How imgshrnk ensures your privacy when compressing images using jSquash WebAssembly codecs.
Our compression tool uses jSquash WebAssembly codecs — running entirely in your browser. Images are compressed locally and never sent to a server, giving you full control over your files at all times.

2. How We Use Your Data
Collected data is used solely to improve our compression tool's functionality — such as optimizing the interface or supporting formats like JPEG, PNG, WebP, and AVIF. We do not sell, share, or misuse your information.
3. Data Security
Images are processed locally in your browser using WebAssembly, ensuring they never leave your device. Our Canvas API fallback maintains functionality without compromising security.
4. Cookies and Tracking
We may use cookies to track anonymous usage patterns such as compression frequency. You can manage cookie preferences through your browser settings at any time.
5. Third-Party Services
Third-party analytics tools may receive anonymized data to analyze usage trends, but no personal information or images are ever shared.
6. Your Rights
Since we don't store images or personal data, there's nothing to access or delete. Contact us at support@imgshrnk.com to opt out of analytics or with any questions.
7. Changes to This Policy
We may update this policy to reflect improvements or legal requirements. Changes will be posted here, effective immediately.
