Encoding Tools
Encode and decode data using common web formats. Our Base64 encoder/decoder supports text and binary data, while the URL encoder handles percent-encoding for query strings and URI components. All processing happens in-browser with zero server contact.

Frequently Asked Questions
What is Base64 encoding used for?
Base64 encoding converts binary data into an ASCII string, making it safe to transmit over text-based protocols like HTTP, email (MIME), and JSON. Common uses include encoding images, credentials in HTTP headers, and data URIs.
What is the difference between URL encoding and Base64 encoding?
URL encoding (percent-encoding) replaces special characters in URLs with % followed by a hex code. Base64 encoding converts arbitrary binary data into alphanumeric text. They serve different purposes — URL encoding is for safe URL transmission; Base64 is for embedding binary in text formats.
Is my data sent to a server when I encode or decode?
No. All encoding and decoding happens entirely in your browser using JavaScript. Your data is never sent to any server.
Does Base64 encoding encrypt my data?
No. Base64 is an encoding scheme, not encryption. It transforms data into a different format but does not provide any confidentiality — anyone can decode it.
