Trizr
macOS video editor

Trim, join & blur video, right on your Mac.

Trizr is a fast, native editor for quick cuts. Drop in a clip, trim it, stitch pieces together, blur out anything private — then export up to 4K. No account. No cloud. Nothing leaves your machine.

01 — What it does

Everything you need for a quick cut. Nothing you don't.

A focused toolset that stays out of the way — built with SwiftUI to feel like it belongs on macOS.

Trim with precision

Drag the handles or split on the playhead. A 0.3 s minimum keeps cuts clean, and every edit is undoable.

Frame-accurate

Join & reorder

Drop several clips on the timeline, drag to reorder, and stitch them into one continuous export.

Multi-clip timeline

Blur what's private

Draw a box over a face, a name, or a screen. The blur mask rides along with the clip until you export.

Region masking

Filmstrip timeline

Real thumbnails and an audio waveform, with pinch-to-zoom from a bird's-eye view down to the frame.

Thumbnails + waveform

Export your way

MP4 (H.264) for sharing or MOV (ProRes) for quality, at 480p through 4K. Live size estimate before you commit.

Up to 3840×2160

Private & native

Sandboxed and fully offline — Trizr has no network access at all. It reads only the files you hand it.

No tracking, ever
02 — A closer look

Designed to feel effortless.
