关于此 拆分 PDF 工具
Split PDF extracts exactly the pages you need from a larger document and saves them as a new PDF. Type a page selection such as 1-3 for a range, 5 for a single page, or 8-z to take everything from page 8 to the end (z always means the last page, so you never need to know the page count). Common uses include pulling one signed page out of a contract, separating chapters of a long report, extracting an invoice from a combined statement, or removing cover pages before sharing. The original upload is never modified - the tool builds a fresh PDF containing only the pages you selected, with the original quality, fonts and formatting intact because pages are copied, not re-rendered.

Split PDF vs. Merge PDF vs. Delete pages
Split PDF takes pages out of one document, which also works as a way to delete pages: to remove page 5 from a 10-page file, extract 1-4,6-z and the result is the same document without page 5.
Merge PDF is the reverse operation - it combines several PDFs into one. The two tools work well in sequence: split several documents down to the pages you need, then merge those pieces into a single file.
If you need to reorder or rotate pages visually instead of by number, the PDF Editor gives you a page-by-page view.
Typical page selections
First page only: 1 - useful for extracting a cover sheet or summary page.
Everything except the first page: 2-z - removes a cover letter or fax sheet.
One chapter: 12-24 - pulls a section of a long report or e-book.
Scattered pages: 1,4,9-11 - collects specific exhibits or signed pages into one file.
常见问题
How do I enter a page range?
Use formats such as 1-3 for a range, 5 for a single page, or combine them with commas like 1-3,7,10-12. The letter z means the last page, so 8-z extracts from page 8 to the end without needing to know the total page count.
Does splitting reduce the quality of my PDF?
No. Split PDF copies the selected pages directly into the new file rather than re-rendering them, so text, images, fonts and vector graphics keep their exact original quality.
Can I extract just one page from a PDF?
Yes. Enter a single page number such as 4 and the tool creates a new one-page PDF containing only that page.
Does splitting change or delete my original PDF?
No. The tool always creates a new PDF from the selected pages. The file you uploaded stays exactly as it was.
Can I split a password-protected PDF?
Not directly. Remove the password first with the Unlock PDF tool (you need to know the password), then split the unlocked file.
Is Split PDF free and watermark-free?
Yes. Splitting is free, requires no account, and the output PDF has no watermark added.
我上传的文件是私密的吗?
Files are stored under unique temporary names only while the split runs, and temporary files are cleaned automatically within a few hours.
