Native RTL Support, Now Built into WebViewer

Expand your software’s ability to render all RTL language content, with WebViewer UI localized into Arabic, Hebrew, Persian, and Urdu.

WebViewer now natively supports right-to-left (RTL) language content, making it easier to build applications that work seamlessly across global regions. In addition to full RTL content handling, WebViewer’s UI is now localized into Arabic, Hebrew, Persian, and Urdu, with more languages to follow.

Until now, RTL content was difficult to handle because PDFs lack implicit text direction. Developers often had to build custom workarounds that still produced issues like reversed character order, inaccurate search results, or broken copy/paste.

Now with native RTL support, WebViewer ensures all RTL language content now displays and behaves correctly. Users can leverage search, select, copy, and paste functionality as intended.

Key capabilities include:

RTL languages have nuanced formatting rules, so getting it “mostly right” isn’t enough. For instance, there can be multiple technical ways to display a word, but only one is contextually correct.

Without native RTL support, these details get lost, leading to broken workflows like inaccurate search, failed copy/paste, or mistranslations that frustrate users. Native speakers can easily spot the difference between high-quality rendering and a patchwork solution.

WebViewer’s new RTL support ensures that content meaning and context and preserved, so users can interact with documents naturally and intuitively.

With the fall release, users can perform everyday tasks seamlessly, and developers can ship globally ready products without costly workarounds.
