Split PDF online — PDFWhirl

What Split PDF does

Split PDF reads one source document and creates a separate PDF for each page range you define. A range can cover consecutive pages, and several ranges can be added to the same job.

The Pages mode produces one PDF per source page. Custom ranges preserve their page order inside each generated file.

How to use this tool

Upload one PDF
Select the document you want to divide and wait for its page preview to load.
Choose Range or Pages
Use Range to define one or more groups, or Pages to create a separate PDF for every page.
Set the page boundaries
For Range mode, enter the first and last page for each group and add another range when needed.
Split and review
Start the job, then download each generated output and confirm that the intended pages are present.

Common use cases

Separate chapters

Create individual files from chapter ranges in a longer manual or report.

Isolate an attachment

Pull an appended form or exhibit into its own document for a separate workflow.

Distribute pages individually

Convert a multi-page scan into one PDF per page when recipients need separate records.

Supported inputs

One PDF document (.pdf, application/pdf)
Custom page ranges or all-page splitting

Output

One or more PDFs named in sequence (split-1.pdf, split-2.pdf, and so on), with one output for each valid range or page.

Limitations to know

A range outside the available page count cannot produce the requested selection.
The current public tool splits by page range or by individual page; splitting to a target file size is not offered.
Empty selections and source PDFs with no readable pages cannot create output.
Document-wide navigation or interactive behavior should be checked after pages are separated.

Privacy and document handling

The source PDF is transferred to configured object storage before the split worker downloads it for temporary processing.
Each generated file receives its own stored output record and signed download link.
Because several outputs may be created, verify and manage every generated file rather than only the first download.

Stored input and output objects are deleted automatically: files uploaded without an account are removed about 24 hours after upload, and files belonging to a signed-in account are removed after 7 days. A scheduled sweep enforces this hourly against the object store itself. Workers attempt to remove per-job temporary directories after processing. This does not delete stored input or output objects.

Read the Privacy Policy and Security page for verified implementation details and open questions.

Troubleshooting

A requested range is missing

Check the displayed page count and make sure the range starts and ends on existing pages.

Too many files were created

Use Range mode instead of Pages mode and group consecutive pages into the same range.

The preview cannot load

Confirm the file opens as a normal PDF on your device and is not truncated or password protected.

Frequently asked questions

Can one page appear in more than one output?

Yes. Add overlapping custom ranges when the same source page is required in different generated files.

Does Split PDF remove pages from my original file?

No. It reads the uploaded source and creates new outputs; the original document on your device is not edited.

Can the tool split by megabytes?

No. The verified public implementation supports custom page groups and one-file-per-page output, not a target file size.

How should I check my Split PDF result?

Open every Split PDF download and compare it with the unchanged source before sharing or deleting anything. Pay particular attention to this documented limitation: A range outside the available page count cannot produce the requested selection.
