How do I encode text with URL Encoder Online?

Type or paste your input into URL Encoder Online, click Encode, and copy the encoded result. Decoding uses the same tool in reverse — paste the encoded string, click Decode, get the original text back.

Is Base64 (or hex, or URL encoding) encryption?

No — encoding is not encryption. Base64, hex, URL-encoding, and HTML-entity encoding transform data into a different representation so it can travel safely through systems that only accept certain characters (URLs, emails, HTTP headers). Anyone can decode it. For actual secrecy, use AES or another real cipher.

When should I use URL encoding vs HTML entity encoding?

URL encoding (percent-encoding) is for query strings, path segments, and form values — it escapes characters like spaces (%20), &, and =. HTML entity encoding is for content that goes inside HTML — it escapes , &, and " so browsers render them as literal text instead of parsing them as markup.

Does URL Encoder Online change my original data?

Encoding is a lossless, reversible transformation. Encode then decode and you get exactly the same bytes back — nothing is stripped, truncated, or altered. URL Encoder Online runs entirely in your browser so your data is never uploaded.

Can I encode files (not just text) with URL Encoder Online?

The Base64 tools in the PromptSpace suite support both text and file input (images, PDFs, spreadsheets) — you'll see a file picker where applicable. Other encoders (URL, HTML, hex, binary) operate on text only, since that's what those formats target.

Is URL Encoder Online safe for sensitive data like JWTs or API keys?

Yes. All processing happens in your browser — URL Encoder Online never sends your input to any server. That said, remember Base64 and hex are not encryption; if you paste a JWT here to decode it, the token content becomes visible. Just don't paste it into someone else's site.
