Zero-Knowledge Client Architecture

Privacy Policy

Last updated: October 15, 2026. OnlineImageCompresion was architected on a fundamental premise: your images and private documents must never leave your computer or phone.

Executive Privacy Summary

  • ✓Zero Image Uploads: Photos, graphics, and documents are compressed 100% inside your browser's local memory.
  • ✓No Remote Storage: There is no cloud database or backend upload API connected to the compression engine.
  • ✓Zero Ad Trackers: We do not deploy surveillance cookies, advertising beacons, or sell your behavior to data brokers.
  • ✓Instant Memory Flush: When you refresh or close the tab, all image buffers are automatically garbage-collected by your browser.
Data Processing

1. Information We Do Not Collect

Unlike conventional image compressors that transmit raw files across remote networks to external server clusters, OnlineImageCompresion executes every operation client-side using JavaScript, WebAssembly, and the HTML5 Canvas API.

As a consequence of our zero-egress architecture:

  • We cannot view, intercept, or access your images.
  • We do not record filenames, EXIF location metadata, camera serial numbers, or image dimensions.
  • We do not require account registration, email addresses, or credit cards to use any feature.
Technical Proof

2. The Offline Verification Test

You don’t have to take our word for it. You can independently verify our privacy guarantee in less than 30 seconds:

  1. Load onlineimagecompresion.com in your browser.
  2. Disconnect your device from the Internet (turn off Wi-Fi or turn on Airplane Mode).
  3. Drop your most sensitive images onto the compressor dropzone.
  4. Observe that image optimization, slider comparison, and bulk ZIP generation operate instantaneously with zero network activity.
Client Storage

3. Local Storage & Cookies

We use strictly necessary browser localStorage solely to remember your aesthetic preferences (specifically whether you prefer Dark Mode or Light Mode).

We do not use tracking cookies, retargeting pixels, or third-party fingerprinting scripts.

Compliance

4. GDPR, CCPA/CPRA & HIPAA Suitability

Because raw personal files and image data never leave your local client workstation, OnlineImageCompresion provides inherent structural compliance:

  • EU GDPR: No international transfer of personal data occurs. There are no data sub-processors handling your image payloads.
  • California CCPA / CPRA: We do not sell or share personal information as defined by California privacy statutes.
  • Healthcare & Financial Confidentiality: Medical records, signed contracts, identity scans, and proprietary corporate diagrams can be safely processed without violating data segregation mandates.
Security Measures

5. Data Security & Zero-Egress Architecture

The website is served over end-to-end encrypted HTTPS using modern TLS protocols with strict HTTP Strict Transport Security (HSTS) headers. Your files remain isolated inside your browser process's sandbox, protected by standard same-origin security policies.
