The split tool creates a new PDF containing only the pages you specify. It is intended for extracting a chapter, selected evidence, or a small handout from a larger file without modifying the original. Page selection uses physical PDF page positions, beginning at 1, which can differ from printed page labels such as roman-numeral front matter.
After upload, the server validates a range made from numbers, commas, hyphens, and spaces. A pattern such as 1-3, 5, 7-10 requests several inclusive ranges and single pages. The split script collects the requested page positions, removes duplicates, sorts them into ascending document order, and writes one new PDF. The result is not a folder of separate one-page files, and the expression cannot be used to reorder pages. The interface does basic syntax checking, while out-of-range or structurally damaged input can still fail during processing.
A student can extract assigned reading pages from a large course pack for personal annotation while preserving the complete source file.
A case worker can prepare a permitted excerpt from a longer packet, then review that no unrelated personal records remain in the output.
Only page selection is performed. The tool does not redact hidden text, remove metadata, rewrite internal references, or certify that omitted information cannot be inferred. Requested pages are sorted into ascending source order and duplicate selections are collapsed, so entries such as 5,1,3 or repeated page numbers do not preserve the typed sequence. Forms, bookmarks, page labels, attachments, and digital signatures may not carry over correctly; signed PDFs can lose signature validity. Page numbers beyond the document length will fail. Use a dedicated redaction application when information must be irreversibly removed.
The source and extracted PDF are uploaded to private server storage. The temporary download expires after one hour, and the cleanup process deletes uploads and outputs older than one hour. An excerpt may still contain confidential headers, metadata, or embedded content, so inspect it with an appropriate PDF viewer before sharing and follow your organization’s disclosure procedure.
