How to convert video online for free
Choose a video file or paste a link
Drag a file into the upload area, or click "Choose Video". VideoClaude supports MP4, MOV, MKV, WebM, OGV, M4V, MPEG, and audio formats like MP3, FLAC, OGG. Or switch to the "Download from URL" tab to fetch a video from an external site.
Pick the output format and quality
Choose a video format (MP4, WebM, MOV, MKV, M4V, MPEG, OGV) or an audio-only format (MP3, AAC, WAV, FLAC, OGG). You can also adjust resolution and quality before converting, or choose download quality for an external link.
Convert or download, then save the file
Click Convert or Download and wait for processing to finish. Local file conversion runs entirely inside your browser and is never uploaded to any server. Once done, download the resulting file directly.
Why convert video formats?
Every device, editor, and platform expects a different video format. iPhones record in MOV, while most Android devices and web browsers prefer MP4. Professional editors favor MKV for encoding flexibility, while WebM works best with browsers. Converting formats lets you play video on any app or social platform without losing content. If your file is too large to share, you can compress video online using the dedicated compression tool. Compress Video Online.
Supported formats
VideoClaude supports all common video formats as input and output: MP4, WebM, MOV, MKV, M4V, MPEG, OGV. For audio-only conversion you can extract to MP3, AAC, WAV, FLAC, OGG. The converter runs entirely in your browser, so your files are never uploaded to a server. Need to cut a clip instead of converting the whole thing? Use the online video trimmer to cut MP4, MOV, WebM, MKV files directly in your browser — no upload, no sign-up. Want an animated image for chat or documentation instead of a video file? You can convert video to GIF the same private, browser-based way, with no watermark on the result. Trim Video Online — Video to GIF Converter.
