About URL Encoder Decoder
URL encoding converts special characters in URLs into a format that can be safely transmitted over the internet. Characters like spaces, &, =, ?, #, and non-ASCII characters are replaced with their percent-encoded equivalents. Our URL encoder and decoder handles both directions: encode a raw URL or string for safe use in query parameters, or decode a percent-encoded string back to human-readable form. Essential for web developers building APIs, working with query strings, and debugging URL-related issues.
Frequently Asked Questions
What characters need to be URL encoded?
Spaces, &, =, ?, #, %, +, and non-ASCII characters all need encoding.
What is the difference between URL encoding and Base64?
URL encoding replaces unsafe characters with % codes for use in URLs. Base64 converts binary to ASCII text. They serve different purposes.
Can it decode already-encoded URLs?
Yes — paste any percent-encoded URL or string and it will be decoded back to plain text.
Should I encode an entire URL or just the parameters?
Encode only the parameter values, not the full URL. Encoding slashes and the domain breaks the URL structure.
Does it support Unicode and emoji in URLs?
Yes — Unicode characters and emoji are converted to their UTF-8 percent-encoded form.
