About ScanPDFOnline

ScanPDFOnline is a free, browser-based document scanner. Point your phone or webcam at a piece of paper, and we turn it into a scanner-quality PDF in seconds — no signup, no installation, no upload.

Our promise

• Nothing leaves your device. Camera capture, image filtering, PDF creation, OCR — all run inside your browser using standard web APIs. We do not run a server that receives your files.
• Free forever. The core scanner and PDF tools have no watermark, no page limits, no forced sign-up. The site is supported by unobtrusive display ads.
• Works everywhere. Any modern browser on any device: iPhone, Android, Chromebook, Windows, Mac, Linux.

How it works

ScanPDFOnline is a static site — every page is prerendered as plain HTML and served from Cloudflare's global network. When you use the scanner, your browser opens the camera via the standardgetUserMedia API, captures a JPEG, runs a small image-processing pipeline (contrast, brightness, saturation), and uses the open-source jsPDF library to bundle pages into a PDF. For OCR we use Tesseract.js, a WebAssembly build of Google's Tesseract OCR engine.

Who we are

ScanPDFOnline is built and maintained by a small independent team. We've run similar tools in other verticals (calorie references, time calculators) and applied the same principles here: fast, honest, no dark patterns.
