ToolKB Security

At ToolKB, we take security seriously. We have designed our tools with a privacy-first, secure architecture intended to keep your files safe.

Local Image Processing

Your files stay private.

The current ToolKB image compressor operates entirely within your web browser. When you select a file to compress or resize, the processing happens locally on your device. Your image files are not intentionally uploaded to our servers, ensuring your sensitive documents remain under your control.

Input Validation & Restrictions

To protect both your browser and our infrastructure, we enforce strict validations on the files processed by our tools:

• Format Restrictions: We only accept standard, safe image formats (JPG, PNG, WebP) and actively reject potentially malicious formats (such as SVG).
• Resource Protections: Our application implements limits on file sizes and image dimensions to prevent browser crashes and resource exhaustion (such as decompression bombs).
• Processing Limits: Compression operations are mathematically bounded to ensure they complete in a reasonable timeframe without freezing your device.

Infrastructure Security

We rely on modern, secure infrastructure (such as Vercel) to host our website. We monitor our dependencies for security updates and enforce strict Content Security Policies (CSP) and security headers to prevent cross-site scripting (XSS) and clickjacking.
