Privacy policy

Your input belongs to you. Base64 conversions happen locally in your browser.

Last updated: October 19, 2026

Data you enter

Text and files you provide to the encoder or decoder are processed on your device using browser APIs. They are not sent to or stored on a Base64 Studio server. Clearing the page removes the converter's current input and output from the page.

Analytics

Cloudflare Web Analytics is active on every page. It provides aggregated statistics about site visits and does not set cookies.

Advertising and cookies

The production website uses Google AdSense to show advertisements. Google and its partners may use cookies or similar technologies, and may process information such as your IP address, browser and device data, and ad interactions, to provide, measure, and personalize ads. Ads are subject to Google's approval and ad availability.

Learn more in Google's advertising technologies and privacy information. Depending on your location, consent may be required before advertising technologies are used. No consent-management platform is currently integrated into this site.

Hosting and technical data

The site is hosted on Cloudflare Pages. Cloudflare may process standard request and security data, such as your IP address, to deliver and protect the site.

Security reminder

Base64 is an encoding format, not encryption. Do not use it to secure confidential information. Only decode content from sources you trust, and do not run files just because they have been Base64-decoded.

Privacy requests

For privacy questions or requests, email [email protected]. Please do not include passwords, tokens, or private files in your email. Replies are not guaranteed to be immediate.

Policy updates

This policy may be updated if the site's features change. The current version will always be available on this page.
