Frequently Asked Questions
Why do I need to encode a URL?
URLs can only contain certain characters. Special characters like spaces, &, = must be percent-encoded to be transmitted safely over the internet.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes full URLs and preserves /, :, and ?. encodeURIComponent encodes individual parameter values and also encodes those characters.
Is my data sent to a server?
No. All encoding and decoding is done entirely in your browser — your data never leaves your device.
Can it handle Unicode characters?
Yes. Non-ASCII characters like Chinese, Arabic, or emoji are properly percent-encoded to their UTF-8 byte sequences.
