| Platform | Minimum version | Architecture | Download |
|---|---|---|---|
| macOS | 11 (Big Sur) or later | Apple Silicon + Intel (Universal Binary) | ~79 MB |

Linux and mobile: coming soon.
fwip is a lightweight desktop app. If your computer runs a modern browser, it can run fwip.
macOS
Minimum: macOS 11 Big Sur (2020) Supported: macOS 11 and later Architecture: Universal Binary. Runs natively on both Apple Silicon (M1, M2, M3, M4) and Intel Macs. No Rosetta translation needed on Apple Silicon. Download size: ~79 MB
How to check your macOS version: Apple menu → About This Mac → look for the version number.
Installation: Download the .dmg file, drag fwip to your Applications folder, and open it. The app is code-signed with our Apple Developer ID and notarised by Apple, so it opens without warnings on supported macOS versions.
Windows
Minimum: Windows 10 or Windows 11 Supported: Windows 10, Windows 11 Architecture: 64-bit (x64) Download size: ~40 MB
Not supported: Windows 7, Windows 8, Windows 8.1, 32-bit systems, ARM-based Windows devices.
How to check your Windows version: Settings → System → About → look for “Edition” and “Version.”
WebView2 runtime: fwip uses Microsoft’s WebView2 for rendering. It’s pre-installed on Windows 11 and most recent Windows 10 installations. If fwip shows an error on first launch about a missing runtime, download WebView2 from Microsoft’s website. It’s free and takes 30 seconds to install.
Installation: Download the .msi installer, run it, and follow the prompts. The app is code-signed by FWIPIT PTY LTD via SSL.com (OV certificate). As a new publisher, Windows SmartScreen may show a prompt until download reputation builds. Click “More info” then “Run anyway.” Notarisation is a macOS-only concept, so the Windows build is signed but not notarised.
Linux and mobile
Coming soon. We are not yet shipping a Linux build or a native mobile app. For now, fwip’s web tools work in any modern Linux or mobile browser at fwip.app.
Hardware
fwip is lightweight. There are no heavy hardware requirements.
- RAM: 4 GB minimum (8 GB recommended for working with large files)
- Disk space: ~40 MB on Windows, ~80 MB on macOS
- Processor: Any 64-bit processor from the last 8 years
- GPU: Not required. All processing is CPU-based.
- Internet: Not required after installation. fwip works completely offline. An internet connection is only needed to download the app and validate your licence key once.
Large files
The desktop app removes the file size limits from the web version. There’s no hard cap on file size in the desktop app; it’s limited only by your available RAM. As a practical guide:
- 100 MB files: No issues on any supported system
- 500 MB files: Works well with 8 GB+ RAM
- 1 GB+ files: Works but may be slow on systems with less than 16 GB RAM
Tools that accept multiple files (such as image conversion, resize and compress) process them one at a time to keep memory usage reasonable. Large selections work but take longer.
Troubleshooting
macOS: “fwip can’t be opened because it is from an unidentified developer” This shouldn’t happen. fwip is signed and notarised by Apple. If you see it anyway, right-click the app, choose Open, then click Open in the dialog. This only happens once.
Windows: SmartScreen warning New code signing certificates take time to build reputation with Microsoft. If SmartScreen flags fwip, click “More info” then “Run anyway.” The app is signed by FWIPIT PTY LTD via SSL.com. You can verify the publisher in the dialog before running.
Any platform: WASM engine fails to load Make sure you’re running a supported OS version. Older operating systems may have outdated WebView components that don’t support the WebAssembly features fwip needs.
