Base64 text converter
Prepare text for transport or inspect encoded values.
How it works
Unicode text is converted through UTF-8 before Base64 encoding and reversed during decoding.
Technical limitation
Base64 is an encoding, not encryption; it provides no confidentiality.
Privacy
Input stays in this browser and is not intentionally uploaded.
A practical guide to Base64 text converter
Encode Unicode text to Base64 or decode Base64 into readable text. This page handles one focused task so you can reach a result without creating an account. The core operation runs in the current browser unless an external resource is clearly identified.
How to get a reliable result
- Begin with a clean source value or file and confirm that every selected unit and option matches your goal.
- Run the tool, then compare the result with the original requirement instead of relying only on a success message.
- Copy or download the output and test it in the destination where it will actually be used.
Limitations and good practice
Browser tools reduce repetitive work, but the final output still needs human review. Keep an untouched copy of important source material. Browser support, rounding, source quality, encoding, and platform rules can affect results.
Frequently asked questions

Should I verify the output?
Yes. Review calculations, code, files, and images before using them for financial, legal, accessibility, security, or production decisions.
