FileFlows Flux

FileFlows Flux is a lightweight desktop companion application for FileFlows. It lets you process individual files or batches of files on demand, without having to set up a monitored library. You can process them locally on your machine, or hand them off to a FileFlows Server for processing; the finished file is then automatically downloaded back to your machine.

Why use Flux?​

Flux is for when you just want to convert a handful of files right now. You pick the files, choose the settings, and queue them. No monitored folders, no libraries, no setup.

Flux exists for those scenarios:

  • Ad-hoc conversions — Select files, choose output settings, and queue them for processing. No library setup required.
  • Local processing — Use the built-in conversion formulas directly on your desktop, without network round-trips.
  • Remote offloading — Send files to an existing FileFlows Server to be processed with a formula; the finished file is then automatically downloaded back to your machine.
  • Drag-and-drop simplicity — Drop files onto the app and pick your conversion settings in a dialog.

Two processing modes​

Every file you add to Flux can be processed in one of two ways:

ModeHow it works
LocalFlux processes the file directly on your machine using built-in processing pipelines. Free to use.
FileFlowsFlux uploads the file to your FileFlows Server, the server processes it using its configured formulas, and Flux downloads the result. Requires a licensed FileFlows Server with Flux enabled.

You can switch between modes in the conversion dialog for each file or batch.

Supported media types​

Flux ships with built-in conversion formulas for the most common media types:

  • Video — Transcode, resize, crop black bars, manage audio and subtitle tracks, and generate animated GIFs.
  • Audio — Convert between MP3, AAC, FLAC, and Opus; adjust bitrate, sample rate, and channel layout; apply loudness normalization; rename files using metadata patterns.
  • Images — Convert between JPEG, PNG, WebP, ICO, and ICNS; resize with multiple fit modes; adjust quality.
