How it works
Three steps. No upload, no signup.
- 1
Drop your file
Click the dropzone above or drag a Text from your desktop. Files of any size, there's no upload, so there's no upload limit.
- 2
Convert in your browser
The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.
- 3
Download
Get your URL-encoded text the moment the conversion finishes. Convert another, or close the tab.
Files stay on your device
Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.
No file size limit
Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.
Free, no signup, no ads on conversions
No account required. No watermark on the output. No queue. Drop a file, get a converted file.

About Text and URL-encoded text
URL-encoded text, Percent-encoding (RFC 3986)
URL encoding (also called percent-encoding) replaces characters that have special meaning in URLs (`?`, `&`, `=`, space, `#`) with their `%XX` hex escape. Multi-byte UTF-8 characters expand to multiple `%XX` sequences. Required for query strings, form bodies, and any URL component that contains user input. The standard is RFC 3986; JavaScript's `encodeURIComponent` is the most common implementation.
How to open
Any text editor displays URL-encoded strings. Browser DevTools shows decoded forms in the Network tab's request inspector. Online decoders abound; most languages have a native function (`urllib.parse.unquote` in Python, `decodeURIComponent` in JS).

FAQ
Common questions
Is this Text → URL-encoded converter really free?
Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.
Where does my file go when I convert it?
Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.
What's the maximum file size?
Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.
Why convert Text to URL-encoded text?
Universal text interchange. Safely passing arbitrary text through URL query strings and form bodies. The most common reason to convert is compatibility, URL-encoded text works in places where Text doesn't, or vice versa.
How do I open a Text file in the first place?
Every text editor on every platform. Browser previews.
Does this work offline?
Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.
Can I convert multiple files at once?
Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
