What is HTM file format?

The HTM file format is a file format used for hypertext documents. It is similar to HTML but has additional features that make it more suitable for web-based applications, particularly for documents that include graphics, audio, and video. HTM files are written in HyperText Markup Language (HTML), a coding language for webpages.

The HTM file format allows for the use of advanced formatting and styling elements, such as tables and images, that are not supported by HTML. HTM files may also include scripting language, such as JavaScript and VBScript, and other languages such as C++, PHP, and Java.

HTM files have several advantages over HTML, including the ability to carefully control the look and design of a web page, and the possibility of incorporating interactive features. They are also more reliable than HTML as they are less likely to become corrupted or to display incorrectly in a web browser.

HTM files can be opened using any web browser, as long as it supports HTML. They can also be opened with HTML editors and other text editors, such as Notepad or TextEdit.

What is PDF file format?

PDF (Portable Document Format) is a widely used document file format developed by Adobe Systems in 1993. It was specifically designed to provide a platform-independent solution for storing and sharing documents across various operating systems and over the Internet. PDFs utilize a vector-based drawing model, storing graphical elements such as lines, shapes, and images as mathematical equations. This unique approach ensures that PDFs are resolution independent, guaranteeing consistent document quality regardless of the viewing device or program.

One of the key advantages of PDFs is their support for a range of security features. Encryption, password protection, digital signatures, and document watermarking are among the security measures available. These features make PDFs highly secure and suitable for sensitive documents, such as medical records, legal documents, government forms, and invoices. The printing industry also heavily relies on PDFs to facilitate electronic communication with customers.

Creating PDFs is a straightforward process, as they can be generated from various electronic document formats, including Word documents, PowerPoint presentations, and webpages. It’s important to note that PDFs are typically not editable directly. To modify the content of a PDF, it must first be converted to a different file format that supports editing. Numerous software programs, many of which are freely available for download, offer the functionality to convert PDFs to editable formats.

PDFs have gained immense popularity and have become a standard method for document sharing due to their versatility, security features, and consistent formatting. Their compatibility across different devices and operating systems ensures seamless document access for users. Additionally, PDFs preserve the layout, fonts, and images of the original document, making them an ideal choice for sharing visually rich content.
