EXIF Metadata Remover - Security
How we protect your data and ensure safe metadata removal
Content Security Policy (CSP)
We implement strict Content Security Policy headers to prevent cross-site scripting (XSS) attacks and restrict resource loading to trusted sources only. This ensures malicious scripts cannot be injected into your browser session.
Security Headers
We use HTTP security headers including X-Content-Type-Options and X-Frame-Options to prevent MIME type sniffing and clickjacking attacks.
Permissions Policy
Unnecessary browser features (camera, microphone, geolocation, payment APIs, USB, and sensors) are explicitly disabled to minimize attack surface and protect your privacy.
Filename Sanitization
All uploaded filenames are sanitized to prevent path traversal attacks, special character injection, and other filename-based exploits. Dangerous characters are removed or replaced.
Secure Memory Cleanup
After metadata removal is complete, image data is explicitly overwritten with zeros before being cleared from memory. This prevents data recovery attacks.
Image Format Validation
Only supported image formats (JPEG, JPG, PNG) are accepted. Unsupported file types are rejected at upload time to prevent processing of potentially dangerous files.
File Signature Verification
We verify the "magic bytes" (file signature) of uploaded images to ensure they match their declared type. This prevents users from uploading disguised or corrupted files that could cause processing errors.
Disabled Browser Autocomplete
File input fields have autocomplete disabled to prevent your browser from caching sensitive filenames or paths in your browser history.
Client-Side Processing Only
All metadata removal and image processing are performed entirely in your browser using JavaScript. Your images are never transmitted to any server, ensuring complete end-to-end privacy and security.
No External Communication
Your image contents and metadata are never uploaded to a server or sent to external APIs for processing. This page may load third-party resources (for example, open-source libraries from CDNs and advertising scripts) which can receive standard web request data (like IP address and user agent), but they do not receive your images or metadata because processing runs locally in your browser.
