Generation loss — quality may degrade
WMV uses lossy compression, and so does OGV. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your WMV file may contain ASF metadata, DRM tags metadata. OGV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
OGV lossy compression can produce blurring, blockiness (Theora). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
Para criadores de conteúdo, empresas e utilizadores do dia a dia, a conversão de formatos de vídeo é uma tarefa comum.

Em Portugal e no Brasil, a adoção do OGV é particularmente útil para garantir a acessibilidade em browsers mais antigos ou em sistemas operacionais menos comuns, onde codecs proprietários como o WMV podem não ter suporte nativo. Isso é crucial para inclusão digital, especialmente em regiões com infraestruturas tecnológicas diversas.

What Happens When You Convert WMV to OGV
Your WMV video is transcoded — video and audio streams are decoded and re-encoded into the OGV container. This is a lossy process that takes time proportional to the video duration.
Your WMV file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with OGV-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the OGV container and the file is saved

Frequently Asked Questions
Why won't my WMV file open?
WMV files may not open if your device lacks the right codec or application. Converting to OGV — a more widely supported format — usually resolves this. OGV (Ogg Video) is an open-source format using the Theora video codec.

How large can my WMV file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
Can I convert WMV to OGV on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
