Privacy-First Offline Video Editor
Edit and convert videos right in your browser. No uploads, no accounts, no watermarks.
Why privacy-first?
Klippy runs on-device using WebAssembly, WebGPU, and WebCodecs. Your media stays local and exports never leave your machine unless you decide to share them. Install as a PWA to work fully offline.
Local AI: Text-to-Speech
Generate natural narration in the browser with Kokoro TTS—no server calls after assets are cached.
On-Device Export
Render MP4/WebM/GIF using FFmpeg/WebCodecs entirely in your browser. Up to 4K depending on hardware.
Video Conversion
Trim, rotate, crop, watermark, and convert formats without uploading files anywhere.
Captions & Subtitles
Import SRT or generate word-timed text and style it with presets for readability.
How it works
- Create a project and choose your canvas size.
- Drag and drop videos, images, and audio — everything stays local.
- Edit on the timeline with text, overlays, and effects.
- Export to MP4/WebM/GIF directly in your browser.
FAQs
Does Klippy upload my files?
No. Core editing and export are local. Optional stock search or AI calls use your keys and can be disabled.
Can I work offline?
Yes. Install as a PWA so the app, WASM, and models are cached. Then you can edit, TTS, and export offline.
Which browsers are supported?
Latest Chrome, Edge, and Chromium-based browsers work best. Safari support varies for WASM threads.
