Are my files private on PDFScanner?

PDFScanner.io is a collection of 18 professional-grade PDF tools that run entirely inside your web browser. Unlike most PDF websites that upload documents to remote servers, PDFScanner processes everything locally on your device. Your confidential contracts, medical records, and financial statements never leave your device.

What Can You Do With PDFScanner?

PDFScanner covers the full spectrum of everyday PDF tasks without software installation or account creation:

Organize PDFs: Merge multiple documents, split large PDFs, compress oversized files, rotate misaligned pages, reorder pages visually, or extract specific pages.
Convert PDFs: Turn PDF pages into high-quality JPG images, combine multiple images into a single PDF, or convert HTML and web pages directly to PDF using your browser's print engine.
Edit & Secure PDFs: Annotate with text and shapes, apply text watermarks, add page numbers, embed handwritten signatures, password-protect files, remove restrictions from owner-locked PDFs, and extract text from scanned documents using OCR.

Why Browser-Based PDF Processing Is Superior

Server-based PDF tools require uploading your file — it travels over the internet, lands on a server, and sits in their storage until deleted, often hours later. PDFScanner uses a proprietary client-side processing engine that runs entirely within your browser. No file data crosses your network connection after the page loads.

FAQ

Frequently Asked Questions

Are my files actually private? Do they get uploaded anywhere?▼

Completely private. All processing happens directly in your browser. No file data is sent to any server at any point. You can verify this by opening your browser's Network tab during any operation — you will find zero file upload requests.

Is there a file size limit?▼

No enforced limit. The practical limit is your device's available RAM. Modern computers handle PDFs of several hundred MB comfortably. Very large files may process more slowly on older devices.

Do you add watermarks or branding to my processed PDF?▼

Never. Your output file is 100% clean. No logos, no watermarks, no added metadata identifying PDFScanner. Output is indistinguishable from a file processed by professional desktop software.

Can I use PDFScanner offline?▼

Yes. Once the page loads, all tools work without internet. The OCR tool downloads the Tesseract language model on first use, after which it also works offline.

What PDF tools are not available and why?▼

Word, Excel, and PowerPoint conversions are not currently available. These require Microsoft Office rendering engines to preserve formatting — there is no reliable free browser-based solution. We'll add these when a quality free option exists.
