About Base64 Encoder / Decoder
Base64 shows up everywhere once you start working with data, from embedding images in HTML to passing tokens in API headers and reading email attachments. The problem is that raw Base64 looks like meaningless gibberish, and encoding or decoding it by hand is impossible. This tool turns plain text into Base64 and decodes Base64 strings back into readable text in a single step.
Paste your text or your encoded string, choose the direction, and the result appears right away, ready to copy. There is nothing to install and no account to create, and your input is processed in the browser rather than stored on a server. Whether you are debugging an API response or encoding a small snippet, it is a quick, free, and private way to handle Base64.
Common uses
- Decoding a Base64 string from an API response to see what data it actually contains
- Encoding a small piece of text or a token before sending it in a request
- Inspecting the payload of a JWT or other encoded header value during debugging
- Converting text into Base64 to safely embed it where binary-unsafe formats are required
- Quickly checking whether a suspicious-looking string is just Base64-encoded text

FAQ
Can I both encode and decode with this tool?
Yes. Enter plain text to encode it to Base64, or paste a Base64 string to decode it back to readable text.
Is my text sent anywhere?
The conversion happens in your browser, so your input stays on your device and nothing is stored after you leave.
Why does my decoded text look broken?
That usually means the input was not valid Base64, or it encoded binary data rather than plain text. Double-check that you pasted the full, correct string.
Can I use Base64 Encoder / Decoder on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
