MD5 checksums, quickly
MD5 produces a 32-character fingerprint that's still widely used for file checksums, cache keys, ETags and legacy systems. Type text or choose a file to get its MD5 instantly, with SHA-1, SHA-256, SHA-384 and SHA-512 shown underneath in case you need a stronger algorithm.
Paste the checksum from a download page into the compare box to verify the file, choose hex or Base64 output (Base64 is what the Content-MD5 header and many cloud storage APIs use), or turn on HMAC-MD5 for legacy signature schemes.
How to get an MD5 hash
- 1
Enter text or pick a file
Everything stays on your device.
- 2
Read the MD5 hash
Shown at the top of the list.
- 3
Compare or copy
Verify a checksum or copy the value.
Key features
Text and files
Hash files up to 512 MB.
Stronger hashes too
SHA-1, SHA-256, SHA-384 and SHA-512.
Base64 output
For Content-MD5 headers and storage APIs.
HMAC-MD5
For older APIs that still need it.
Common uses
- Checking downloads: Match a file against an MD5 listed by the publisher.
- Deduplication: Spot identical files by comparing hashes.
- Cloud storage: Compute Content-MD5 for uploads.
Tips and good to know
- MD5 is broken for security: attackers can create two files with the same MD5. For anything security-related, use the SHA-256 Hash Generator.
- Never store passwords as MD5; use the bcrypt Password Hash Generator.
Frequently asked questions
Is MD5 still safe to use?
For checking accidental corruption and cache keys, yes. For security — signatures, certificates, passwords — no, because collisions can be created deliberately.
Can MD5 be decrypted?
No. MD5 is a one-way hash. “MD5 decrypt” sites only look up common inputs in huge precomputed tables.
Why is my MD5 different from another tool's?
Usually an extra space or line break, or different text encoding. This tool hashes your text exactly as typed, in UTF-8.
