Privacy Policy

Your privacy is our priority. 100% client-side processing.

Privacy First

Just Image Converter is designed with your privacy as the top priority. We follow a simple principle: what happens in your browser, stays in your browser.

No Data Collection

We do not collect, store, transmit, or process any of your files or personal data. Period.

  • No file uploads: All image processing happens locally in your web browser using JavaScript
  • No server storage: Your images never leave your device
  • No tracking: We don't use analytics, cookies, or tracking scripts
  • No accounts: No sign-ups, logins, or user databases
  • No third parties: No CDNs, external APIs, or third-party services

How It Works

When you use Just Image Converter:

  1. You select an image file from your device
  2. Your browser reads the file using the File API
  3. JavaScript converts the image to WebP format using Canvas API
  4. The converted image is stored temporarily in your browser's memory
  5. You download the result directly to your device
  6. When you close the page, all temporary data is cleared

At no point is your data sent to any server or external service.

Data Processing Location

All image processing occurs:

  • In your web browser (Chrome, Firefox, Safari, Edge, etc.)
  • On your device (computer, tablet, or phone)
  • Using client-side JavaScript code that you can inspect

The application is hosted on GitHub Pages as static HTML, CSS, and JavaScript files. GitHub Pages serves these files but has no ability to access, process, or store your images.

Technical Safeguards

We've implemented multiple security measures:

  • Content Security Policy (CSP): Prevents unauthorized scripts from running
  • No external resources: All code is served from the same domain
  • MIME type validation: Ensures only image files are processed
  • File size limits: Prevents memory exhaustion attacks
  • Rate limiting: Protects your browser from excessive processing

Compliance

Because we don't collect any personal data, Just Image Converter is inherently compliant with:

  • GDPR (General Data Protection Regulation)
  • CCPA (California Consumer Privacy Act)
  • PIPEDA (Personal Information Protection and Electronic Documents Act)
  • Other international privacy regulations

No consent banners, privacy settings, or data requests are necessary because there is no data collection to consent to.

Open Source

The complete source code is available on GitHub. You can review every line of code to verify our privacy claims.

We welcome security audits and privacy reviews from the community.

Browser Permissions

Just Image Converter only uses standard web APIs:

  • File API: To read files you explicitly select
  • Canvas API: To process and convert images
  • Blob API: To create downloadable files
  • Clipboard API: To copy images (only when you click "Copy")

We explicitly disable unnecessary permissions like camera, microphone, and geolocation.

Changes to This Policy

If we make changes to this privacy policy, we will update this page. Since we don't collect contact information, we cannot notify you directly of changes.
