Video editing without
the upload.
Laysa Pro is a complete editor for cut, color and sound. It runs entirely in your browser, so your footage never has to leave your device. Nothing to install, no account to create.
Free to use. Works in Safari, Chrome and Firefox.
Interactive preview. Same editor as on /editor — play, trim and try the tools with the example clip.
Open full editorCut, grade, mix and deliver.
A focused set of tools that work together, so you can move from first cut to final export without switching contexts.
- Timeline
- Trim frame-accurate on a magnetic timeline. Ripple, roll and slip while everything stays in sync.
- Color
- Adjust exposure, contrast and saturation with precise, predictable controls. Refine subtly or build a look.
- Keying
- Pull a clean key and keep fine edges. Isolate subjects and composite directly on the timeline.
- Captions
- Add titles and subtitles with full typographic control. Import SRT or VTT, or create text timed to the frame.
- Audio
- Reduce noise and level dialogue where you edit. Shape the mix without leaving the project.
- Delivery
- Export H.264, HEVC, AV1 or ProRes locally, at full quality. The render uses your device, not a server.
All the formats you already use.
Import what you have. Export for where it is going. The render happens locally in your browser.
Built on FFmpeg compiled to WebAssembly. If a codec cannot be previewed natively, Laysa Pro generates a lightweight proxy. Your export still uses the original file.
Your footage stays with you.
Everything runs locally. Decoding, editing and rendering happen without uploads, servers in the middle or copies kept elsewhere.
No tracking for advertising. No training on your footage. Close the tab and the session ends on your device.
Open and start.
Laysa Pro opens in your browser. Your project is ready when you are.
Free to use. No watermark. Works offline after first load.
