Practical ways to use this tool

Technical work

URL parameters

Encode an individual value before adding it to a URL.

Documentation

Technical examples

Represent spaces and reserved characters as percent escapes.

Data preparation

Round-trip checks

Compare a known component with its decoded version.

Features and how to use them

Encode one component at a time

Spaces and reserved characters are escaped.

How this transformation works

This tool applies component encoding to the entire input. A space becomes %20 and characters such as ampersands, slashes and question marks are encoded when required. Use it for a parameter value or path component before assembling a URL.

See a small example

A short input makes the transformation easier to inspect.

View input, options and result

This example was checked with the current tool. The options shown apply only to this example; your editor keeps the settings you select.

Input: hello world & more
Result: hello%20world%20%26%20more

No options are required.

Start with your own text

Upload a text file, write directly, or try the sample.

Opening and applying the tool

The entry screen accepts one UTF-8 TXT, CSV, JSON, XML, HTML or HTM file and opens the editor. Imports are text content, not a PDF or Word conversion. Review the source and choose URL Encode when ready. Editing or importing alone does not apply the transformation.

Review, save or continue

Check the report before saving or continuing with the text.

Using the finished text

Inspect the percent-encoded component in the monospaced result and compare input and result UTF-8 byte sizes in Result overview. Percent-encoded output can be larger than the source, especially for non-ASCII characters. Open Show spaces and tabs to reveal spaces as ·, tabs as ⇥ and line endings as ↵. These marks are only a preview; copied and downloaded text keeps its actual whitespace. Copy the reviewed text or use the download icon to save UTF-8 TXT. Editing the result hides the calculated details until you run the tool again. Continue to offers compatible next tools for the current text and their limits. Review the transferred text before running the next operation.

Files, limits and privacy

Input: Pasted text or one UTF-8 TXT, CSV, JSON, XML, HTML or HTM file
Output: Editable text and UTF-8 TXT

Maximum input and result: 1 MB of UTF-8 text, with a 1,048,576-character input ceiling. Expanding transformations must also fit the result limit. The whitespace preview shows at most 12,000 Unicode code points. This preview limit does not shorten the editable result or its TXT download.

This text operation runs in your browser; its source and result are not sent for conversion. A draft may be kept in this browser tab when session storage is available. Clear removes the current draft; download important work before closing the tab.

See the Privacy Policy for file and data handling.

FAQ

Good to know

Does URL Encode send my text to a server?

No. This tool processes text in your browser. Text-file imports and downloads stay on your device.

Can I edit and download the result?

Yes. The result remains editable. Copy it or download a UTF-8 .txt file from the result page.

How much text can I process?

Text input and generated output are limited to 1 MB to keep your browser responsive. Split larger documents into smaller parts.
