How to split a PDF

1) Split by Range

1. Open the Range tab.
2. Add one or more ranges (e.g., 1-3, 7, 10-end). Ranges are inclusive.
3. (Optional) Check “Merge all ranges into one PDF” to receive a single combined file.
4. Click Split by range to download.

2) Split by Pages (picker)

1. Open the Pages tab.
2. Choose Extract all pages or switch to Select pages and tick the thumbnails you need.
3. Click Split by pages to save each page to its own PDF (or a ZIP if multiple files).

3) Split by Size

1. Open the Size tab.
2. Enter a maximum size per file (KB or MB). The tool packs pages into parts up to ~that size.
3. Click Split by size to export a ZIP with numbered chunks.
