Break a large PDF into parts that each stay under the size you need - for email attachments or upload portals. Every part is built and measured, so none goes over the limit.
Choose the limit and every part stays under it.
That page can be compressed on its own; anything still too big is clearly marked.
This tool cuts by size, not by page number.
Split by pages insteadCompress the PDF to a target size instead of splitting it.
Compress PDF to a sizePresets for Gmail (25MB), Outlook (20MB) and common portal limits
Custom limit in KB or MB
Each part is measured, not estimated, so it really fits
Pages are copied as-is - no loss of quality
Optionally compresses a page that is too big on its own
Numbered parts (file-part-01.pdf...) and a single ZIP download
Send a scanned document that is too big for one email as several attachments.
Fit documents into portals that cap each file at 1MB, 2MB or 5MB.
Share a large report in parts that open quickly on a phone.
Email attachments are encoded as text when sent, which makes them about a third larger. A 25MB limit therefore fits roughly 18MB of PDF. The Gmail and Outlook presets already allow for this, so the parts send without bouncing.
The tool fits as many pages as possible into each part, in order, then starts the next one. You choose the size, not the page numbers. To split at specific pages or every few pages, use Split PDF instead.
