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 OGV file?

OGV is an open, royalty-free video container format developed by the Xiph.Org Foundation as part of the Ogg project. It typically wraps Theora-encoded video alongside Vorbis or Opus audio streams, and is built entirely on patent-free, open-source codecs. Because it carries no licensing fees, OGV became the preferred video format for Wikipedia, Wikimedia Commons, and other platforms committed to free and open media.

How to open an OGV file

OGV files play natively in Firefox and other browsers built on open web standards, and open directly in VLC Media Player and MPV on Windows, macOS, and Linux. Native support is limited on Windows and macOS without an additional codec pack, so VLC is the most reliable cross-platform option.

What is a WebM file?

WebM is an open, royalty-free audiovisual media file format sponsored by Google, derived from the Matroska (MKV) container. Designed specifically for the HTML5 video element, it restricts streams to specific codecs: video is compressed using VP8, VP9, or AV1, while audio utilizes Vorbis or Opus. The format structure is defined by a subset of the Matroska specifications, prioritizing efficiency for web streaming and low computational overhead for decoding in browser environments.

How to open a WebM file

As a native HTML5 format, WebM files open directly in modern web browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, and Opera without plugins. For offline playback, cross-platform media players like VLC media player, MPV, and FFmpeg-based tools provide full support. Windows Media Player may require the installation of WebM Media Foundation Components to render these files.
