Files never leave your device

How does it work?

PrivaPDF uses the open-source pdf-lib JavaScript library to perform all PDF operations entirely in your browser. Your files are never uploaded to any server — everything happens locally on your device using your browser's processing power. Merge multiple PDFs into a single document, split pages into separate files, compress to reduce file size, or add AES-256 password protection — all without any cloud infrastructure. Processing uses JavaScript running in your browser tab, with no server-side components whatsoever. When you close the browser tab, all document data is automatically cleared from memory. Your PDFs remain completely private from start to finish.

What is PrivaPDF?

PrivaPDF is a free, browser-based PDF toolkit that lets you merge multiple PDFs into one, split documents by page range, compress file sizes, and encrypt with AES-256 password protection — without uploading files to any server. Your documents are processed entirely in your browser using the open-source pdf-lib library, ensuring complete privacy for sensitive files like contracts, medical records, and financial documents.

How to Use PrivaPDF (3 Steps)

  1. 1

    Upload PDF Files

    Drag and drop or click to select your PDF files. For merging, add multiple files and drag to rearrange their order before combining. All files load directly into your browser's memory — nothing is uploaded.

  2. 2

    Choose Operation

    Select from four operations: Merge (combine multiple PDFs into one), Split (extract individual pages or custom page ranges), Compress (reduce file size with three quality levels), or Encrypt (add AES-256 password protection).

  3. 3

    Process & Download

    Click to process and download the result instantly — no waiting for server processing. Large merges, encryptions, and splits all complete in seconds directly in your browser.

Why Browser-Based PDF Processing Is Safer

Popular online PDF tools — Smallpdf, ILovePDF, Adobe online — upload your files to remote cloud servers for processing. For confidential documents like legal contracts, financial statements, or medical records, this creates a serious privacy risk. PrivaPDF uses the open-source pdf-lib JavaScript library to handle all PDF operations in your browser's memory. Your PDFs never leave your device at any point.
