How to use Convert WTF8 to UTF8
- 1. Paste the WTF-8 hex bytes. Enter the hex byte values from your WTF-8 source, such as 41 for the letter A, into the input pane.
- 2. Let the tool decode the sequence. There are no settings here; the tool decodes the bytes as standard UTF-8, since WTF-8 is byte-identical for any valid input and only diverges for lone surrogate values.
- 3. Copy the decoded text. The output pane shows the resulting characters. Copy them into your editor once you have confirmed the string decoded as expected.
When to use Convert WTF8 to UTF8
Convert WTF8 to UTF8 decodes byte sequences from the WTF-8 encoding some systems use internally to hold strings that may include lone surrogate code units, such as Windows file paths. For ordinary valid text the two encodings decode identically.
- Recovering a filename from a Rust OsString dump. A Rust program logs the raw bytes behind a Windows OsString value for debugging, and it is formatted as WTF-8. Decoding it here recovers the readable filename.
- Debugging an interop layer that passes WTF-8 strings. A cross-platform tool passes internal string buffers between components using WTF-8, and you want to confirm what text a specific buffer actually contains during debugging.
- Verifying encoding equivalence for a test suite. You are writing tests for a library that claims WTF-8 and UTF-8 decode identically for valid input, and want to confirm the claim against a range of sample strings.

Frequently asked questions
Does Convert WTF8 to UTF8 cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
