A new software tool mixes pages of 2 or more PDF files and Insert Word, Excel or PowerPoint documents easily. With the rapid development of the Internet, people often use and manage a large number of PDF documents in their daily work. More and more users find that they often need to manipulate and adjust PDF pages, or insert some pages from one PDF file into another. Most of PDF editor programs are usually complex and overwhelm beginner users at first glance, especially if they just want to rearrange certain pages in the document or mix the contents of some PDF files. PDF Mixer simplifies these processes and provides a variety of methods for inserting and adjusting PDF pages. Unlike regular PDF tools, PDF Mixer is a powerful PDF page management and organization freeware tool which can mix and rearrange the PDF pages of 2 or more PDF documents, and add PDF pages to existing PDF files then save them to a new file. PDF Mixer also allows users to copy, rotate, delete, switch and merge PDF pages in multiple PDF files easily. In addition, it can insert blank pages and images, scan new pages from the scanner to PDF, and insert Word, Excel or PowerPoint documents into existing PDFs.

The professional and free versions are the same program. Features in the free version, such as adding comments and highlighting, can be used without any watermark being added. The professional features are also available in the free version, but documents are saved with a watermark until it is registered. A warning dialog is shown if you attempt to use the professional features in the free version. Either cancel the action, or don’t save the document to avoid adding watermarks. In the Viewer, security options can be changed in Preferences, in the Editor, they can be changed in Document Properties, Security. When a secure document is open in the Editor, a padlock icon is shown on the Tab Bar indicating that there are some restrictions on modifying the content. No preview thumbnail is shown for PDF files that need a password to be opened. Open the Search Pane to find text in the current document, all open documents, or documents in folders on your hard drive.

In my tests, PDF-XChange Editor is much faster than the latest Adobe Reader DC. My personal collection of PDF documents, some of which may contain the search string several times, while others may not contain it at all. Most of the test set doesn’t change. F) of multiple PDF documents as the menu on the right shows. The Proximity search lets the user specify whether to find only adjacent words, words in the same paragraph, page, or document. To highlight the first, second, and subsequent words in the search string that have been found, the Coloured Search Results option displays them in different colours. This may be overkill for ordinary users, but for those who have to trawl through large collections of PDF files it may be very useful. It’s certainly a big improvement on the Advanced Search in Adobe Reader, though the colours need some refinement. Shortcuts F4 and Shift F4 will find the next and previous search results. These can be customised if you prefer to use the Adobe Reader defaults of Ctrl G and Ctrl Shift G. Personally, I find F4 more intuitive since F3 and Shift F3 are used for find in page.

I never noticed the Adobe Reader shortcuts before. PDF-XChange can find ligatures used in OpenType fonts. There is an option in Preferences, Page Text to preserve ligatures on copy. If the checkbox is cleared, æ (for example) will be copied as ae. The Editor can read selected text using a computer generated voice with a male or female American accent, or a female British accent. It works well on standard English text, but it fails to recognise non-standard ligatures, and foreign words are hard to understand. K) and shortcuts can be assigned to "Read Select Text Out Loud" and "Stop Reading." I assigned shortcuts "r," and "Shift R" respectively for easy of use. The process takes a few minutes - perhaps 15 seconds per page - but the resulting document is then searchable without any obvious visible change to the document, and without much increase in file size. A typical 20 page PDF of 5.18 Mbytes was 5.4 Mbytes after OCR and saving as a new document.
