A 200-page report is awkward to email, and sometimes you only need three pages of it. Splitting a PDF cuts it into smaller documents so each person receives only what they need.
The Split PDF tool works locally in your browser: you choose page ranges, and the new files are created on your device.
How it works
Splitting is the reverse of merging: a new, smaller document is built from a selection of pages of the original. Because pages are copied rather than re-rendered, the text stays sharp and searchable. Page ranges are written with commas and dashes, so 1-3, 5 means pages 1, 2, 3 and 5, and 8-10 means pages 8, 9 and 10.
When this is useful
- Sending only the signed page of a long contract.
- Separating chapters of a textbook for different study sessions.
- Cutting a scanned batch into one file per document.
- Staying under email size limits by sending a long report in parts.
- Removing cover pages or appendices before sharing.
Step-by-step instructions
- Open the Split PDF tool and select your document.
- Enter the page ranges you need, separated by commas, for example 1-3, 5, 8-10, or choose to split into individual pages.
- Press split. The tool builds the new files and may package several of them into a ZIP archive.
- Download the result and open it to check the pages.
Tips for the best results
- Check the total page count first so that you do not enter a range beyond the end of the document.
- Use Extract Pages when you want a single new PDF made from selected pages.
- Use Organize PDF if you also need to reorder or rotate pages.
- Split very large files before converting them to Word or Excel to speed things up.
- Name the downloaded parts clearly so that you can find them later.
Common problems and how to fix them
The tool says the range is invalid
Check that the numbers are within the page count and that you used commas between ranges, for example 1-3,5,8-10.
The pages are in the wrong order after splitting
Pages follow the order you typed. Enter 5,1-3 if you want page 5 to come first.
The PDF will not open
It may be encrypted. Unlock it first with the password you know, or repair a damaged file with Repair PDF.
