Privacy Policy

Last updated: June 24, 2026

Short version: This is a client-side tool. The text and files you encode or decode are processed entirely in your browser and are never uploaded to, stored on, or seen by our servers.

This Privacy Policy explains how this website ("we", "us", "the site") handles information when you use our online Base64 encoder and decoder. By using the site, you agree to the practices described here.

1. The content you convert

All encoding and decoding happens locally in your web browser using JavaScript. Any text you type or paste, and any file you upload or drag into the tool, is processed on your own device. This content is not transmitted to our servers, not logged, and not stored by us.

2. Information stored on your device

To improve your experience, the tool may save your preferences (such as the selected mode, character set, and option toggles) in your browser's localStorage. This data stays on your device, is not sent anywhere, and can be cleared at any time by clearing your browser storage.

3. Analytics

We may use privacy-respecting analytics to understand aggregate, anonymous usage (for example, page views and general location at the country level). These analytics do not identify you personally and do not access the content you convert.

4. Advertising and cookies

This site may display advertising provided by third-party ad networks, including Google AdSense. These networks may use cookies and similar technologies to serve and measure ads, and in some cases to personalize them based on your prior visits to this and other websites.

Google's use of advertising cookies is described in Google's advertising policies.
You can opt out of personalized advertising via Google Ads Settings or aboutads.info.

5. Third-party links

The site may link to other websites we operate or to third-party resources. We are not responsible for the privacy practices of external sites; please review their policies separately.

6. Children's privacy

This site is a general-purpose developer utility and is not directed at children under 13. We do not knowingly collect personal information from children.

7. Your choices

Clear your browser storage to remove saved preferences.
Use your browser or ad-settings controls to manage cookies and personalized ads.

8. Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above.
