OPUS Audio Format

OPUS Converter

OPUS, or OGG OPUS, is a free and open source audio file format. Developed by Xiph.org foundation and later standardised by the IETF (Internet Engineering Task Force), it uses lossy compression to shrink files, while maintaining a high quality sound with minimal degradation. OPUS files are encoded with SILK or CELT codecs and use the OGG container format. Originally built for online media streaming, this file format is very practical for real-time interactive and audio-specific web streaming services with low delay (latency).

It is a very versatile file format, accommodating both high and low bitrates. That said, OPUS isn’t as widely used compared to more well-known audio file formats, being sidelined by other formats such as MP3 and WMA. Typical uses for OPUS files include web-based audio and video streaming, video conferencing, gaming, and radio broadcasting. OPUS files can be opened using compatible browsers such as Chrome, Firefox and Opera, but can’t be played by typical Mac media players or by Windows Media Players prior to the 2022 version. Alternative multimedia players such as VLC, FFmpeg or AIMP, however, do support the OPUS format.

PDF Document Format

PDF Converter

PDF stands for ‘Portable Document Format’ file. It was developed by Adobe so people could share documents regardless of which device, operating system, or software they were using, while preserving the content and formatting. The format has evolved to allow for editing and interactive elements like electronic signatures or buttons. The PDF format is now a standard open format that isn’t just available under Adobe Acrobat. It is maintained by the International Organisation for Standardization (ISO).

PDF files aren’t typically created from scratch, but are usually converted, saved or ‘printed’ from other documents or images before sharing, publishing online or storing. They can be viewed on almost all devices. Creating a PDF can involve compressing a file, making it take up less storage space. You would typically create a PDF if you wanted to ensure document fidelity, to make it more secure, or to create a copy for storage.
