Create new PDF files in a few minutes with CocoDoc’s impressive visual reorder tool. Its simple and effective function allows an easy rearrangement of files through efficient drag and drop. CocoDoc offers an effortless process of reordering and rearranging PDF files. The service can be adequately consumed with very little input. There is no need to download additional software for its execution. CocoDoc is an online service and can be easily accessed via any device or platform.

The platform covers the complete process in a perfectly secure manner. After the user is done with the work, CocoDoc does not keep any files within its servers. CocoDoc does not call for installing the platform across any device, hence taking up disk or memory space. This PDF organizer processes all its files across its cloud service and opens up the files directly through it. The application is contained across the cloud and is always up-to-date when accessed. The user would always be provided with the latest version of the tool without the need for lengthy updates.

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.

Recognition was accurate, except on some small text. This feature is available in the free version of the viewer and the editor. No watermarks are added when using it. Scanned PDF files can be deskewed before using the OCR feature, which improves recognition. I successfully used this feature to deskew a scanned PDF of a book in Burmese. Although the Burmese text is obviously not recognised by the OCR engine (that would be too much to expect), it still managed to deskew the Burmese text, while the header in English text became skewed. Custom search engines can be added, manually sorted, or deleted. The last used search is shown on the context menu, with other searches being available on a submenu. To add a custom search, search for the word “TEST” in your desired search engine, copy the URL and paste it into the New search dialog from Preferences, Search Providers, New…
