What is MD5 Hash?
MD5 Hash turns any text into its 128-bit MD5 digest, shown as a 32-character hexadecimal string. It is fast and widely supported, which makes it handy for checksums, cache keys, and comparing files or strings for changes. Note that MD5 is considered broken for security use — do not rely on it for passwords or signatures — but it remains fine for non-adversarial integrity checks. Everything runs in your browser, so your text is never uploaded.
How to use MD5 Hash
Enter your text
Type or paste anything into the Text box, or click Load file to hash a .txt, .json, .csv, or other text file. The MD5 hash recomputes live as you edit.
Read the digest
The MD5 hash appears on the right as 32 lowercase hexadecimal characters. The same input always produces the same hash, and any change to the input changes the whole digest.
Choose the case
Toggle Uppercase hex if the tool or database you are comparing against stores MD5 hashes in capitals. It is the same digest with only the A-F letters cased differently.
Copy or download
Use Copy to grab the hash, or Download to save it as a text file so you can paste it into a checksum manifest, ETag, or verification script.
Common uses
- Verify a file matches a published MD5 checksum
- Generate cache keys or ETags from strings or file contents
- Detect whether text or config changed between two versions
- De-duplicate records by hashing their contents
- Reproduce MD5 test vectors while building or debugging software
- Create short, stable identifiers for legacy systems that expect MD5
