Junko is a free tool that lets you split PDF files into separate documents by page range or number or combine many PDFs into larger files. By splitting large PDFs into multiple smaller files, you can work on just the pages or sections you need, and they're easier for small apps to handle. Combining multiple PDFs is useful for creating manuals and other multipage documents. Junko is powered by PDFsharp, the open-source .NET library of PDF wares.
Junko's interface is very basic and opens with a blank main view, but it's Aero-compatible and has a customizable toolbar. There are icons for opening files and accessing the product's Web page for feedback and support, but not much else. We clicked Open, browsed to a PDF file, and opened it in the main view. Junko displayed the document's individual pages as thumbnails. We right-clicked on one page and selected Save from the menu. We named the document, clicked Save, and then browsed to the target folder. We opened the new, single-page PDF in both Junko and Adobe Reader, and it was a perfect copy of the original. Combining several PDFs into one file was just as easy: Select the files, click Save, give the new document a name, save it, and the multiple documents appear as one multipage PDF file.
Some users may need to download and extract the free GhostScript thumbnail viewer (both 32-bit and 64-bit versions come in one download) to the Junko folder to see PDF thumbnails. You'll also need a compatible version of the Microsoft .NET Framework, but the Junko site can check your system automatically. This compact tool can help you handle PDFs more efficiently, and we recommend it to all users.
