Security
Remove Metadata Online is built with security-first principles. Here is how we protect your files and privacy.
File Validation
Every uploaded file is validated by extension, MIME type, and magic bytes. Executable and dangerous files are always rejected.
Secure Storage
Files are stored outside the public web directory with randomly generated UUID filenames. No direct URL access is possible.
Auto-Delete
All files are automatically deleted after 5 minutes — both original uploads and processed results.
Signed Tokens
Download links use HMAC-signed tokens with 5-minute expiry. No unauthorized access to processed files.
SSRF Protection
The remote URL tool blocks private IP ranges, localhost, cloud metadata endpoints, and validates all redirects.
Rate Limiting
Processing requests are rate-limited per IP to prevent abuse. Suspicious patterns trigger additional protection.
Additional implementation details
- Processing engines run with configured timeouts so a single file cannot occupy a worker indefinitely.
- Archives, scripts, executables, HTML pages, and unsupported file types are rejected instead of being extracted or executed.
- Remote URLs are checked before and after redirects, with private networks, localhost, cloud metadata endpoints, and oversized files blocked.
- Download responses are served as attachments with private tokens, no-store cache behavior, and noindex headers.
- Temporary files use random server filenames and are cleaned by automatic expiration plus the recommended Hestia cleanup cron.
