Smart Split PDF
Split a stacked batch of invoices or statements into separate named documents.
About Smart Split PDF
How Automatic Splitting Works
A month of invoices arrives as one file. Somewhere inside, page 1 repeats: a new invoice number, a page counter back at 1, a masthead you have seen before. The tool reads the text layer of every page, scores those signals, and proposes where each document begins. You review the groups before anything is written.
OxygenPDF runs the whole pass in your browser. Pick the batch, look over the proposed groups with their page ranges and filenames, merge or rename where needed, then download one ZIP. No account, nothing uploaded.
When the Stack Splits Itself
Nobody opens a 60-page PDF hoping to cut it by hand. These are the batches people actually drag in.
Invoice Batches
Vendors pack a month of invoices into one file. Each one starts with its own number, which becomes its filename.
Bank Statements
Twelve statements, one download. The masthead and the account line mark each boundary, so filing takes seconds.
Scanned Mail Piles
Letters scanned in one sitting land as a single document. Date lines and letterheads tell them apart.
Mixed Exports
Accounting exports glue unrelated documents together. Page-counter resets catch the seams a human would miss.
Review Before Anything Is Written
The review step is the whole point. Every proposed group shows its page range, its derived filename, and the evidence that produced the split, like a page counter resetting to 1 or a fresh invoice number. Read the evidence, not just the filenames.
Merging is the primary action, because the measured failure mode is over-splitting: a mid-document page that looks like a fresh start. Merge two groups back together in one click, or split a group that swallowed two documents. Nothing is written until you approve.
How It Compares
Splitting by hand works on any file. The question is how the boundaries are found, and where your documents go in the meantime.

What It Refuses, and Why
Scanned stacks are refused with a route out, not a silent bad result. With no text layer there is nothing to score, so the tool points at OCR first and waits. Past 300 pages it declines rather than risking the tab, since writing hundreds of output PDFs is the memory cost. And a file that looks like one document says so, offering manual splitting instead of inventing boundaries.
Your batch stays on your device through all of it. Invoices carry names, amounts, account numbers. The detection pass reads that text in your browser and never sends it anywhere. Close the tab and the data is gone.
