Pro tip for WebM files
WebM uses VP8/VP9 video codecs. CutSnap transcribes the audio and exports with burned-in captions as MP4 for broader platform compatibility.
How It Works
Add Subtitles to WebM in 3 Steps
1. Upload Your WebM
Drag and drop your .webm file into CutSnap. No conversion or pre-processing needed — CutSnap handles WebM files natively.
2. AI Transcribes Audio
CutSnap's AI transcription extracts the audio from your WebM file and generates accurate, word-level timestamped captions automatically — in over 50 languages.
3. Export with Captions Burned In
Style your subtitles in the live WYSIWYG editor, then export. Your captions are permanently burned into the video — guaranteed to display on every platform and device.
