Fix garbled preview text (rendering engine)

Both the Merge and Split tabs include a built-in PDF preview. By default the program uses GDI+ rendering, but for some Chinese, Japanese and Korean text GDI+ can display garbled characters. If you see this, switch the rendering engine to PDFium.

  1. Open Settings

    Click the Settings button in the main window.

    Open the Settings window in PDF Merge and Split Pro

  2. Switch the rendering engine to PDFium

    In the General tab, open the rendering-engine drop-down, choose PDFium, then click OK.
