Does Encoding Studio upload my text to any server?
No. Every tool runs in your browser, and nothing you type or paste is sent to a server.
What's the difference between URL Encoding and URI Component Encoding?
URL Encoding (encodeURI) preserves characters that are structurally meaningful in a whole URL (: / ? # & =). URI Component Encoding (encodeURIComponent) also escapes those characters, which is the right choice for a single query parameter value or form field. Using the wrong one can quietly break a URL.
Is Base64 encryption?
No. Base64 is a reversible way to write data as text, not encryption, and anyone can decode it. Don't use it to protect secrets.
