Get Spark Tray for Windows
A small, quick installer. The app and all five utilities run entirely on your machine — free, no account, no sign-in.
System requirements
Spark Tray is a native Windows app. Here's what it needs, and how downloads work.
Operating system
Windows 10/11 (x64)
Architecture
64-bit (x64) processor
Installer size
~100–150 MB, models download on demand
AI models
Downloaded on demand, only when a feature needs them
What's in the download
The installer is deliberately lean. The big AI models arrive later, only if and when you actually need them.
In the installer
- The Spark Tray app and all five utilities
- Video downloader, audio extractor, and the bulk queue manager
- Background remover and transcriber interfaces
- Everything needed to run locally — no account, no sign-in
What downloads later (models)
- The background-removal model (first time you remove a background)
- The speech-to-text model (first time you transcribe)
- Fetched once, then cached on your machine for reuse
- Skip anything you don't use — nothing heavy ships up front
Signed & verifiable
EV Authenticode code-signed
Every Spark Tray installer is signed with an Extended Validation Authenticode certificate. Windows SmartScreen and the User Account Control prompt will show Spark Tray as the verified publisher, so you can be sure the file came from us and hasn’t been tampered with in transit.
A published SHA-256 checksum will appear here alongside the first public release, so you can verify your download independently of the signature.
If Windows shows a SmartScreen warning
Our installer is signed with a brand-new certificate that hasn’t built up reputation yet, so the first people to download may see a blue “Windows protected your PC” screen. It’s expected and harmless. Click More info → Run anyway to continue. The warning clears itself as more people install safely.
Honest about how this is funded
Spark Tray is free to download and runs locally. We’re open about how the project stays funded — no hidden strings, no selling your data, no surprise upsells buried in the installer.
