About video file conversion

Video conversion re‑encodes your footage to a different container or codec (for example MOV to MP4 or MKV to WebM). This is useful for reducing size, improving playback compatibility, or preparing clips for the web and social media.

Popular video conversions

• MOV to MP4 – improve compatibility across devices.
• MKV to MP4 – convert for editing or sharing.
• MP4 to WebM – modern, open format for the web.
• AVI to MP4 – smaller files with broad support.
• WebM to MP4 – export for platforms that require MP4.
