immediate bounce-backs.
By slicing your large document into sequential chunks that each remain under 25MB, you can easily distribute Part 1, Part 2, and Part 3 across multiple messages without resorting to unvetted cloud storage file links that might expire or trigger corporate spam firewalls.
