FAQ
Is MD5 reversible?
No. MD5 is a one-way hash; you can only verify by hashing the same input and comparing outputs.
Is MD5 secure for passwords?
No. MD5 is considered broken for security use; use a modern password hash (e.g., bcrypt/Argon2) instead.
What encoding is used for the input text?
This tool hashes the UTF‑8 bytes of your input (via TextEncoder).
Why does my MD5 differ from another tool?
Common causes are different encodings, hidden whitespace/newlines, or hashing a file vs. hashing its filename/text.
Can I hash files here?
This page hashes text input only. For file checksums you need a file-hash tool that reads file bytes.
Does letter case matter in the MD5 output?
No. The digest is the same; uppercase/lowercase is just formatting of the hex string.
Is the hashing done locally?
Yes. The MD5 calculation runs in your browser and does not require any network requests.
