About Scanner Effect
Make Your PDF Look Like a Physical Scan
Scanner Effect applies visual transformations that make a digital PDF look like it was printed and then scanned. The tool adds contrast boost, grain noise, sepia aging, and brightness adjustments in a calibrated combination.
OxygenPDF offers three built-in presets — Clean Scan, Old Document, and Photocopy — plus manual sliders for each parameter. A live preview shows the effect on your actual pages. Everything runs in your browser.
Why People Simulate a Scan
It sounds strange, but there are legitimate reasons to make a digital document look scanned.
Document Uniformity
When mixing scanned and digital pages in one file, applying a scanner effect to the digital pages makes the whole document look consistent.
Vintage Aesthetic
The Old Document preset adds sepia tone and aging noise. Useful for design projects, props, or presentation materials that call for an aged-paper look.
Quick Scanned Copies
Sometimes you need a document to look like a photocopy for administrative or archival purposes. The Photocopy preset produces a high-contrast, noisy result.
Testing & Prototyping
Developers building OCR or document-processing pipelines use scanner effects to generate realistic test data from clean PDFs.
Three Presets, Four Sliders
Clean Scan adds a slight contrast boost with minimal noise — it looks like a well-maintained office scanner. Old Document applies warm sepia tone with visible grain, mimicking a document that’s been photocopied several times over the years. Photocopy cranks up contrast and noise with a darker output, simulating a low-quality office copier.
Each preset is a starting point. Four manual sliders let you dial in the exact look: contrast (0–100), noise (0–50), sepia amount (0–1), and brightness offset (-50 to +50). Adjusting any slider switches to custom mode. The live preview updates as you tweak.
How It Compares
Scanner effect is a niche tool. Very few PDF utilities offer it at all.

The scanner effect is applied entirely in your browser. Pages are rendered to canvas, processed, and rebuilt into a new PDF on your machine. Nothing gets uploaded.
