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 BMP file?

The BMP (Bitmap) format, formally known as the Device Independent Bitmap (DIB) file format, is a raster graphics standard developed by Microsoft for the Windows operating system. The file structure consists of a file header (BITMAPFILEHEADER), an information header (typically BITMAPINFOHEADER), a color table, and the pixel array. Data is stored as a grid of pixels with color depths ranging from 1-bit to 32-bit, typically uncompressed, though the format supports lossless Run-Length Encoding (RLE4 or RLE8) and Huffman 1D compression for specific bit depths.

How to open a BMP file

Due to its simplicity and documentation as a core Windows standard, BMP files possess near-universal compatibility. They can be opened natively by virtually all image viewers and web browsers across Windows, macOS, and Linux without additional software. Standard utilities include Microsoft Paint, Apple Preview, and Windows Photos. For advanced manipulation, pixel-based editors like Adobe Photoshop and CorelDRAW are recommended, though the format is rarely used for complex editing due to its large file size.
