Scanner Effect
Transform a clean digital PDF into something that looks like it came out of a flatbed scanner. The tool applies configurable noise, slight rotation, blur, brightness shifts, and optional yellowing to simulate the imperfections of a physical scan.
How It Works
- Upload your PDF file.
- The editor opens with a live preview of the first page alongside a settings panel.
- Adjust the scan effect parameters using the sliders and toggles.
- The preview updates in real time as you change settings.
- Click Apply to process all pages and download the result.
Options
- Colorspace (Grayscale toggle) -- Convert the output to grayscale for a classic black-and-white scan look.
- Border -- Add a subtle dark border around the page edges to mimic scanner border artifacts.
- Rotate -- Apply a slight rotation (-5 to +5 degrees) to simulate misaligned paper feeding.
- Rotate Variance -- Add random variation to the rotation angle so each page tilts slightly differently.
- Brightness -- Shift the overall brightness up or down.
- Contrast -- Adjust contrast to simulate toner quality variations.
- Blur -- Apply Gaussian blur to soften text edges like a low-quality scan.
- Noise -- Add random pixel noise to simulate scanner sensor grain. Higher values produce grainier results.
- Yellowish -- Add a warm yellow tint to simulate aged or recycled paper.
- Resolution -- Set the output DPI. Lower values create a more pixelated, scan-like appearance.
- Reset -- Restore all settings to their defaults.
Features
- Real-time preview that updates as you tweak each parameter
- Per-page random rotation variance for realistic variation
- Ten independently adjustable parameters
- Grayscale mode for authentic black-and-white scan output
- Resolution control from low-DPI fax quality to high-DPI archive quality
Use Cases
- Making digitally created documents appear to have been scanned and printed
- Simulating physical document aging for historical document recreation
- Testing OCR software against degraded scan quality
- Producing documents that match the visual style of existing scanned archives
Tips
- Start with subtle values. A noise level of 10-20, a slight 0.5-degree rotation, and minimal blur already produce a convincing scan look.
- Combine grayscale mode with slight yellowing for a "photocopy of a photocopy" effect.
- Lower resolution settings (100-150 DPI) create the most realistic fax-machine appearance.
