How does the tool handle malformed percent-encoded sequences?

If an invalid percent-encoded string (like '%E0%A4%') is provided, PicoFix gracefully catches the error and explains where the invalid sequence occurred without crashing.

Are URLs logged or tracked?

No. All encoding and decoding runs client-side in your browser. No URLs, tokens, or query strings are sent to our servers or recorded in analytics.

Component vs Full URI Percent Encoding

Understanding when to use encodeURIComponent versus encodeURI.

Component Mode (Query Strings)

Uses encodeURIComponent() to escape all special delimiters including &, =, ?, and /. Essential when injecting user search terms, auth tokens, or redirect URLs into query parameters.

Full URI Mode (Preserve Structure)

Uses encodeURI() to preserve protocol schemes (https://), slashes, ports, query delimiters, and fragment hashes while escaping whitespace and non-ASCII characters.

Zero Data Tracking

URLs frequently contain confidential OAuth tokens, session IDs, and internal domains. PicoFix never logs or transmits user strings to remote servers or analytics.

URL Encoder & Decoder FAQs

Helpful answers to common image compression questions.

Component mode (encodeURIComponent) encodes all special characters including '/', '?', and '&', making it ideal for query string parameter values. Full URL mode (encodeURI) preserves the protocol and domain structure while escaping spaces and invalid characters.
