Frequently Asked Questions
Select Extract mode, then type the page numbers or ranges you want (e.g., 1-5, 8, 12-15). The tool extracts only those pages into a new PDF file. Download it right away. To divide the whole file into multiple PDFs instead, use Ranges mode — each comma-separated group becomes its own file.
No. Pages are extracted as-is with no re-encoding. Resolution, fonts, images, and formatting stay exactly the same as the original. Need the reverse? Combine files with our Merge PDF tool.
No. All processing happens directly in your browser using pdf-lib and PDF.js. Your files never leave your device - fully private.
Yes. If your PDF has an open password, you will be prompted to enter it when you click Split. Owner-restricted PDFs (print/edit locks) can be split normally. Need to remove the password entirely? Try our Unlock PDF tool.
Yes. Use Split by Size mode and set the target to 5MB or 10MB (common email limits). The tool automatically divides the PDF into chunks that fit.
Auto-Split renders each page and detects blank or empty pages, then splits the document at those boundaries. Ideal for separating chapters or sections from scanned documents.
Yes. This tool replaces the Acrobat split workflow entirely — upload in your browser, pick one of 5 modes, and download the split files. No Acrobat install, no subscription, no account.
Use Every N Pages mode: enter N to cut the document into equal chunks (e.g. every 10 pages). For two or three roughly equal files, divide the total page count and use Custom Ranges mode with those boundaries.
Use Custom Ranges mode with two ranges: for a 10-page file enter 1-5 and 6-10 to get two separate PDFs. Each part downloads individually.
Yes. Use By Size mode and set a max size in MB — the tool packs pages into as many files as needed so each stays under the limit. Ideal for email attachments with per-file size caps.
