URL encoding (percent-encoding) escapes characters that would otherwise break a URL — spaces, ampersands, quotes, non-ASCII characters. This tool encodes and decodes any string, with a separate mode for full URLs (which preserves the / and : characters) and for component-level encoding inside query parameters. Use it whenever you are debugging redirects, constructing API calls, or building deep links into apps.
Load the page — URL Encoder is ready to use immediately, no login and no configuration required.
Enter, paste, or upload the data that URL Encoder needs — the input area at the top guides you with a placeholder example.
Trigger the action; the result appears in the output panel within a second or two.
Use the copy or download button to grab the output for your workflow — nothing is stored on our servers.
URL Encoder is built for people who want a fast, honest answer without wading through ads, sign-up walls, or feature bloat. Load the page, use the tool, get on with your day. Toolzer's design philosophy is simple: privacy-first (no tracking, no accounts), performance-first (the page is interactive in under a second on a 3G connection), and honesty-first (no fake ratings, no dark patterns, no upsells). URL Encoder follows the same rules as every other utility on the site. You can bookmark this page, share the URL with a colleague, or pin it to your browser's toolbar — the experience will be identical every visit, and it will keep working even if you're on airplane Wi-Fi. Real people use this tool for real work — freelancers cleaning up client deliverables, sysadmins triaging tickets, students finishing assignments — and it is tuned for those workflows, not for demo videos.
Any time user data ends up in a URL — query parameters, path segments, redirect targets, OAuth callbacks.
encodeURI leaves reserved URL characters alone. encodeURIComponent encodes them — use it for individual query values.
In URL paths, + is literal. In query strings, + is an alias for space. Encoding to %20 works everywhere unambiguously.
Yes. Non-ASCII characters are first encoded as UTF-8 bytes, then percent-encoded — the standard browser behaviour.
