Introduction

Ever copied a link into your browser or email only to find it littered with %20, %3A, and %C3%A7 instead of normal text? If you’re a developer, marketer, or content creator, you’ve likely bumped into URL encoding issues—especially when handling query strings or sending data via GET parameters. It’s exactly the kind of small headache that leads to broken links, misunderstood form data, or frustrating unreadability.

That’s why URL encoding/decoding tools matter. They transform special characters—like ?, &, spaces, or unicode symbols—into a percent-encoded format that works universally across browsers and servers, and vice versa. Whether you’re debugging links in logs, cleaning up messy query strings, or preparing URLs for APIs, these tools save time and prevent quirks.
