About OPF files
OPF (Open Packaging Format) is a file format used to package multiple files together into a single file. It is commonly used to package e-books, but can also be used to package other types of digital content, such as audio, video, and software. OPF files are XML-based, and are typically compressed using ZIP or GZIP. OPF files are usually associated with the EPUB format, but can also be used with other formats, such as MobiPocket and FictionBook.
OPF files can be converted to other formats using software such as Calibre and various tools. These programs can convert OPF files to formats such as EPUB, MobiPocket, PDF, HTML, and TXT. However, conversion can be difficult due to the complexity of the OPF format, and some features may not be preserved during the conversion process. Additionally, some software may not support certain features of the OPF format, such as embedded fonts or images.
For these reasons, it may be preferable to use a free and easy online website such as Convert.Guru to convert OPF files. Convert.Guru supports a wide range of file formats, and is able to quickly and easily convert OPF files to other formats such as EPUB, MobiPocket, PDF, HTML, and TXT.
The OPF Converter Story
The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.
When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.
Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best OPF converter by continuously improving quality, usability, and reliability.
