PDFSplitter Pro turns the tedious task of breaking up large PDF documents into a fully automated workflow. Its signature Watch Folder feature monitors a designated folder and automatically splits any incoming PDF in the background — set it once and run in automation mode indefinitely. Built natively for macOS and Windows, it handles hundreds of files in batch at lightning speed, entirely offline, with bookmarks preserved in every output file.

Key Features

Watch Folder Automation

Set a folder to monitor and PDFSplitter Pro automatically splits any incoming PDF into smaller files in the background — configure post-processing options for source files after successful splitting, and run in automation mode indefinitely.

Split by Page Count

Divide large PDF documents into equal segments by specifying the number of pages per output file — ideal for splitting scanned books, reports, and combined archives into uniform chapters.

Split by File Size

Automatically split PDFs whenever the accumulated content exceeds a specified file size threshold — perfect for creating email-friendly document segments under attachment size limits.

Split by Bookmark Outline

Automatically segment complex publications, eBooks, or legal bundles based on their internal top-level bookmark outline — with an option to use outline labels as output split filenames.

Split Labeling & File Naming

Customise output split file names by adding a label before or after the original filename with a separator — or automatically use the bookmark outline label as the filename when splitting by outline.

Bookmark Preservation

Split PDFs preserve the original document's bookmarks in each output file — maintaining full navigability across all segments without manual re-entry.

Password-Protected PDF Support

Split password-protected PDF documents by providing the correct password — no need to remove security before processing.

High-Volume Batch Processing

Process entire directories of PDFs simultaneously with recursive subfolder scanning, source folder hierarchy preservation, and per-PDF output folder creation at the destination.

Standalone & Fully Private

No Adobe Acrobat, internet connection, or cloud service required. All splitting runs natively on your Mac or Windows PC — your documents never leave your device.

“OMG! Awesomely sweet”

While preparing assorted exhibits for upload to the Court, I belatedly realized that several of the planned exhibits were too porky to meet the Court’s 3mb upload limit per file. This was the first time after my Mac conversion that I confronted this particular dilemma. Long story short, I worked my way through a mess of apps before finally finding this goodie. I simply entered the file size limit, tapped a button, and it was done. When I thi…

“Great time saving application!!!”

While most PDF application can split documents, it is difficult to find one that does that according to file size. My task was to split a 50+MB PDF into parts of max.5MB in order to go through to someones email inbox. Super PDF splitter did that with a few clicks, working in the background. Really useful app, saved me about an hour of dumb work. Thank you!

“I spent years trying to find this app”

Big and many thank you's to the Superapps team. Myself and 100s of other people on forums around the world have needed an app like this for ages. I use it in conjuction with Indesign to create single PDFs with individual names. In my case, I have to produce 100s of certificates from training we provide. Each certificate is emailed individually as a PDF and needs the training participants' name as the file name. This involved alot of manual s…

“Awesome! Saved my bacon!”

I’m a pretty savvy end-user who, due to my profession, must send moderate to large sized documents fairly frequently by email.

“Works Perfectly”

I just used this program to split an 11,000 page PDF file with 200+ bookmarks into 200+ files, each given the name of the corresponding bookmark. It did the job perfectly.
