Split PDF

Split mode

Every page creates one file per page. Custom ranges creates a file for each entered range. Same number of pages per file makes equal-sized sections, with a shorter final file if needed. Odd pages or Even pages keeps only that group. Split after pages uses your chosen boundaries. At each bookmark starts a file at each supported page-linked bookmark; it needs bookmarks in the source.

Pages (leave blank for all)

In Custom ranges, enter separate sections such as 1-3,4-6. In Split after pages, enter the page boundaries.

Pages per file

Set the size of each section when splitting by a fixed page count; the last file can be shorter.

Keep bookmarks

Keep supported navigation entries whose destinations remain in each output.

Make form entries permanent

Shown when a PDF has interactive form fields. Keep the visible answers while making them uneditable in the new file. Digital signatures will no longer verify; keep the signed original.

Undo and Redo

Step backward or forward through workspace changes before saving. Your original PDF is not overwritten.

Jump to page and Thumbnail size

Use Go to find a page preview, or resize the previews for easier inspection. These controls do not change the saved page size.

All, None, Odd, Even and Select range

Select a group of previews, or enter numbers such as 1,3,5-10 and click Select. These select previews for inspection; Split mode and the Pages field determine the output sections.

PDF documents. An opening password is required when the file needs one to be read.

Local tests used synthetic 10, 50, 100 and 200 MB PDFs containing large images. Chromium, Firefox and WebKit: completed 10, 50, 100, 200 MB.

Chromium, Firefox and WebKit: completed 50, 300, 1000 text pages. The split tests created two range files, not one file per page.

Split PDF was tested on a 16 GB Mac with Chromium, Firefox and WebKit. These are observed examples, not guaranteed limits on your device. WebKit tests do not replace a check in Safari on your own device.

Choose your PDF, set Split mode to Every page or Custom ranges, then click Split PDF and download the files or a ZIP.

Splitting selects pages rather than lowering image quality. It does not use the image compression presets. The sizes of the resulting files depend on which pages and shared resources they contain.

Use Split PDF when you want separate documents. Use Extract pages when you want selected pages in one new PDF. To discard unwanted pages while keeping the rest, use Remove pages.

Yes. Choose Same number of pages per file in Split mode, then set Pages per file. The last file may have fewer pages.
