Privacy Policy
Last updated: August 22, 2026
This Privacy Policy explains how BlockMosaic(“we”, “us”) handles information when you use this website and its tools. By using the site, you agree to this policy.
Your images stay on your device
All image conversion happens locally in your browser. The pictures you upload are never sent to our servers — they are read, processed and previewed entirely on your own device, and discarded when you close or refresh the page. We have no access to them and do not store them anywhere.
Information we collect
We do not require an account, and the tools do not ask for your name, email address, phone number, or precise location. Like most websites, our hosting provider may process basic request data such as an IP address, browser type, requested URL, and timestamp to deliver the site, maintain security, and diagnose errors. We may also use the following third-party services:
- Analytics. We may use Google Analytics 4 to understand aggregate, anonymous usage, such as pages viewed, approximate region, device type, and interaction events. This helps us understand which tools need improvement. We do not add names, email addresses, phone numbers, or other directly identifying information to analytics events or page URLs.
- Advertising. We may display ads through Google AdSense. Google and its partners may use cookies or device identifiers to serve and measure ads.
Cookies
Cookies are small files stored by your browser. We and our service providers (Google Analytics, Google AdSense) may use cookies for analytics and advertising. You can disable cookies in your browser settings; the tools on this site will continue to work without them.
Personalized advertising and your choices
If advertising is enabled, Google and its advertising partners may use cookies, mobile advertising identifiers, or similar technologies to select, personalize, limit, and measure ads. Interest-based advertising may use information from visits to this site and other sites. We do not receive a list of the websites you visited or use sensitive information to create advertising audiences.
You can manage personalized advertising in Google's My Ad Center and learn about other opt-out options at YourAdChoices. Blocking or rejecting advertising cookies may make ads less relevant, but it does not stop all ads.
Consent for visitors in the EEA, United Kingdom, and Switzerland
Where required by Google's user consent policy or applicable law, we will use a Google-certified consent management platform before storing or accessing non-essential cookies for advertising or analytics. The consent message will let eligible visitors accept, reject, or manage available choices. You can change a prior choice through the privacy controls displayed on the site when the consent platform is active.
Location information
The site does not request access to your device's GPS or other precise location sensors. Analytics and advertising providers may infer a broad area, such as a country or city, from an IP address. We do not use inferred location to identify an individual. If a future feature needs precise location, we will explain why and ask for permission before collecting it.
Google AdSense & the DoubleClick cookie
Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits. You can opt out of personalized advertising by visiting Google Ads Settings. For more on how Google uses data, see Google's policy.
Children's privacy
This site is general-audience and not directed at children under 13. We do not knowingly collect personal information from children.
Data retention and security
We do not retain the images you open in the converter because they never leave your browser. Analytics, advertising, hosting, and security providers retain the limited data they process under their own settings and policies. We use HTTPS to protect data while it travels between your browser and the site, but no internet service can guarantee absolute security.
Third-party links
Our guides may link to external websites. Their privacy practices are controlled by their own operators, not by BlockMosaic. Review an external site's policy before sending it personal data or downloading software.
Changes to this policy
We may update this policy from time to time. Changes will be posted on this page with a new “last updated” date.
Contact
Questions or requests about this policy can be sent through our Contact page. Include the relevant page URL and do not send sensitive identification documents unless we specifically explain why they are required.
