PDF File Converter

PDF files use a structured format that includes objects like text streams, images, and fonts, all compressed into a single file. They often rely on the PostScript language as a foundation for describing page layouts. The file supports different compression algorithms and encryption options to secure the content, and it uses a cross-reference table to quickly locate objects within the file.

One interesting fact about PDF files is that they became an open standard in 2008, which helped expand their usage beyond Adobe’s software. PDFs are commonly used for official documents, ebooks, and forms because they maintain the exact layout and appearance intended by the creator. Many browsers now support viewing PDFs natively, making access even easier.
