Split a PDF by Its Content and Name Each File Automatically by AIMerger

Scanned 40 invoices into one PDF? Split it wherever a page says “Invoice No”, at blank separator sheets, every N pages or by bookmarks — and name every file from text inside it, like INV-1001.pdf or the customer’s name. Check every split and name in a table before you save.

Split & download

One PDF per part in a ZIP, plus a summary CSV.

🔒 Split and named on your device. Nothing is uploaded.

Limits on this device

PDFs up to about 1,500 pages on a computer, less on phones. Text-based rules need selectable text; scanned pages can be read with English OCR first (a few seconds per page). Names keep letters from any language; characters that aren’t allowed in file names (\ / : * ? " < > |) become “-”. Password-protected PDFs need the password removed first.

Split & Rename PDF — a real example made with this tool from sample files

Four pages of invoices → INV-1001, INV-1002 and INV-1003, split where each invoice starts.

How to use the PDF split-and-rename tool — 4 steps

  1. 1

    Add the PDF. Its text is read on your device (scanned pages can be read with OCR).

  2. 2

    Choose where to split: where a page contains a word or label, at blank separator pages, every N pages, by bookmarks, by ranges or every page.

  3. 3

    Choose how to name the files: tap a “Label: value” found on page 1, or type a label — the text after it on each part becomes {a}. Combine it with {n}, {file} or a second label.

  4. 4

    Check the table — pages, first-page thumbnail and name for every part — edit any name, then press Split & name and download the ZIP.

💡 Tip: Scanning a stack of separate documents? Put a blank sheet between them and choose “At blank separator pages” — the blanks are dropped automatically.

Split by content, not just page numbers

Ordinary splitters ask for page numbers. Real batches don’t have neat page counts: one invoice is one page, the next is three. Splitting where a page contains a label — “Invoice No”, “Statement period”, “Employee ID” — starts a new file exactly where each document begins. For complex cases, switch on advanced patterns (regular expressions).

Names that mean something

A file called “scan-part-7.pdf” is useless in a folder. Choose a label and the text after it on each part becomes the file name: “Invoice No: INV-1003” gives INV-1003.pdf; add “Customer” for INV-1003 Carter & Sons.pdf. Parts where the label isn’t found are marked so you can type a name, duplicates get (2), (3)…, and characters not allowed in file names are replaced. The ZIP includes split-summary.csv listing every part, its pages and its name.

Scanned pages and limits

Rules and names need text. If some pages are scans, press “Read scanned pages with OCR” — English OCR runs on your device, a few seconds per page — and the rules then see those words too. Each part is a new PDF with its pages copied as they are (text stays selectable).

Frequently asked questions

How do I split a PDF into separate files by text?

Add the PDF, choose “Where a page contains…” and type the word that appears on the first page of each document (for example “Invoice No”). Each match starts a new file.

Can it rename the split files automatically?

Yes. Type a label such as “Invoice No” — the text after it on each part becomes the file name. You can combine two labels and the part number, and edit any name before saving.

Can I split at blank pages?

Yes. Choose “At blank separator pages”. The blank pages are removed from the results.

Does it work with scanned PDFs?

Yes — press “Read scanned pages with OCR” first so their words can be found (English).

Can I split by bookmarks?

Yes, when the PDF has bookmarks: one file per top-level bookmark, named from the bookmark with {title}.

Is my PDF uploaded?

No. Splitting and naming happen in your browser on your device.
