To split a PDF into separate files, divide its pages into fixed-size groups or custom ranges, then download each group as its own PDF. This workflow creates multiple standalone documents; it does not create a split-screen view, combine pages onto one sheet, or simply reorder the source file.
The free, browser-based Split PDF tool works from one source PDF. It reads the document locally, reports its exact page count, and offers two ways to divide it: Every N pages or Custom ranges. Nothing is uploaded, and no signup is required.
The key is to plan around the finished files you need. A batch of receipts may require one PDF per page, while a report may need separate chapter files, an appendix, or a single-page summary. Decide on the output pattern first, then translate it into page groups.
Choose a split method that matches the output
Every N pages is the straightforward choice when the source document should be divided into predictable, consecutive groups. Enter the number of pages that belong in each file. The last file contains the remaining pages when the total is not evenly divisible by that number.
| Output you need | Split mode | What the tool creates |
|---|---|---|
| One PDF for every page | Every N pages with N set to 1 | A separate PDF containing each individual page |
| Roughly equal sections | Every N pages | Consecutive groups of the selected size, with any remainder in the final file |
| Specific chapters or sections | Custom ranges | One PDF for each range entered |
| One isolated page | Custom ranges with a bare page number | A PDF containing that single page |
Custom ranges give you more control over the boundaries. They are useful when page groups are not equal in length or when the deliverable is defined by a project, chapter, appendix, invoice, or exhibit rather than by a fixed count.
Split one PDF into separate files
- Browse for the source PDF. Click Browse PDF and choose the single PDF you want to divide. The tool reads it locally and displays its exact page count.
- Select a split mode. Choose Every N pages to create equal consecutive groups, or choose Custom ranges to define each group by page numbers.
- Define the groups. For Every N pages, enter how many pages should go into each output. For Custom ranges, type the ranges you want, separated by commas. Page numbers are counted from 1, and both ends of a range are included.
- Run the split. Press Split PDF. The resulting files appear in a list with their page ranges and file sizes.
- Download each part. Use the individual download link beside every output. The parts download separately without a ZIP archive, and their names are generated from the source filename and page range.
Keep the page count visible while choosing your split settings. It gives you the document’s actual final boundary, which is especially helpful when a file has been scanned, combined, or trimmed and its page numbering may not match your expectation.
Set page ranges without gaps or overlap
Custom ranges are entered in the same page-numbering system shown by the tool: 1-based and inclusive. For a 10-page PDF, for example, enter 1-3, 4-6, 7-10 to create one PDF for each listed group of pages.
A bare page number selects that page alone. If a range extends beyond the document, the tool clamps it to the real page count. Clearly invalid text is skipped instead of crashing the tool, so review the entered ranges before splitting rather than assuming every character was interpreted as intended.
For a complete division, make the ranges meet without gaps or overlap. If you need every page in a new file, plan the ranges from the first page through the last and check the displayed total. If the goal is only to isolate particular material, leave unrelated pages out deliberately rather than creating extra outputs for them.
Download and inspect each PDF part
Splitting creates separate outputs, not one combined document. Each result has its own row, page range, file size, and download link, allowing you to save only the files you need. There is no need to unpack a single archive after the split.
- Check that the listed page range matches the section you intended to create.
- Open each downloaded PDF and confirm that it starts and ends with the expected pages.
- Look for any pages that belong to a different group and adjust the ranges before repeating the split.
- Use the displayed file size as a quick reference, but verify the content rather than relying on size alone.
The original pages are copied losslessly into each output. Text remains selectable, embedded fonts are retained, vector graphics stay sharp, and image quality is untouched because the tool copies the source page objects without re-rendering or re-compressing them.
Match the split pattern to the finished task
The two supported modes cover many everyday document jobs, but the best choice depends on how the resulting files will be used. Consider whether the recipient needs equal chunks, document-specific sections, or a page-by-page set.
| Source document | Recommended mode | Practical result |
|---|---|---|
| A scanner batch containing receipts or forms | Every N pages with N set to 1 | Each page becomes an individual document for separate filing |
| A long report that needs regular sections | Every N pages | The report becomes consecutive, similarly sized files |
| A bound report with chapters, an appendix, and a summary | Custom ranges | Each logical section becomes a separate PDF |
| A bundle containing one important exhibit | Custom ranges with a bare page number | A new PDF contains only the selected page |
Equal page-count groups are convenient for distributing or archiving long material, while custom ranges are better when recipients need specific sections. In either case, the generated filenames preserve the connection to the source document and make the downloaded parts easier to identify.
Understand the privacy and file-protection limits
Processing happens locally inside the browser. The PDF is read and split in memory, so it does not leave your device, wait in a cloud queue, or remain stored on a remote machine after you close the page. This local workflow also requires no plugin, desktop program, or account.
- The tool supports modern desktop and mobile browsers, including Chrome, Edge, Firefox, and Safari.
- Once the tool page has loaded, the splitting workflow can run fully offline.
- Every output remains a separate downloadable PDF rather than a page-layout view or combined sheet.
- Automatic filenames use the source name and page range, so manual renaming is not required for basic organization.
Password-protected PDFs must be unlocked first
Encrypted or password-protected PDFs cannot be split until their protection is removed. The tool deliberately refuses to bypass encryption. Unlock the document in your PDF reader, then select the unprotected copy in the splitter and follow the same workflow.
Plan the groups against the displayed page count, run the split, download every intended output, and inspect the files before sharing them. The tool handles the separation locally, while the responsibility for choosing accurate ranges remains with you.
