Rassio Forge User Guide
Everything you need to install, configure, and get the most out of Rassio Forge.
Getting Started
System requirements: Windows 10 or 11 (64-bit), 4 GB RAM minimum, 200 MB disk space.
Download the Rassio Forge installer from your account dashboard and double-click it. It takes about a minute; the app then opens from the Start menu.
Quick Start
1. Drop image files or a folder onto the left panel. 2. Check the sizes you want in the preset list. 3. Choose an output folder. 4. Click START PROCESSING.
Presets
Presets define the output dimensions. 57 presets are included (cm, inch, ISO A-series). Add custom presets in cm, inches or pixels via the + button in Settings.
Processing Modes
Crop + Resize — crops the image to the exact ratio, then resizes to the target DPI. Best for wall art.
Stretch — stretches the image to fill the exact dimensions. May distort non-square images.
Resize Only — resizes to fit within the target size while preserving aspect ratio.
Edge Options
Edge options add canvas wrap to the sides of the image for gallery-wrapped prints. Gallery Wrap, Mirror Wrap, Colored, and Blurred are available.
Output Formats
TIFF (LZW/ZIP), PNG, JPEG (quality adjustable 80–100), PDF (lossless). Select multiple formats for the same batch.
Naming Patterns
Default pattern: {name}_{w}x{h}{unit}_{mode}{rtp}.{ext}. Add prefix/suffix in the settings panel. Live preview available before processing.
License & Activation

FAQ & Troubleshooting
If the app won't start, ensure you're on Windows 10/11 64-bit. For processing errors, check that input images are not corrupted. Contact support for anything else.
