Frequently asked questions
Can I extract several ranges into one file?
Yes. Enter ranges like “1-3, 8, 10-12” and tick “Merge all ranges into one PDF”.
What happens to bookmarks and links?
Page content, including links on the page, is preserved in each output file.
How do I split a PDF into separate pages?
Open the PDF, choose “Every page” and click “Split PDF”. Each page is saved as its own PDF, and the files download together as a ZIP.
How do I split a PDF by page ranges?
Choose custom ranges and type them with hyphens and commas: “1-3, 7, 10-12” gives one file with pages 1 to 3, one with page 7 and one with pages 10 to 12.
How do I split a large PDF into parts for email?
Choose a fixed size and enter a number of pages. The document is cut into equal chunks of that many pages, which you can send one at a time.
How are the split files named?
Each file is named after the original with its page range added, so you can tell the parts apart.
Are my files uploaded to a server?
No. ModifyPDF processes files with JavaScript inside your browser. Your documents never leave your device, and nothing is stored after you close the page.
Three ways to split
Custom ranges gives you one file per range, for example 1-3, 4-9 and 10-12. Fixed size cuts the document into equal chunks of N pages, which is handy for email size limits. Every page saves each page as its own PDF.
What you download
A single output downloads as a PDF. Several outputs are bundled into one ZIP, with each file named after the original and its page range so you can tell them apart. Tick “Merge all ranges into one PDF” to get the selected ranges as one document instead.
Typical uses
Separating a scanned batch into individual documents, sending only the relevant chapter of a report, breaking a large file into parts that fit an email or upload limit, or saving each invoice in a monthly statement as its own file.
Writing page ranges
Ranges are written with a hyphen and separated by commas: “1-3, 7, 10-12” means pages 1 to 3, page 7 and pages 10 to 12. Page numbers refer to the position in the file, which can differ from the numbers printed on the pages if the document has a cover or roman-numeral front matter.
