온라인으로 PDF 분할하는 방법 — 무료 단계별 가이드

There are five distinct split operations, each suited to a different scenario:

1. **Split by page range** — extract pages 1–10 from a 50-page document. Best for sharing specific chapters or sections.

2. **Split into individual pages** — create one PDF per page. Best for converting scanned multi-page documents into individual files.

3. **Split every N pages** — divide a 60-page document into files of 20 pages each. Best for batch processing or printing.

4. **Split by bookmarks** — divide at each chapter/section bookmark. Best for ebooks, reports, and documents with a table of contents.

5. **Split by file size** — divide until each output file is under a target size (e.g., 10 MB). Best for meeting email attachment limits.

1. Go to the WhiskFile Split PDF tool.

2. Upload your PDF. Files up to 50 MB are accepted on the free plan.

3. Select the split mode: "By page range", "Every N pages", or "Into individual pages".

4. Enter your page ranges. For example, enter "1-5, 6-20, 21-end" to create three output files.

5. Click "Split PDF". The results download as a ZIP file containing each section as a separate PDF.

1. Go to the WhiskFile Split PDF by Bookmarks tool.

2. Upload your PDF. The tool will detect and list all bookmarks (chapter titles, section headers) in the document.

3. Select which bookmarks to split on — by default, all top-level bookmarks are used as split points.

4. Click "Split by Bookmarks". Each section between two bookmarks becomes a separate PDF file, named after the bookmark text.

1. Go to the WhiskFile Split PDF by Size tool.

2. Upload your PDF and set the target size limit (e.g., 10 MB to fit Gmail attachments with room to spare).

3. The tool divides the PDF into chunks, each under the target size. It splits on page boundaries — it will not split in the middle of a page.

4. Download the ZIP file containing all parts, numbered sequentially (part-1.pdf, part-2.pdf, etc.).
