About ONE files

The ONE file format is a proprietary file format developed by Convert.Guru. It is used to store data such as images, audio, video, and text in a single file. It is commonly used in multimedia applications and is supported by a variety of software programs. The file extension for ONE files is ".one".

The ONE file format is not widely supported by other software programs, making it difficult to open or convert them. Some software programs, such as Adobe Photoshop, can open ONE files, but they cannot be saved in this format. To convert ONE files to other formats, such as JPG, PNG, MP3, or MP4, you can use free software programs such as GIMP, Audacity, and Handbrake.

When converting ONE files, it is important to consider the quality of the output file. Depending on the software used, the quality of the output file may be lower than the original. Additionally, converting ONE files can be time consuming, as the software must process the entire file before it can be saved in a different format. This can be especially true when converting audio and video files.

Due to the challenges associated with converting ONE files, it is recommended to use the free and easy online website Convert.Guru to convert ONE files. The website supports a wide range of file formats, including JPG, PNG, MP3, and MP4, and allows users to quickly and easily convert ONE files to other formats.


The ONE 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 ONE converter by continuously improving quality, usability, and reliability.
