Metadata Tools
Our Mission & Technology

About Us

We believe that privacy in the digital era should not require high-cost enterprise software or compromising security by uploading your personal files to unknown third-party cloud servers.

💻

100% In-Browser

Powered by WebAssembly and Web Workers. Your files are processed directly on your computer or phone CPU—never uploaded to any remote server.

🛡️

Zero-Knowledge

We physically cannot see, inspect, or retain your photos, documents, or videos. When you close the browser tab, your session memory is completely wiped.

⚡

Unlimited & Free

No sign-ups, no subscriptions, no watermarks, and no artificial file size limits. Clean, inspect, and edit your metadata with total peace of mind.

The Hidden Danger of Digital Metadata

Every time you take a photo with your smartphone or camera, save a PDF document, or record an audio memo, your device invisibly attaches dozens of hidden technical and personal tags known as metadata.

This hidden data often includes:

📍 Precise GPS Coordinates: Pinpointing the exact street, building, and altitude where a photo or video was captured.
📱 Device Identifiers: Make, exact model, unique lens serial numbers, and firmware versions.
👤 Personal Identity: Author names, company domains, email addresses, and computer username pathways.
🕒 Chronological Timestamps: Exact creation dates, modification times, and editing software history.

When sharing files online, submitting job applications, publishing portfolio photos, or providing investigative documents, leaking this information can compromise your physical security, disclose source confidentiality, or reveal private business details.

Why Traditional "Online Tools" Pose a Risk

Almost all conventional online metadata removers work by having you upload your confidential files to their private cloud servers. Once your files reach their servers, you have no way of knowing:

  • How long your files remain stored on their hard drives.
  • Whether employees or automated algorithms inspect your contents.
  • Whether your sensitive media might be leaked in a database breach or shared with third-party advertising partners.

Free Metadata Tools solves this once and for all. We built an application that delivers the convenience of a modern web interface with the bulletproof security of an offline desktop utility.

How Our Client-Side Architecture Works

WebAssembly (WASM)

We compile powerful C/C++ libraries (such as QPDF for PDF manipulation) into high-speed WebAssembly binaries that execute at near-native speed directly in your browser.

Dedicated Web Workers

Metadata extraction and scrubbing tasks run on background threads (Web Workers). This keeps your user interface buttery smooth while batch-processing gigabytes of media without freezing your browser.

Direct Cloud Integrations

When using Google Drive or Dropbox, communication happens strictly between your browser and the cloud provider's official HTTPS endpoints using OAuth 2.0. No middleman server ever touches your data.
