Generate an MD5 hash
Calculate any text's MD5 hash directly in your browser, useful for checking file integrity or compatibility with legacy systems.
Processed on your device. Nothing is sent to any server.
A hash is a one-way function: it turns any input into a fixed-length output, and it cannot be reversed to get the original text. A hash is NOT the same as encryption.
Use cases
- Checking a downloaded file's integrity by comparing its MD5 checksum.
- Verifying compatibility with legacy systems that use MD5.
- Generating a quick, reproducible identifier for content.
How it works
- 1
Type your text
Type or paste the text you want to hash.
- 2
Generate the hash
Click Generate hash and copy the hexadecimal result.
Technical details
- Example: the MD5 of "hello" is 5d41402abc4b2a76b9719d911017c592. The result is always 32 lowercase hex characters.
- Text is processed as UTF-8, and any difference changes the hash completely, including a trailing space or line break.
- It hashes text, not files: to verify a download's MD5 checksum you need a tool that reads the file itself.
Frequently asked questions
Is it safe to use MD5 for passwords?
No. MD5 is considered cryptographically broken for security use (it's vulnerable to collisions) and should never be used to store passwords; use bcrypt or Argon2 instead.
