Everything you need to get started, configure your workflow, and troubleshoot issues.
Download Duplyfi for Windows, macOS, or Linux from the download page. Run the installer and follow the on-screen instructions. The application auto-updates when new versions are available.
Visit duplyfi.com and create an account with your email. You get a 24-hour free trial with full access to all features. No credit card required.
Open the Duplyfi desktop app and sign in with your account credentials. Your license is automatically activated and your device is bound to your account. Each account supports up to 2 devices.
The Video Repurposer takes a single source video and generates multiple unique variations by applying a combination of effects. Each output is pixel-fresh and metadata-clean, designed to bypass duplicate detection on platforms like TikTok, Reels, Shorts, and Pinterest.
Drag and drop video files into the application, or use Ctrl+O to open a file picker. Use Ctrl+Shift+O to open a folder and batch-import all video files within it.
Duplyfi includes 35 effects across five categories: Color (saturation, contrast, brightness, vignette, gamma), Motion and Geometry (speed, zoom, rotation, flip, dimensions, random pixel size), Effects (noise, pixel shift, waveform shift, blurred border, cut video), Audio (volume, audio bitrate), and Encoding (framerate, video bitrate, US metadata).
Configure your desired effects and their ranges, set the number of outputs, then press Ctrl+Enter or click the Start button to begin processing. Output files are saved with randomized filenames to prevent tracing back to the original.
The Image Spoofer applies subtle, undetectable modifications to images including metadata stripping, pixel-level noise injection, and dimensional adjustments. Each output is unique at the binary level while remaining visually identical to the original.
JPEG, PNG, WebP, and TIFF are supported as input. Output format matches the input by default, or can be configured in settings.
Duplyfi ships with 5 built-in presets optimized for common use cases: Gentle (minimal, undetectable changes), Moderate (balanced changes), Aggressive (maximum variation), Audio Focus (audio-only modifications), and Speed Ramp (timing variations).
Create your own presets by configuring effects to your preferred values, then saving them via the Preset Maker. Custom presets can be edited, duplicated, and deleted.
Presets can be exported as JSON files and imported on other devices or shared with team members. Use the export button in the Preset Maker to save presets externally.

Duplyfi bundles FFmpeg automatically. If you see this error, try reinstalling the application. On Linux, ensure the AppImage has execute permissions (chmod +x).
Ensure you have an active internet connection. If the error persists, check that your subscription is active in the Lemon Squeezy portal. If you have reached your device limit, deactivate another device first.
Video processing is CPU-intensive. Close other heavy applications during batch processing. Reducing the number of concurrent worker threads in Settings can help on lower-end hardware.
Ensure your effect ranges are not set to zero. At least one effect must have a non-zero range for outputs to vary from each other.
Delete the application config folder and restart. On Windows: %APPDATA%/duplyfi, on macOS: ~/Library/Application Support/duplyfi, on Linux: ~/.config/duplyfi. If the issue persists, contact support@duplyfi.com with your OS version.
