Question 1

What is URL encoding and why do I need it?

Accepted Answer

URL encoding converts special characters (spaces, &, =, ?, #) into a safe format (%20, %26, etc.) so they don't break URLs. It's essential when passing values as query parameters or in request bodies.

Question 2

What is Base64 and where is it used?

Accepted Answer

Base64 encodes binary data into ASCII text format. It's used for data URLs (embedding images in HTML/CSS), email attachments, API requests, and storing binary data in JSON or text files.

Question 3

Do you store my data?

Accepted Answer

No. All encoding and decoding runs locally in your browser using JavaScript. Your data never leaves your device and we never see or store it.

Question 4

What is the difference between URL encoding and HTML encoding?

Accepted Answer

URL encoding escapes characters for use in URLs (spaces become %20). HTML encoding escapes characters for use in HTML (< becomes <). They serve different purposes.

Question 5

Can I convert Markdown to HTML?

Accepted Answer

Yes. Paste your Markdown and get instant HTML output. You can copy the HTML or download it as a complete .html file ready to use.
