How it works

Three steps to your converted file

Everything happens in your browser tab - upload, pick a format, download. The heavy lifting runs on our servers.

01

Upload your file

Drag and drop, click to browse, or paste a URL. Batches take up to 20 files at once - 230+ input formats across video, audio, image, document, and archive types.

02

Choose an output format

Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

03

Convert & download

Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.

What is an OPUS file?

Opus is a modern, royalty-free lossy audio codec standardized by the IETF (RFC 6716). It combines the SILK codec (originally built for Skype) with the CELT codec to deliver high audio quality at very low bitrates and latency, scaling smoothly from low-bitrate speech to high-fidelity music. Its efficiency and low latency have made it the default codec for WebRTC, Discord, WhatsApp, and Microsoft Teams voice and video calls.

How to open an OPUS file

Opus files play natively in VLC Media Player, Firefox, and Chrome, and most modern operating systems include native decoder support. On older systems or media players without Opus support, the format can be converted to a more universally compatible format like MP3 or WAV.

What is a WAV file?

The Waveform Audio File Format (WAV) is a raw audio bitstream standard developed by Microsoft and IBM, serving as a subset of the Resource Interchange File Format (RIFF) specification. It primarily stores uncompressed Linear Pulse Code Modulation (LPCM) audio data, making it the industry standard for archival and high-fidelity mastering on Windows systems. The format supports varying bit depths and sample rates, with the Red Book standard (44.1 kHz, 16-bit stereo) being the most prevalent implementation.

How to open a WAV file

WAV files enjoy near-universal native support across all major operating systems due to their status as a foundational audio standard. Windows Media Player, Apple QuickTime, and Linux-based media players (via ALSA/PulseAudio) open WAV files by default without requiring external codec packs or third-party software.
