Cookie Policy

1. What Are Cookies and Local Storage?

Cookies are small text files placed on your device by web servers when you navigate to web pages. Modern web browsers also provide advanced client-side storage technologies, such as IndexedDB and Service Worker Cache Storage, designed to improve web application performance.

2. How Tocompress Uses Local Storage

Tocompress uses client-side storage strictly for essential operational efficiency:

Service Worker Cache: Caches application assets (HTML, CSS, JavaScript) so subsequent page visits load instantly.
IndexedDB WASM Caching: Stores compiled WebAssembly codec binaries (MozJPEG, OxiPNG, WebP) locally so they do not need to be downloaded again on every image upload.

3. Third-Party Advertising Cookies (Google AdSense)

We use Google AdSense to serve advertisements on our informational and educational guide pages. Google and its third-party advertising partners use cookies (such as the DoubleClick cookie) to serve ads based on a user’s prior visits to this website and other sites across the internet.

These cookies help deliver relevant advertising and prevent the same ad from repeatedly appearing to a user.

4. How to Control or Disable Cookies

You can manage, restrict, or delete cookies at any time through your browser settings:

Opt out of personalized advertising by visiting Google Ads Settings.
Opt out of third-party vendor advertising cookies via www.aboutads.info.
Adjust your browser settings (Chrome, Safari, Firefox, Edge) to block third-party cookies entirely.

Disabling advertising cookies will not interfere with the core image compression or resizing features of Tocompress.
