Terms of Service

Last updated: October 2026

These terms set out the basis on which you may use base64deco.com (the "Site"). Using it means accepting them; if you do not accept them, do not use the Site.

Base64Deco is a Base64 encoder and decoder: it converts text to and from Base64 with full UTF-8 support for Chinese characters and emoji, and auto-detects which direction you want. In practice, it encodes the bytes of the string in UTF-8 first and then groups them into 6-bit chunks for the Base64 alphabet, which is why non-ASCII text survives intact instead of becoming mojibake. This page should be read with that tool in mind, because the limits described apply to what it computes.

Practically, all the calculation needs is the text or Base64 string you paste. Typical reasons people open Base64Deco include checking what a Base64 blob actually contains, and in every case the work happens on the visitor's own device rather than ours.

About this Site and its tools

This Site is a free, browser-based Base64 encoder and decoder. Its output is produced from your input using the stated method and is provided for information and education, not as advice. Developer tools produce output for use in your own work, and you remain responsible for reviewing and testing it.

No professional relationship

No professional relationship arises from your use of the Site, and any decision you base on a result is your own responsibility.

How you may use the Site

You are free to use the Site for your own purposes, business included. Prohibited: attacking or overloading it, scraping at a rate that harms service, misrepresenting it as yours, and any illegal use.

Content ownership and license

Unless credited otherwise, the Site's design, writing and code are ours or used under license. Linking to any page is welcome; copying large portions of the content needs our written consent.

How the Site is funded

Third-party adverts keep the Site free and external links appear for convenience. We vouch for neither, and neither can change an output.

Changes and downtime

There is no uptime promise: tools and pages may be altered, suspended or withdrawn without notice, and the Site is offered as it stands.

Limitation of liability

As far as legally permitted, our liability is excluded for indirect or consequential damages and for any decision taken on the strength of a result produced here.

Governing law

The terms are governed by the law of the jurisdiction in which the Site operator is established, conflict-of-law rules aside.

Responsibility for tool output

Treat output as a starting point rather than a finished artefact. Review, adapt and test it yourself; responsibility for anything that ships rests with you, not with the tool.

Accuracy

Correctness is a goal, not a warranty: results may contain errors and the content may lag changes in the field. Where the underlying method has a margin of error, read the output accordingly.
