The Split PDF tool in PDFbat with a document loaded and the split mode options open

Five ways to split, one simple tool

Splitting sounds simple until you need it a particular way. Sometimes you want every page on its own, sometimes you need chapters, and sometimes a portal will only take files under 5 MB. PDFbat Split PDF covers all of these with five modes, and every resulting file is a normal PDF with the original pages copied across untouched.

The parts are named after the original file and the pages they contain, for example report_1-3.pdf and report_4-7.pdf, and delivered together as a single ZIP so nothing gets lost.

Why split with PDFbat

Five split modes

Every N pages, custom ranges, every page, by maximum file size, or odd and even pages. Pick the one that matches the job.

Split by file size

Set a limit such as 5 MB and PDFbat packs as many pages as fit into each part, then checks every part against the limit.

Tidy ZIP download

All parts arrive in one ZIP with clear names that show which pages each file holds.

Pages copied untouched

Text stays searchable, links and images stay as they were. Nothing is re-rendered or recompressed.

Saved to your Drive

The ZIP is stored in your private Drive, so you can download it again later from any device.

Every split mode explained

Every N pages: The default. Set Pages per file to cut the document into equal chunks, for example 2 for two page forms or 10 for long batches of scans. The last part holds whatever is left over.
Custom ranges: Type ranges separated by commas, one file per range. 1-3, 4-7, 8- makes three files, and a range left open at the end, like 8-, runs to the last page. You can also use last, as in 10-last.
Every page: Turns a 20 page PDF into 20 single page PDFs. Handy for separating scanned letters, certificates or invoices that were scanned in one batch.
By max file size: Enter a size in MB, such as 5 or 9.5. Pages are grouped in order until the next page would push the part over the limit. Each part is then saved and measured, and split again if shared fonts or images made it larger than estimated. A single page bigger than the limit stays on its own.
Odd and even pages: Produces two files, one with pages 1, 3, 5 and so on, the other with 2, 4, 6. Useful for manual duplex printing or separating front and back scans.
Clear file names: Each part is named after the original file plus its page numbers, such as contract_4-7.pdf, so you always know what is inside.

When to use each mode

Upload portals with a size cap: By max file size, set just under the portal limit.
Separating a batch scan: Every page, or Every N pages if each document is the same length.
Pulling chapters out of a book or report: Custom ranges, one range per chapter.
Printing double sided on a single sided printer: Odd and even pages, then print one file, flip the stack and print the other.
Sending only one part to someone: Use Extract Pages, which gives you one PDF with just the pages you pick.

Tips for splitting

Not sure where chapters start? Open the file in the PDF editor and check page numbers in the Pages panel first.
If parts are still too large even when split by size, the pages themselves are heavy. Run Compress PDF first, then split.
To put parts back together in a new order later, use Merge PDF.
Splitting a scanned book where each page shows two pages side by side? Split Pages in Half cuts each spread down the middle.

Frequently asked questions

How do I split a PDF into single pages?

Choose the Every page mode and click split. You get one PDF per page inside a ZIP file.

How do I write custom ranges?

Separate ranges with commas, one output file per range, for example 1-3, 4-7, 8-. A range with no end, like 8-, runs to the last page, and last also works, as in 5-last.

Can I split a PDF to stay under an upload limit?

Yes. Choose By max file size and enter the limit in MB. PDFbat checks each part after saving it and splits again if needed, so parts stay under the limit unless a single page is already larger.

Why do I get a ZIP file?

Splitting usually produces several PDFs, so they are bundled into one ZIP for a single download. Every operating system can open ZIP files without extra software.

Does splitting reduce quality?

No. Pages are copied as they are. Text stays selectable and images keep their original resolution.

What is the difference between Split and Extract Pages?

Split produces several files that together cover the document. Extract Pages produces one new PDF containing only the pages you pick.

Can I split PDFs automatically?

Yes. The PDFbat API runs the same split modes with 250 free calls a month.
