A free PDF reader that's impressively quick
FoxIt Reader itself is safe to use in its current version; older versions installed additional, potentially unwanted software. FoxIt has partnered with Ask, and for many versions the Default installation settings have included Ask's browser toolbar.
FoxIt Reader is free. Other FoxIt software, including other PDF software, may be free or paid, depending on the software in question.
FoxIt Reader is available for Windows on desktop, and several mobile platforms including Android and iOS. The desktop and mobile versions of the software are very distinct and have different features; the questions and answers here pertain to the Windows desktop version.
FoxIt Reader comes packaged in an automatic installer, like many modern applications. While installing it, you will have the option of using Default or Custom settings. Use Custom settings if you want to install an additional language or remove other software bundled with the reader. Otherwise, the Default settings are appropriate for most users.
The application itself does not come bundled with a user manual. Help and support for all of FoxIt's software can be obtained online from their website.
FoxIt updates its software regularly, usually more than once per year, but the company does not always adhere to a fixed release schedule. Updates are most common when many users ask for particular features, or for features in the newest versions to be removed. It is recommended to check periodically to see if Reader, or any FoxIt software, has been updated since last installation.
If you did not install a language pack during installation, you will need to use the software's official website to download an XML language file. Then, place the XML file in the appropriate directory (by default: CProgram Files or Program Files (x86) Foxit SoftwareFoxit Readerlang), open FoxIt Reader, and change to the new language under Preferences.
Some PDF files disallow commenting, and by extension highlighting text. Under File -> Properties, you can check Security to see if this is the case. Otherwise, a PDF you are viewing may simply be scanned, with no computerized text that the reader can recognize. You also cannot copy text from PDFs of either type.
To update FoxIt Reader, you must remove the previous version. Newer versions cannot install over an existing version. On Windows, this is as simple as removing the software via the Control Panel, then starting installation of the new version again.
Foxit Reader is not intended to delete pages by itself. You can remove pages from a document with FoxIt Reader PDF Printer, by removing the pages you do not want and using the Print to PDF function. However, this cannot save form fillable PDFs.
