Enter Your Text
Type or paste the text you want to encode or decode into the main input area.
Select Encoding/Decoding Method
Choose your desired method from the "Encoding Method" options:
- Base64: Encodes text into a Base64 string or decodes a Base64 string back to text. Commonly used for transmitting binary data over text-based channels.
- URL: Encodes text for safe use in URLs (Percent Encoding) or decodes URL-encoded text. Replaces unsafe characters with
%xxsequences. - HTML Entities: Encodes special characters into HTML entities (e.g.,
<becomes<) or decodes HTML entities back.
Click "Encode" or "Decode"
Press either the "Encode" button or the "Decode" button , depending on the action you want to perform.
View Processed Text
The processed text will appear in the "Encoded Text" or "Decoded Text" output area. Errors (e.g., invalid input) will be shown in the relevant output area.
Copy Your Output
Use the "Copy Encoded" or "Copy Decoded" button to easily copy the result to your clipboard.
Pro Tip: Ensure the input text format matches the selected decoding method. For example, trying to decode plain text as Base64 will result in an error. Use the "Clear" button to quickly reset.
Secure Data Handling
Encode sensitive data with Base64 for transmission or storage, or decode it to retrieve the original information.
Web Development Aid
URL encode parameters for web requests or decode them for processing. HTML entity encoding prevents XSS and display issues.
Versatile Methods
Supports common encoding schemes like Base64, URL (Percent) encoding, and HTML entities, covering a wide range of use cases.
Developer Friendly
Quickly test encoding/decoding logic or prepare/inspect data without writing custom scripts for common tasks.
Safe Text Display
Use HTML entity encoding to safely display user-generated content on web pages, preventing code injection.
Instant Results
Get immediate encoding or decoding results directly in your browser without server-side processing delays.
What is Base64 encoding?
Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It's commonly used to encode data that needs to be stored and transferred over media that are designed to deal with text, such as email or HTML.
What is URL (Percent) encoding?
URL encoding, also known as Percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. It's used to ensure that all characters in a URL are valid and can be correctly transmitted and interpreted. Unsafe characters (like spaces, &, =, ?) are replaced by a "%" followed by two hexadecimal digits that represent the ASCII value of the character.
What are HTML Entities?
HTML entities are pieces of text ("strings") that begin with an ampersand (&) and end with a semicolon (;). They are frequently used to display reserved characters (which would otherwise be interpreted as HTML code) or characters not easily typed on a standard keyboard. For example, < is used for "<", and & is used for "&".
Why am I getting a decoding error?
Decoding errors usually occur if the input text is not a valid string for the selected decoding method. For example:
- Trying to decode plain text as Base64.
- Providing an improperly formatted Base64 string (e.g., contains invalid characters or incorrect padding).
- Trying to decode a URL string that is not actually percent-encoded.
Does this tool handle UTF-8 / non-English characters correctly?
Yes, for Base64 encoding/decoding, the tool correctly handles UTF-8 characters by first converting the text to a UTF-8 byte stream before Base64 encoding, and vice-versa during decoding. URL encoding also correctly processes UTF-8 characters. HTML entity encoding will convert special Unicode characters into their respective named or numeric entities.
Is my data secure when using this tool?
