PDF documents have been around for many years, becoming the standard format for storing and transmitting documents with rich content such as formatted text, images, tables, and other complex formatting. The format is still under development, with new features being added with each revision.
One of the reasons for its widespread adoption is its ability to store all the required document components, especially fonts, within a single file, allowing the document to be rendered equally on different platforms and devices.
PDF documents are read-only, unless opened within Adobe's own editing software. Support for importing and converting to and from the PDF format is widely supported by document editing software.
PDF files contain a sequence of unique bytes at the beginning of the file. This header section is usually followed by the main PDF file section. Where the header block is present, our document repair tool will parse the header data to validate the file type and also provide additional metadata that describes key characteristics of the document uploaded.
