Split PDF
Extract selected pages into a new PDF file
Example: 1-3,5,8
Split PDF — what it does
Extract selected pages from a PDF into a new file using a range expression such as 1-3,5,8. It is the counterpart to deleting pages: instead of listing everything to remove, you name the pages worth keeping, which is far quicker when the extract is small.
When this tool helps
- Pulling one contract or chapter out of a combined document.
- Extracting the pages of a report that a specific recipient needs.
- Isolating a single form or certificate from a scanned bundle.
How to use it
- Choose the PDF file.
- Enter the page range to extract.
- Process the split.
- Download the extracted PDF.
Accuracy, limits, and good practice
- Page numbers count file positions, not printed page numbers — check the actual position of the first page you want before typing a range.
- Ranges and single pages combine freely, so 1,4-6,12 is a valid selection in one pass.
- For a bundle that needs breaking into many files at once, the odd-even splitter or a per-section extract may be quicker than repeated runs.
- Extracting is safer than deleting when you only need a few pages: what you did not name simply is not in the output, so nothing is destroyed by a typo.
Frequently asked questions
Does it change the original file?
No. A new document is created containing the pages you selected, and the source is untouched.
Can I extract into several separate files?
Run the tool once per range you want as its own file.
Are bookmarks and links preserved?
Page content transfers, but navigation elements that point outside the extracted range will no longer resolve.
Does the extract keep the original page size?
Yes, pages are copied with their dimensions intact, so a mixed-size document produces a mixed-size extract.

拆分 PDF能做什麼
用 1-3,5,8 這種範圍寫法，把 PDF 的指定頁面擷取成新檔。它是刪除頁面的對照做法：不必列出所有要刪的，只要指名要留的，當節錄範圍很小時快得多。
什麼時候用得上
- 從合併文件中抽出某一份合約或某一章。
- 只擷取特定收件人需要的報告頁面。
- 從掃描卷宗中分離單一表單或證書。
使用步驟
- 選擇 PDF 檔案。
- 輸入要擷取的頁面範圍。
- 執行拆分。
- 下載擷取出的 PDF。
精確度、限制與實務建議
- 頁碼指的是檔案位置而非印刷頁碼——輸入範圍前請先確認第一頁實際落在第幾頁。
- 範圍與單頁可自由混用，1,4-6,12 是一次即可完成的合法選擇。
- 若卷宗要一次拆成很多檔，用奇偶分離或依段落擷取，可能比反覆執行更快。
- 只需要少數幾頁時，擷取比刪除安全：沒點名的頁面就是不會出現在輸出中，打錯字也不會毀掉東西。
常見問題
會改到原始檔嗎？
不會。工具會建立只含所選頁面的新文件，來源檔完全不動。
可以一次擷取成多個檔案嗎？
每個要獨立成檔的範圍各執行一次即可。
書籤與連結會保留嗎？
頁面內容會轉移，但指向擷取範圍之外的導覽元素將無法對應。
擷取會保留原本的頁面尺寸嗎？
會，頁面連同尺寸完整複製，因此尺寸混雜的文件會產出尺寸同樣混雜的節錄本。
