Why Convert Text to URL-encoded?

Spaces, ampersands, question marks, and non-ASCII characters break URLs unless they are percent-encoded. This tool applies standard RFC 3986 encoding (via encodeURIComponent) so your text is safe to place inside a query string, path segment, or form submission.

Common use cases

  • You have a Text file and need it in URL-encoded format for building query strings with special characters.
  • The target software or platform requires URL-encoded but your file is in Text.
  • You want to reduce file size or improve compatibility without using desktop software.
Keep in mind: Encoded text is hard to read and must be decoded exactly once — double-encoding is a classic source of bugs.

About the Formats

Text (Plain Text)

Plain text is the simplest possible data format: a sequence of characters with no styling or structure. It is the universal input and output of every text tool, from encoders to case converters.

Compatibility: Universal — readable on every device and operating system ever made.

URL-encoded (Percent-Encoded Text)

URL encoding (percent-encoding) replaces characters that are not allowed in URLs with %-prefixed hexadecimal sequences — a space becomes %20, an ampersand %26. It keeps query strings, form submissions, and path segments unambiguous and safe to transmit.

Compatibility: Universal — defined by RFC 3986 and supported natively everywhere.

100% Private & Browser-Based

Your files never leave your device. All conversion happens locally in your browser — nothing is uploaded to any server. No sign-up required.

Your file is processed entirely within your browser using local JavaScript. It is never uploaded to any server. Only you can access your file.

For browser-based conversion, files up to 50 MB work best. Very large files may take longer depending on your device. We recommend splitting very large files before converting.
