What does More Base64 Tools do?

A general Base64 workbench: encode text or files to Base64, or decode Base64 back to text or a downloadable file.

Base64 turns any data into plain letters and digits so it can travel safely in JSON, email, URLs or HTML. It is an encoding, not encryption — anyone can decode it.

Good to know

  • Base64 makes data about a third larger (every 3 bytes become 4 characters).

Your privacy

Your file is opened and processed by your own browser — it is never uploaded. That also means big files use your device’s memory, so very large files can be slow on older phones.

Frequently asked questions

Is More Base64 Tools free?

Yes. More Base64 Tools is completely free, with no sign-up, no watermark and no daily limit.

Is the data I paste sent to a server?

No. Conversion runs in JavaScript inside this browser tab and nothing you paste is sent or stored. Even so, avoid pasting live passwords, API keys or private customer data into any website.

Why do I get an error?

Almost always the input isn’t quite valid: a missing comma or quote in JSON, an unclosed tag in XML, or a tab in YAML. The error message shows where parsing stopped — fix that spot, or press “Load example” to compare with input that works.

Does it work on my phone?

Yes. It works in any modern browser on Android, iPhone, tablets and computers — nothing to install.
