Local-first video editing
Edit video right in your browser. Your footage stays on your computer.
Trimzio opens your footage from disk, edits it locally, and exports without a watermark. Core editing needs no account. Local-only mode is on by default and blocks optional cloud AI and transcription.

Everything you need
A real editor, not a toy
Trimzio covers the whole everyday editing workflow, from first cut to final export.
Cut, trim and rearrange
Split at the playhead, trim clip edges, drag clips around a multi-track timeline. Combine several videos into one edit.
Text and image overlays
Drop text, logos, stickers or picture-in-picture video onto the preview and drag them exactly where you want them.
Captions and subtitles
Write captions by hand or import .srt / .vtt files. Style them, animate them, and bake them into the export.
Color and effects
Brightness, contrast, saturation, vignette, film grain, fades, crop, rotate, and Ken Burns motion, all live on the preview.
Music and voiceover
Add music beds and sound effects on their own lanes, or record a voiceover with your mic while the video plays.
Noise cancellation
Clean up background hum, hiss and rumble per clip, with profiles tuned to keep speech clear.
Fast export
Run export preflight, then render locally to MP4 or WebM with fast WebCodecs encoding when supported and a compatible fallback.
Review workspaces
Add timestamped notes and approval checks locally, or sign in to sync feedback with invited workspace members. Footage is never uploaded.
Free smart tools
Remove silences, find shots, mark beats, balance levels, run adaptive recipes, and reuse workflows locally without an account.
Optional AI assistant
Sign in to describe edits in plain language or transcribe speech when you choose. Local-only mode blocks these cloud requests by default.
Installable offline app
Install Trimzio from a supported browser and keep core editing available offline after the first successful load. A system check explains browser capabilities.
How it works
From file to finished video in three steps
Open a video
Drop a file into the editor or pick one from your disk. Core editing reads it locally instead of uploading the source video.
Edit on the timeline
Cut, trim, rearrange, add overlays, captions, effects, music and voiceover, or use the free offline smart tools. Optional online AI is available when you want it.
Export to your disk
Render to MP4 or WebM at the quality you choose. The finished file saves straight back to your computer.
Privacy by design
Your footage stays yours
Core editing opens media from disk, processes it on your machine, and exports locally. Optional AI is separate: prompts and project context go online, and transcription sends audio only after approval. Local-only mode blocks both services.
- Core editing and export stay on your device
- No account is required for core tools or offline smart tools
- Local-only mode blocks online AI and transcription
