浏览器内运行这个工具能做什么
Select one PDF, then extract selected pages into one file or split it into individual pages, custom range files, or every N pages. Results are reopened before download and multi-file output is packaged as ZIP. Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint.
Extract mode preserves the first requested occurrence of each page, including reverse ranges such as 5-1; duplicate page selections are ignored.
Processing runs in the current browser tab. Every generated PDF is reopened and checked before its download is enabled, while practical limits still depend on browser memory and document complexity.
这个工具可以完成什么
Pull one chapter out of a large book or manual, then share the extracted file instead of the original whole document.
Split a multi-invoice PDF into individual files — one per client — for billing and record-keeping.
Extract just the signature page from a contract PDF to send for signing without revealing confidential terms.
依赖结果前需要检查什么
- Performance and maximum practical input size depend on browser memory, device speed, and the structure of the input.
- Review the generated result before replacing or publishing an original file.
如何使用
- 1
Add the single PDF file you want to split.
- 2
Choose Extract one PDF, Each page, Range files, or Every N pages, then enter the page recipe required by that mode.
- 3

使用场景
Pull one chapter out of a large book or manual, then share the extracted file instead of the original whole document.
Split a multi-invoice PDF into individual files — one per client — for billing and record-keeping.
Extract just the signature page from a contract PDF to send for signing without revealing confidential terms.
Split a large scanned batch into individual files when multiple documents were scanned together by mistake.
Split a presentation or report into individual page PDFs for use as standalone slides or exhibit attachments.
使用技巧
Enter ranges like '1-3, 5, 8-12'. Extract mode keeps the requested order, reverse ranges run backward, and duplicate selections keep only their first occurrence.
If you only need a few pages from a large PDF, split out the relevant section first, then compress it — much faster than compressing the whole file.
Page numbers printed on a document may differ from the actual PDF page numbers. Use a PDF viewer to confirm the correct page positions before splitting.
To turn a 10-page PDF into 10 separate one-page PDFs, use 'Split every page' mode instead of specifying ranges manually.
常见问题
How does PDF splitting process my file?
Splitting happens in your browser. Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint.
Can I extract a range of pages instead of splitting the whole file?
Yes. Extract one PDF mode accepts comma-separated pages and ranges such as '3-7, 10, 15-12'. The result keeps requested order and ignores duplicate selections after their first occurrence.
What happens to the original PDF after splitting?
Nothing. The original file is not modified. Splitting creates new files from a copy of the selected pages.
Can I split a PDF with owner restrictions?
Encrypted PDFs and permission-restricted PDFs are not supported by the current browser engine. Use a trusted desktop PDF tool to create an unencrypted copy before splitting.
Is there a page limit for splitting?
The practical page limit depends on available browser memory, document complexity, and device performance. Split large documents in representative batches when possible.
Can I split a PDF every N pages?
Yes. Use the Every N pages mode and specify how many pages each generated file should contain.
Does splitting reduce the quality of extracted pages?
Page content is copied without intentional rasterization, but each output is a newly serialized PDF. Document-level structures such as metadata, outlines, forms, signatures, annotations, and shared resources may change or be omitted; verify each result.
Can I select non-consecutive pages?
Yes. Enter page numbers separated by commas, for example: '1, 4, 7-9, 12'.
