Overview

About this tool

A clear look at what this tool is for and why people use it.

URL Encoder

Encode text for use in URLs and query strings. Default mode follows RFC 3986 (rawurlencode). Switch to form encoding when you need spaces as plus signs (+) like application/x-www-form-urlencoded.

Copy the encoded string with one click. Free and private.

Under the hood

How it works

Follow the path from input to output — transparent and easy to scan.

• RFC 3986 mode

• RFC 3986 mode uses rawurlencode (spaces become %20).

Calculation

• Form mode uses urlencode (spaces become +).

Result

• Reserved characters are percent-encoded for safe transport.

Pro tips

Tips

Small habits that make this tool even more useful day to day.

Get accurate results

Double-check units and inputs before you rely on URL Encoder output for anything important.

Work faster

Use the examples below as a starting point, then tweak values to match your scenario.

On any device

This tool is mobile-friendly — bookmark the page so you can reopen it in one tap.

Watch out

Common mistakes

Avoid these slip-ups so your result is ready the first time.

Leaving required fields blank

Enter every value the workspace asks for before calculating — empty fields usually block a result.

Using invalid numbers

Avoid negative values or percentages outside a valid range unless the tool explicitly allows them.

Mixing up units

Keep units consistent (currency, length, weight, time) so the formula returns a meaningful answer.

FAQ

Frequently asked questions

Straight answers to the questions people ask most.

Use form mode for classic query-string body encoding where spaces are +. Prefer raw for path segments and modern encodeURIComponent-style needs.
RFC 3986 (raw) is the closest common PHP equivalent for component encoding.
You can paste any text. Encoding an entire URL will also encode :, /, and ?, which is usually only ideal for query values.
Yes.
