Split one PDF into separate files
Split PDF creates individual-page files, fixed-size page groups, or one file for each custom range. A single result downloads as a PDF; multiple results are packaged in a ZIP archive.
Choose a split mode
Every page creates one PDF for each page.
Pages per file creates consecutive groups of the size you enter, with a smaller final group when pages remain.
Custom ranges creates one PDF for each comma-separated page or range, such as
1-3, 7, 10-12.
Custom ranges are produced in the order entered. Overlapping ranges are allowed when you intentionally need a page in more than one output, but an identical range cannot be entered twice.
How to split a PDF
Choose the document
Add one PDF and wait for its page count and document changes to be checked.
Choose the output groups
Select every page, enter pages per file, or provide the custom ranges you need.
Review changes
Acknowledge signature loss or a large operation when the page asks you to.
Split and download
Create the outputs, verify the number of files, then download the PDF or ZIP result.
Splitting copies visible pages into new documents. Form values can stay visible, but fields become non-editable. Bookmarks, attachments, accessibility structure, and valid digital signatures are not carried into the outputs.
Use Extract PDF Pages when you want selected pages combined into one new PDF. To put separate documents back into one ordered file, use Merge PDF.
Large document compatibility
The source PDF can be up to 50 MB. Very large page counts require confirmation, and generated split files stop at a combined 200 MB to avoid exhausting browser memory. Creating one file per page is usually heavier than creating a few larger groups.
Can I split every page into a separate PDF?
Yes. Choose Every page, and the individual PDFs will be downloaded together in a ZIP archive when there is more than one output.
How do custom PDF page ranges work?
Enter comma-separated pages or inclusive ranges such as 1-3, 7, 10-12.
Each entry becomes a separate PDF in the entered order.
Why did the split result download as a ZIP?
Multiple output PDFs are placed in one ZIP so the browser can download them together. A split that creates only one output downloads as a PDF.
What happens to forms, bookmarks, and signatures after splitting?
Form values may remain visible but fields become non-editable. Bookmarks, attachments, accessibility tags, and valid digital signatures are not preserved in the new files.
Are PDF files uploaded for splitting?
No. The document is inspected, split, and packaged in your browser after the page loads.
