Privacy Policy
Effective date: August 25, 2026
Who runs this site
This website is run by an individual, not a company. You can reach the operator at support@base64tools.online.
The short version
Your files and data stay in your browser. Every conversion on this site is performed locally on your device by your own browser. Files you open and text you paste never leave your device and are never collected. We use third-party analytics to understand overall site usage — they never receive your files, your file names, your input content or your conversion results.
What we collect
This site has no accounts, no registration and no contact forms. We do use the third-party analytics services listed below, which receive standard usage data such as pages visited, referring pages, approximate device and browser type, and how visitors interact with pages. None of these services receives the content you paste, drop or convert: every tool runs locally in your browser, and the analytics scripts never carry user content.
Third-party analytics services
This site uses the following analytics services. Each processes data under its own privacy policy:
- Google Analytics 4 (Google) — measures overall site usage such as page views, traffic sources and session counts. It sets cookies (including _ga) to distinguish visits. Privacy policy: https://policies.google.com/privacy
- Microsoft Clarity (Microsoft) — records how pages are used, including session replays of interactions such as clicks, scrolls and mouse movement. It sets cookies (including _clck and _clsk). Tool input and output areas on this site are masked, so the content you paste or convert is not captured in these recordings. Privacy policy: https://privacy.microsoft.com/en-us/privacystatement
- Ahrefs Web Analytics — a privacy-friendly, cookieless analytics service that does not set cookies or collect personal data. Privacy policy: https://ahrefs.com/privacy-policy
- Plausible — a cookieless analytics service that does not set cookies or collect personal data. Data policy: https://plausible.io/data-policy
None of these services is used for advertising, and this site loads no advertising scripts.
Hosting
This site is a static website hosted on Cloudflare Pages. Cloudflare, as the hosting and CDN provider, may process standard web server logs (such as IP addresses) according to its own privacy policy: https://www.cloudflare.com/privacypolicy/
Cookies and local storage
This site sets no cookies of its own. Two of the analytics services listed above set cookies — and only after you accept analytics cookies:
- _ga and related Google Analytics cookies (Google Analytics 4) — used to distinguish visits and count sessions.
- _clck, _clsk and related Clarity cookies (Microsoft Clarity) — used to link page views into sessions and to recognize returning visits for session replay.
Ahrefs Web Analytics and Plausible are cookieless and collect no personal data, so they load regardless of your choice.
Your consent choice is saved in your browser's local storage as a simple yes/no flag. It never contains your files, your file names or anything you paste or convert.
How to opt out
When you first visit, you can accept or reject analytics cookies. Google Analytics and Microsoft Clarity load only after you accept; rejecting keeps them off. You can change or withdraw your choice at any time using the Cookie settings link in the footer.
Ahrefs Web Analytics and Plausible are cookieless and collect no personal data, so they load regardless of your choice; they offer no per-user opt-out. You can block or delete cookies at any time in your browser settings, and every tool on this site works the same with analytics cookies blocked. To opt out of Google Analytics across websites, you can install Google's opt-out browser add-on: https://tools.google.com/dlpage/gaoptout. Blocking cookies or scripts from Microsoft domains disables Clarity.
Your rights and contact
Because this site collects no personal data beyond the analytics described above, there is generally very little for us to access, correct or delete. If you have a privacy question or request anyway, email support@base64tools.online.
Changes to this policy
If this policy changes, the updated version will be posted on this page with a new effective date. Any new analytics service or any new kind of data processing will be disclosed on this page before it goes live.
