Cut clips, combine footage, convert formats, extract audio, and prepare content for publishing.
The Problem
Cloud transcoders are
expensive & slow, exposing your private video folders
to external servers.
The Problem
Large video files take
forever to upload, occupy disk
space, and trigger high bandwidth bills.
The Problem
Online tools come with
file size limits, watermarks,
and privacy risks.
Optimize images, change dimensions, convert formats, and create PDFs from media assets.
Cut footage precisely while maintaining original quality.
Convert Video Audio Into MP3 Format For Playback, Sharing, Or Archiving.
Export High Quality WAV Audio For Editing, Production, And Professional Use.
Extract audio from videos and export in multiple formats including MP3, WAV, AAC, and FLAC.
No accounts, subscriptions, cloud uploads, or unnecessary distractions.
A look inside
Captured from the 0.1.2 builds: the Windows app running on Windows 11, and the Mac app on Apple Silicon.
Progress shows in each row while files are processed one after another. Finished rows show the new size and link to the result.
The action picker searches all 66 tools and suggests the ones that fit your files. Ctrl+K on Windows, Cmd+K on macOS.
A thumbnail strip with a two-handle range slider, synced with the Start and End boxes. Fast cuts without re-encoding, or precise re-encoded ones.
Save the sound track of a video as MP3 (or another audio format), next to the original or in a folder you choose.
Change the format, set the quality and size, and strip EXIF and GPS data. Every row shows how much space you saved.
Add the files, reorder them with the arrows and merge. Split, rotate, compress, protect and unlock are in the same list.
Word, ODT and other documents to PDF, and back. LibreOffice is bundled with the Windows installer and with the Mac app.
Reopen or reveal anything you converted from the Results panel (the newest 200 are kept), and save a tool’s options as a preset.
One button cycles system, light and dark.
Give the file list or the options more room. Panel width and window size are remembered.
Below a certain width the options move under the file list, so the window stays usable on small screens.
The same app on Apple Silicon, with the action picker on Cmd+K.
Two videos converted to GIF, with the output name and size on every row.
Everything in one window
Each tool runs a bundled, well-known program on your own machine and shows only the options it needs, in plain language. The earlier app had 33 tools; 0.1.2 has 66. Click a tool to open its step-by-step guide.

KinoFlux Editor is a batch toolbox, not a multi-track timeline editor: one action at a time on a list of files. Presets save your favourite options per tool, and a results panel keeps your last 200 jobs.
How-to guides
Short guides for everyday jobs, with real screenshots of the app, the options that matter and what each tool cannot do.
Offline & private
No network code. The program never opens a connection: no accounts, no telemetry, no analytics, no crash upload and no update check.
Your files stay put. Everything is converted on your computer by bundled programs. Nothing is uploaded, and originals are never changed.
Nothing sensitive stored. Only settings, presets, history, logs and crash reports are written, in per-user folders. No file contents and no passwords.
The privacy policy is also built into the app (press F1).
To be precise: bundled FFmpeg, Poppler and LibreOffice contain network features of their own. KinoFlux Editor only hands them local files and starts LibreOffice headless, so those features are not reachable from the app. That is a design guarantee, not an operating-system sandbox; if you need a hard guarantee, block the program in your firewall.

Bundled programs (FFmpeg as a GPL v3 build, ImageMagick, qpdf, Poppler, LibreOffice) keep their own licences; full notices ship with every package and are shown in the app under About › Third-party.

Version history
First release of the native (Rust + GPUI) KinoFlux Editor.
Earlier releases (up to 0.1.1) are superseded and remain on the GitHub releases page.
FAQ
Yes. KinoFlux Editor is free to download and use: no subscription, no watermark on results and no account. It is proprietary software (not open source) © 2026 ntxm.org. The licence lets you install and run it on computers you control for personal or internal business use, including processing files for paying clients. Redistribution is limited to the official, unmodified installer or package.
No. Your files are converted on your computer by the bundled programs (FFmpeg, ImageMagick, qpdf, Poppler and LibreOffice). The app has no accounts, no telemetry, no analytics, no crash upload and no update check, and it never opens a network connection. You can disconnect from the internet and everything still works.
Never. Results are written as new files next to the originals (for example clip_converted.mp4 or report_merged.pdf), with “ (2)” added if the name already exists, or into a folder you choose under “Save to”.
No. KinoFlux Editor is a batch toolbox for everyday jobs: convert, compress, trim, join, change speed, rotate, make GIFs, burn in subtitles, extract or replace audio and more. It has one action at a time on a list of files, not a multi-track timeline.
0.1.2 is the first release of the native app, written in Rust with the GPUI toolkit (no Electron, no webview). It has 66 tools (53 at launch on 2026-10-03, 13 more in the update of 2026-10-05), a single-window design with a draggable splitter, and adds an installer on Windows and a macOS (Apple Silicon) version.
Windows 10 (1809) and Windows 11, 64-bit, and Macs with Apple Silicon (M1 or newer) running macOS 11 or later. Intel Macs and Linux are not offered at the moment.
Yes. It is listed as “Kinoflux Editor” (product ID 9NXKR2GV1WM7). The Store version is the same free app; the Store installs it and keeps it updated, and because Store apps are signed by Microsoft there is no SmartScreen warning. The installer from this page stays available for anyone who prefers it.
The installer and the program are not code-signed yet, so Microsoft SmartScreen may warn about an unknown publisher. Click “More info”, then “Run anyway”, or install the Microsoft Store version instead. You can compare the SHA-256 of your download with the value on this page (certutil -hashfile <file> SHA256) before you run it.
The Mac app is ad-hoc signed but not notarized by Apple, so Gatekeeper blocks the first start. Click “Done” (not “Move to Bin”), open System Settings › Privacy & Security, scroll to “KinoFlux Editor was blocked” and press “Open Anyway” (macOS 15 and newer). On macOS 14 and older, right-click the app › Open also works. You only need to do this once.
Yes. The Mac app includes LibreOffice 26.2.6 (the official build from The Document Foundation, unmodified), so the 14 Documents tools (Word, Excel, PowerPoint, OpenDocument, CSV and HTML to and from PDF, and documents to pictures) work out of the box and there is nothing else to install. That is why the disk image is about 344 MB and the app is about 1 GB once installed. If the Documents tools ever show a notice that LibreOffice was not found, download the disk image again and reinstall the app. On Windows LibreOffice is included in the installer too.
Settings, presets and the last 200 results live in your own user profile (Windows: %APPDATA%\KinoFlux Editor; macOS: ~/Library/Application Support/KinoFlux Editor), plus a small log folder. The Windows uninstaller asks whether to delete them too. On a Mac, drag the app to the Trash and delete those folders if you want them gone. Your converted files are never touched.
KinoFlux Editor itself is proprietary. It ships with independent programs under their own licences: FFmpeg (a GPL v3 build), ImageMagick, qpdf, Poppler, LibreOffice and many Rust libraries. Full licence texts, versions and source-code locations are included in every package and shown in the app under About › Third-party (press F1).
