What is a PDF file?
The Portable Document Format (PDF) is a comprehensive file format, standardized as ISO 32000, designed to present documents consistently independent of application software, hardware, and operating systems. It encapsulates a complete description of a fixed-layout 2D document, including text, fonts, vector graphics, and raster images, based on the PostScript language. Advanced implementations support interactive form fields, JavaScript scripting, 3D objects (U3D/PRC), and various encryption standards.
How to open a PDF file
PDF viewing is natively supported by all major modern web browsers (Chrome, Edge, Firefox, Safari) and most operating systems via built-in previewers. For advanced manipulation, form filling, or pre-press validation, dedicated software such as Adobe Acrobat DC, Foxit Reader, or open-source tools like Ghostscript and Poppler is required.

What is a WMF file?
Windows Metafile (WMF) is a 16-bit graphics file format originally introduced in Windows 3.0 (1990) to store a sequence of Graphics Device Interface (GDI) function calls. Unlike pure bitmaps, WMFs contain instructions for drawing vector lines and circles, though they can also encapsulate raster images. The format suffers from device-dependence and lacks the color handling capabilities of its 32-bit successor, Enhanced Metafile (EMF), leading to its deprecation in modern development.
How to open a WMF file
Due to its legacy status, WMF is natively supported by the Windows Picture and Fax Viewer and Microsoft Paint. For professional editing and conversion, vector graphics software such as Adobe Illustrator, CorelDRAW, and Inkscape (using UniConvertor) is recommended. On Linux, the libwmf library enables support within the GIMP and ImageMagick suites.
