Security Architecture & Privacy Model

How our client-side conversion engine keeps your sensitive documents completely private.

1. Local Browser Sandboxing

When converting confidential paperwork such as tax documents, identification cards, bank statements, or medical invoices, transmitting unencrypted files to unknown servers creates significant privacy vulnerabilities.

JPG to PDF eliminates this risk by performing 100% of the image reading, page rendering, and PDF compilation locally inside your web browser’s secure sandbox.

2. Zero Server Storage & Zero File Transmission

Here is how your file moves during the conversion process:

  1. Selection: You select JPG/JPEG files from your local storage.
  2. Local Reading: The browser's native FileReader API loads the image binary directly into local memory.
  3. Canvas Processing: Dimensions, aspect ratios, and user-selected rotations are computed on an offscreen HTML5 <canvas> element.
  4. PDF Compilation: The client-side jsPDF library arranges the image streams into a valid PDF binary structure in memory.
  5. Local Download: A temporary standard Blob URL (blob:https://...) is generated for you to download the file directly to your disk.

At no point in this sequence is file data transmitted across the Internet to any backend server.

3. Memory Lifecycle & Cleanup

All generated Blob object URLs and canvas references are scoped to the active browser tab. When you click "Clear All", reset the tool, or close your browser tab, the browser automatically garbage-collects and destroys all associated image memory buffers.

4. Use of Mature Open-Source Libraries

Our utility relies on mature, audited open-source JavaScript libraries (specifically jsPDF) hosted locally on our domain. We avoid closed-source binary plugins or opaque third-party conversion services.

5. Transport Layer Security (HTTPS)

All site assets, scripts, and stylesheets are served strictly over encrypted HTTPS with modern TLS certificates, ensuring no intermediary can inject malicious scripts into your browsing session.
