The codec to encode the video track. Codec "Without reencoding" copies the video stream from the input file into output without re-encoding if possible.
Set the video quality in a VBR mode. Choose "Custom" if you need to set a fixed bitrate (CBR).
Set an output video resolution by selecting one from the predefined set of the most popular resolutions or manually entering a custom resolution.

ogv

OGV (Ogg Video) is an open multimedia format that combines the Theora video codec with the Ogg container, both developed by the Xiph.Org Foundation as royalty-free alternatives to proprietary media formats. Theora 1.0 reached stable release in November 2008, though development had been underway since 2002 based on the VP3 codec donated by On2 Technologies. Theora compresses video using block-based motion compensation with discrete cosine transform coding, achieving quality roughly comparable to MPEG-4 Part 2 at similar bit rates. The Ogg container uses a page-based multiplexing scheme that interleaves Theora video with Vorbis or Opus audio, supporting features like chained streams for seamless concatenation and multiplexed streams for synchronized multimedia playback. OGV was historically significant in the push for open web standards, serving as one of the first freely implementable video formats proposed for the HTML5 video element. Firefox and Chrome both shipped native OGV support, demonstrating that web video could function without reliance on proprietary plugins or licensed codecs. The format also supports FLAC lossless audio, Kate subtitle streams, and Skeleton metadata within the Ogg container. While WebM and AV1 have largely replaced OGV in the open-source video landscape, the format remains available in Linux distributions, open-source media tools, and contexts where complete freedom from patent concerns is a priority.

asf

ASF (Advanced Systems Format) is a proprietary digital media container developed by Microsoft to support streaming over networks. Introduced in 1996, it was originally called Active Streaming Format and later renamed to Advanced Streaming Format before receiving its current name. ASF serves as the underlying container for Windows Media Audio (WMA) and Windows Media Video (WMV) content, though it can accommodate data from any codec. The format was architected with network delivery in mind, incorporating features such as forward error correction, scalable bit rate support, and the ability to seek within streams without downloading the entire file. ASF files include a header object containing metadata, a data object holding the actual media content, and optional index objects that enable efficient random access. One key advantage is built-in support for digital rights management, which made ASF a popular choice for commercial content distribution during the early days of online media. The container handles multiple synchronized streams, including video, audio, script commands, and metadata markers. While ASF has been largely superseded by more modern containers in many use cases, it remains relevant in legacy Windows media ecosystems and enterprise environments that rely on Windows Media Services infrastructure.

Server-Side Work

All encoding runs on our cloud servers. Convert OGV to ASF without taxing your own hardware.

Privacy Protected

Uploaded OGV files are deleted right after processing. ASF results are purged within 24 hours.

How to convert OGV to ASF

1

Select or drag&drop OGV video to convert it to the ASF format from your computer, iPhone or Android. Moreover, it is possible to choose it from your Google Drive or Dropbox account.

2

Now your video is uploaded and you can start the OGV to ASF conversion. If it is needed, change the output format to one of the 37 video formats supported. After that, you can add more videos for batch conversion.

3

If you want, you can customize such settings as resolution, quality, aspect ratio and others by clicking the gear icon. Apply them to all the video files if necessary and click the button "Convert" to process.

4

Once your video is converted and edited, you can download it to your Mac, PC or another device. If necessary, save the file to your Dropbox or Google Drive account.

Frequently Asked Questions

Why convert OGV to ASF?

ASF is designed for Windows Media streaming systems. Converting from OGV gives your content access to platforms that do not support Theora.

What plays ASF files?

VLC and format-specific players handle ASF. Check compatibility with your intended playback device or platform.

Will the audio be preserved?

Yes — both video and audio from your OGV file are re-encoded and included in the ASF output.

Can I process multiple files?

Upload several OGV videos and convert each to ASF simultaneously in one batch operation.

Is my data safe?

OGV uploads are erased immediately after conversion. ASF output files are deleted within 24 hours.
