How it works
Encode or decode Base64 in three steps
ToolNoova converts compatible text into Base64 or attempts to turn Base64 data back into readable text.
Choose an action
Select Encode Base64 or Decode Base64 depending on the result you need.
Review and copy
Check the generated result and copy it to your clipboard when ready.
Base64 features
A simple utility for encoded text
Base64 is commonly used when binary or textual data must be represented using a limited set of readable characters.
Text encoding
Convert supported plain text into a Base64-encoded character string.
Base64 decoding
Attempt to convert valid Base64 data back into readable text.
Instant results
Generate encoded or decoded output without installing additional software.
Copy output
Copy the generated result for use in code, testing or documentation.
Clear controls
Remove the current input and output before starting another conversion.
Browser based
Use the tool through a modern browser on desktop, tablet or mobile devices.
Example
Base64 encoding example
Encoding changes how data is represented. It does not automatically encrypt or secure the original information.

Frequently asked questions
Base64 Encoder & Decoder FAQ
Is the ToolNoova Base64 tool free?
Yes. The current Base64 encoder and decoder is free to use and does not require registration.
What is Base64?
Base64 is a method of representing data using letters, numbers and a small number of additional characters.
Is Base64 secure or encrypted?
No. Base64 is an encoding format, not an encryption method. Encoded content can normally be decoded easily.
Why is Base64 output longer than the original text?
Base64 uses a restricted character set to represent the source data, which normally increases the total output length.
Why does Base64 sometimes end with equals signs?
One or two equals signs may be added as padding so the encoded output fits the required Base64 block structure.
Why does decoding fail?
The input may contain invalid characters, incorrect padding, missing data or content that was not originally encoded as compatible text.
Can Base64 encode passwords safely?
No. Passwords should be protected using appropriate cryptographic hashing and secure storage practices, not Base64 encoding.
Does ToolNoova store my Base64 data?
The current tool is designed to process entered text inside your browser and does not require a ToolNoova account.
