My Podcast — Episode 12
0:42 / 2:00
How it works
Add your audio
Drag in any file — MP3, WAV, FLAC, M4A. Upload multiple clips, trim each one, set fades and volume, then reorder and merge.
Style the video
Choose a scene, add artwork, captions, text, and shapes, then make selected layers react to levels, frequency bands, or transients.
Export
MP4 at 720p, 1080p, or 4K · PNG thumbnail · GIF · Batch export all aspect ratios at once.

Portable Projects
Save a .wavsnap archive containing your project settings and media, then reopen it later or move it to another device.
Privacy & trust
Local editing and export
Normal editing and export run locally in your browser. WavSnap does not upload files to its own processing server.
Free, no account
No signup, no login, and no watermark. Open the editor and start creating immediately.
Privacy-first analytics
Hosted WavSnap counts anonymous page views without tracking cookies. Your media, project content, edits, exports, and diagnostic reports stay on your device unless you explicitly use a cloud feature or share a report.
Cloud features are optional
On-device Whisper needs a first-time model download. Gemini sends audio or caption text to Google only when you explicitly choose it.
