The encodeURI() function encodes a URI by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two surrogate characters).

September 21, 2023 - In this article, we've covered the basics of character encoding in JavaScript, including the different encoding standards, how they work, and how to work with them in Node.js and web browsers. We've also covered some best practices for working with character encoding in JavaScript and provided tips and techniques for debugging encoding issues.

October 30, 2025 - The encodeURIComponent() function encodes a URI by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two surrogate characters).

October 2, 2025 - This article explains how to use btoa() to encode strings into Base64 and atob() to decode them back. We will also cover common applications for Base64 in web development and address the limitations of these functions, particularly when working with Unicode characters, providing a more robust solution for modern use cases. The tutorial also provides a method for handling non-ASCII text and explains the correct approach for Node.js ...

The TextEncoder.encode() method takes a string as input, and returns a Uint8Array containing the string encoded using UTF-8. js · encode(string) string · A string containing the text to encode. A Uint8Array object containing the UTF-8 encoding of the input string.

This extension allows you to encode strings in the JavaScript format (i.e. Unicode/Hex), similar to Burp's Convert-To but specifically for within JSON/JavaScript.

For the files section, this is partially irrelevant since files already contain the corresponding separators, but you can define which one to use for the "encode each line separately" and "split lines into chunks" functions.

Sometimes you have to send or output an image within a text document (for example, HTML, CSS, JSON, XML), but you cannot do this because binary characters will damage the syntax of the text document. To prevent this, for example, you can encode image to Base64 and embed it using the data URI.

Different encodings have different numbers of characters. At first, small tables like ASCII were enough for programmers.

June 17, 2026 - This guide will walk you through the primary URI encoding/decoding functions in JavaScript and the use cases for each.
