In computing, Poppler (or libpoppler) is a free software library used to render PDF documents. Its development is supported by freedesktop.org. It is the most common such library on GNU/Linux systems, and is used by the PDF viewers of the open source GNOME and KDE desktop environments.
The project was started by Kristian Høgsberg with two goals in mind:
- To provide PDF rendering functionality as a shared library, in order to centralize maintenance effort
- To go beyond the goals of Xpdf, and integrate with functionality provided by modern operating systems
As of the version 0.18 release in 2011, the poppler library represents a complete implementation of ISO 32000-1,[not in citation given] the PDF format standard, and is the first major free PDF library to support its forms (only Acroforms but not full XFA forms) and annotations features.
PDF applications using Poppler

Poppler can use two back-ends for drawing PDF documents, Cairo and Splash. Its features may depend on which back-end it employs. A third back-end based on Qt4's painting framework "Arthur", is available, but is incomplete and no longer under active development. Bindings exist for Glib, Qt3, and Qt4, that provide interfaces to the Poppler backends, although the Qt3 and Qt4 bindings support only the Splash backend. There is a patchset available to add support for the Cairo backend to the Qt4 bindings, but the Poppler project does not currently wish to integrate the feature into the library proper.
Some characteristics of the back-ends include:
- Cairo: Anti-aliasing of vector graphics, and transparent objects.
- Splash: Supports minification filtering of bitmaps.
Poppler comes with a text-rendering back-end as well, which can be invoked from the command line utility
pdftotext. It is useful for searching for strings in PDFs from the command line, using the utility
grep, for instance.
