Frequently Asked Questions (FAQ)
Does it support UTF-8 characters?
Yes. The tool perfectly handles accents, emojis, and multi-byte characters without crashing during Base64 encoding or decoding.

About the Encoder / Decoder
The Base64 / URL / HTML Encoder by Grab-Kit is a free online tool designed for web developers, SEO specialists, and backend engineers. Data encoding is a fundamental part of web development: Base64 is used to embed binary images directly into HTML or send JSON payloads in HTTP headers; URL encoding (percent-encoding) ensures that special characters like spaces or & don't break query parameters; and HTML entities prevent XSS attacks by converting < and > into < and >. Our tool brings these three essential encoders together in one clean interface.
Using the tool is incredibly straightforward. Select your desired encoding mode using the tabs (Base64, URL, or HTML Entity). Paste your text into the "Input" box on the left. Click "Encode" to transform your text into the encoded format, or paste encoded text and click "Decode" to reveal the original string. The tool features full UTF-8 support, meaning it perfectly handles accents, emojis, and multi-byte characters without crashing. You can then click "Copy" to instantly copy the result to your clipboard.
