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
Render to MP4 (H.264) or WebM with hardware-fast WebCodecs encoding, straight to a file on your disk.
Autosave and projects
Your session autosaves in the browser, and projects can save themselves to a file on your computer so nothing is ever lost.
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. It is read locally by your browser; nothing is uploaded to any server.
Edit on the timeline
Cut, trim, rearrange, add overlays, captions, effects, music and voiceover. Everything previews live as you work.
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
Most online editors upload your video to their servers before you can touch it. Trimzio never does. Your file is opened directly by your browser, edited on your machine, and exported to your disk. Close the tab and nothing of yours is left behind anywhere.
- No uploads, ever: the video never touches a server
- No account, no email, no tracking of your content
- Ideal for private, sensitive or client footage
