No. Everything - reading the PDF or image, applying the scan effect, and building the output - runs entirely in your browser with local JavaScript. Your document is never uploaded, logged, or transmitted anywhere. That makes it safe for sensitive paperwork like contracts, IDs, or signed forms.

Drop your PDF (or a PNG/JPG) onto the tool. Page one previews instantly with a default scanner profile. Pick a preset - Office MFP, Phone Scan, Old Fax, or Aged Paper - then fine-tune the sliders for rotation, contrast, grain, paper texture, and color mode. When it looks right, click Apply to all pages and export a multi-page PDF or a ZIP of images.

A digitally generated PDF (printed to PDF, exported from an app, or e-signed) has crisp edges, pure white backgrounds, and perfectly straight text. Real scans have slight rotation, sensor grain, crushed whites and blacks, paper texture, and edge shadows. This tool adds those physical cues back so the document reads as a genuine scan instead of a digital file.

Office MFP (B&W) mimics a black-and-white office multifunction copier: bitonal output, high contrast, light grain. Phone Scan (color) looks like a phone scanning app - color, soft focus, a warm cast and a stronger vignette. Old Fax is harsh, grainy, high-contrast bitonal. Aged Paper adds a warm off-white paper texture and a soft grayscale tone for a vintage look.

Yes. Randomness (page rotation, grain, paper fibres) is driven by a seed. Keep the seed and you get an identical result every time; click Re-roll to get a fresh random variation. Each page gets its own independent variance from the same seed, just like a real scanner where every page lands slightly differently.

Yes. Every page is rendered and processed independently, and each keeps its own dimensions and orientation, so a document with mixed A4/Letter or portrait/landscape pages exports correctly. Very large documents are capped with a warning to avoid running your browser out of memory - the cap is lower on mobile.

If a PDF is encrypted, the tool detects it and asks for the password so it can be opened locally in your browser. The password is only used in-memory to decrypt the file on your device - it is never sent anywhere. Without the correct password the file cannot be read.

Choose PDF for a single multi-page document (best for re-uploading where a "scanned PDF" is required). Choose PNG for lossless individual images, JPG for smaller individual images, or ZIP to download every page as a separate image in one archive. Higher DPI means sharper output but larger files and more memory use.
