Check this tool against our published list

Your browser downloads this checker's WebAssembly module, hashes it with itself, and compares the result with the module's entry in our release manifest.

A match shows that the module you received is byte-for-byte the one listed in the manifest this site serves.

It does not show:

• that the manifest itself is genuine (this page doesn't check its signature; you can, with our public key: see below);
• that the rest of this page or this site is unmodified;
• anything about the converter.

Because the module checks itself, an altered module could report a match. For an independent check, hash the module with another tool (for example sha256sum) and compare.
