ANFA LAYER
Strip all metadata from your images and seal with SHA-256 cryptographic proof.
100% private — processed locally in your browser.
Click or drag file to upload
Supports JPEG, PNG, WebP, TIFF, AVIF, HEIC (Max 10MB)
How ANFA LAYER Works
1. Upload Locally
Your files never touch a server. Processing happens 100% inside your browser session.
2. Clean & Hash
We redraw the image on canvas to purge hidden tags, then calculate a unique fingerprint.
3. Issue Proof
A digital seal (.anfa.json) is generated containing the hash to prove later authenticity.
Securing the visual web, one pixel at a time.
The cryptographic sealing logic used here is part of the ANFA Layer protocol. Integrate verifiable image integrity into your own projects with our NPM package.

Who Uses ANFA LAYER?
From investigative journalists to medical professionals — anyone who shares images professionally needs ANFA LAYER.
Journalists & Whistleblowers
Share sensitive evidence photos without revealing your GPS location, device model, or the exact time of capture. Protect your sources and yourself.
Medical Professionals
Strip patient-identifying EXIF data before sharing diagnostic images for research or consultation. Stay HIPAA compliant by default.
Legal & Forensics
Generate cryptographic proof that evidence photos have not been altered since capture. The SHA-256 seal creates an unbreakable chain of custody.
Privacy Advocates
Every photo you take with a smartphone contains hidden data. Remove GPS coordinates, device serial numbers, and software fingerprints before sharing online.
Developers & Security Teams
Integrate ANFA Layer into your pipeline with npm install anfa-layer. Verify image integrity programmatically with timing-safe SHA-256 comparison.
Photographers & Creators
Share portfolio work without leaking your camera model, lens data, or shooting location. Your creative metadata stays private.
What is Image Metadata and Why is it Dangerous?
What EXIF data contains:
Exact latitude and longitude of where the photo was taken
Camera make, model, and unique serial number
Exact date and time — down to the second
Editing software used — Photoshop, Lightroom, etc.
WiFi network name in some smartphone images
Focal length, aperture, shutter speed, ISO
What ANFA LAYER removes:
All camera and device information completely erased
Adobe and editing software metadata removed
News agency and copyright metadata stripped
All location data — latitude, longitude, altitude
Embedded preview thumbnails that may contain original data
Any non-standard data appended to the image file
Frequently Asked Questions
Is my image uploaded to any server?
No. ANFA LAYER processes everything 100% locally inside your browser using the Canvas API and Web Crypto API. Your image never leaves your device. There is no backend server.
What is the .anfa.json seal file?
The seal file contains a SHA-256 cryptographic hash of your clean image, along with a timestamp and version info. If even one pixel of the image changes after sealing — the hash will not match and tampering will be detected.
What image formats are supported?
ANFA LAYER supports JPEG, PNG, WebP, TIFF, AVIF, GIF, BMP, and HEIC. Most formats are processed natively. GIF and BMP are converted to PNG for standardized metadata-free output.
Does stripping metadata reduce image quality?
No. ANFA LAYER redraws the image on an HTML5 canvas at full resolution. JPEG output uses 95% quality setting. PNG output is fully lossless. The only thing removed is the hidden metadata.
Can I use ANFA LAYER in my own application?
Yes. ANFA Layer is open source and available on npm. Run npm install anfa-layer to add it to your Node.js project. Full API documentation is available on GitHub at github.com/Mpitafi7/ANFA-LAYER.
What is SHA-256 and why does ANFA use it?
SHA-256 is a cryptographic hash function that generates a unique 64-character fingerprint for any file. If the file changes by even one bit — the fingerprint completely changes. ANFA uses SHA-256 via the browser's built-in Web Crypto API for tamper detection.
Is ANFA LAYER free to use?
Yes. ANFA LAYER is completely free — both this web tool and the npm package. It is MIT licensed open source software. No registration, no subscription, no limits.
