Split a PDF by text and name each file from its content

No. Your PDFs are read, split and named in your browser, on your device, and are never uploaded. Your browser blocks this page from connecting to the internet or loading anything from other websites. How this works.

Choose to split where a page contains a keyword, and enter the word or phrase that appears at the start of each document, such as Invoice No or Payslip. Each page where it appears starts a new file. You can search only the top lines or an area of the page, skip pages that contain another phrase, or use a regular expression for patterns such as INV-\d+.

Use the Payslips preset. It starts a new file whenever the employee changes and names each file from values such as the employee’s name or ID and the pay period. Payslips for the same employee that are next to each other are joined and flagged so you can check them. Guide: split payslips by employee.

Use the Invoices preset. It starts a new file when the invoice number changes, so multi-page invoices stay together, and names each file from values such as the invoice number and customer. Guide: split invoices by number.

Yes. Pages without usable text are detected and read with OCR on your device. Choose the language of your documents: English, Hindi, Spanish, Portuguese or French, or a combination. The wrong language gives confident but wrong results. Uncertain words are highlighted for you to review. Guide: scanned PDFs and OCR.

Many statements and invoices print “Page 1 of 3”, “Page 2 of 3” and so on. The preset starts a new file at every “Page 1 of …”, so each document keeps all its pages, even when page counts differ.

Yes. Choose the bookmark level to split at, optionally only bookmarks whose title contains certain text, and use the bookmark title in the file name.

Yes. Split every N pages, for example every 2 pages for two-page forms, by ranges such as 1-3, 4-10, or by choosing the pages yourself. Every split can be corrected by hand before you download.

Yes. Enter the password when asked; it is used only on your device and is never stored. By default, the split files are protected again with the same password to open them and the same permissions; if you didn’t enter the owner password, you choose a new one for the split files. If the PDF’s owner has restricted page changes, you need the owner password to split it.

Splitting a signed PDF always invalidates its digital signatures, because a signature covers the whole original file. The tool warns you first, removes the signatures from the split files and records this in the audit report. The split files are not signed, so keep the original if you need the signed version.

For the pages in each file, yes: links, form fields, bookmarks, page labels, layers and accessibility tags are carried over. Links to a page that ends up in another file are removed by default; you can choose to point them to that file instead. Each change is listed in the audit report. Document scripts are never copied, and attached files are copied only into a split file you choose.

There is no usage cap and no paid page limit. The practical limit is your device’s memory, so the tool has a size and page limit for each kind of device and tells you before processing if a file is over it. Computers handle much larger files than phones.

The audit report (_split-audit.csv) lists every split file with its original pages, its name, the values used and where each came from (text, OCR, a bookmark or typed by you), any flags, and the result of the checks. It is written in English whatever the interface language, so reports can be compared and archived.

Yes. Save your rule and file name pattern as a template. Templates are stored only in this browser and contain rules, patterns and page areas, never text or pages from your documents. You can also export a template as a file to share with colleagues.

Not with its built-in Split command, according to Adobe. In an Adobe Community thread from August 2026, Adobe’s Community Manager answered that Split can’t split by keyword and suggested page counts, bookmarks or custom JavaScript instead. This tool splits by keyword, pattern or changing value directly. PuffinKit is not affiliated with Adobe.

Yes. There is no sign-up, no watermark and no limit on how many PDFs you split.

No. You can use this tool without signing up.
