無料 PDF 分割ツールとは？

無料のオンライン PDF 分割ツール。PDF ファイルを複数に分割。ページ数や範囲を指定して抽出。ブラウザ内で完全処理、安全で無料。

Large PDF documents often contain more pages than you need — contracts with appendices, reports with cover pages, or scanned documents that include blank or irrelevant pages. PDF Splitter lets you extract only the pages you need by selecting individual pages or defining page ranges. The result is a new PDF containing only your selected pages.

Upload any PDF and use the visual page selection interface to choose which pages to keep. You can select individual pages with checkboxes, or enter page ranges using standard notation (1-3, 5, 7-9). Multiple ranges are supported in a single input: "1-5, 8, 10-12" extracts pages 1 through 5, page 8, and pages 10 through 12. Invalid page numbers are automatically ignored with a clear warning.

The tool handles PDFs of any size. All processing uses PDF-Lib running locally in your browser — your document is never uploaded to any server. This is essential for sensitive documents where privacy matters. The output PDF preserves the original formatting, fonts, images, and layout of the extracted pages.

Split a multi-chapter report into individual chapter PDFs. Extract only the signed pages from a contract. Remove blank pages from a scanned document. Create a sample document by extracting a few representative pages. The split operation is fast and produces a clean, well-formed PDF that works in any PDF reader.
