How to Encode and Decode Base64, URL, and HTML Entities

Why encoding matters

Encoding converts data into a format that can be safely transmitted or displayed in different contexts. Base64 embeds binary data in text formats, URL encoding ensures special characters work in web addresses, and HTML entities prevent rendering issues in web pages. Decoding reverses the process to recover the original content.

Common encoding use cases

Embedding images in CSS or HTML as Base64 strings, encoding API credentials for HTTP headers, sanitizing user-generated URLs, converting special characters for email links, and debugging encoded payloads in web applications. Every developer encounters these tasks regularly.

How to use the Encoder / Decoder

Open the Encoder / Decoder tool, paste your text into the input field, and select the encoding type. The tool instantly shows the encoded or decoded result. You can switch between encoding and decoding modes and choose from Base64, URL encoding, HTML entities, and more. Copy the result with one click.
