About this tool

Converts binary data into a plain text string format known as Base64, and performs the reverse process to retrieve the original data. This utility accepts input of various types, including standard character sets and Unicode characters, ensuring accurate encoding even with complex symbols or international scripts. Users simply paste their encoded or raw data into the designated field, and the tool instantly generates the corresponding output in the opposite format. Developers, web designers, and students frequently utilize this encoder-decoder for data transmission tasks. It is particularly helpful when transferring non-text data, such as images or files, through mediums that only support ASCII text characters.

HTML Entity Encoder3 options

Developers and web designers often need to convert special characters into their corresponding HTML entities to ensure proper rendering across different browsers. HTML Entity Encoder provides a reliable method to transform sensitive characters—such as angle brackets, ampersands, and quotes—into standardized code that prevents browsers from misinterpreting them as functional HTML tags. This process is essential for anyone looking to display raw code snippets on a webpage or securely manage user input within a web application. The utility also integrates XSS prevention analysis, offering insights into how specific encoding choices contribute to site security. By substituting potentially malicious characters with safe entities, it helps mitigate the risk of cross-site scripting attacks that target vulnerabilities in data handling. Users can switch between encoding and decoding functions to verify their data or restore entities to their original plaintext format for editing and review.
