MD5 Generator
Calculate MD5 for exact text or file bytes
Enter text and click Generate Hashes, or drop a file to hash its bytes; collision risks and usage limits are available in Advanced mode.
The full guide also includes pitfalls, worked examples, snippets, FAQs, and related tools for checking results or troubleshooting.
About this tool
Use MD5 when a legacy workflow explicitly requires its 128-bit digest, displayed here as 32 hexadecimal characters. Text is encoded as UTF-8 without trimming; a dropped file is hashed as bytes. Basic mode also shows SHA-1 and SHA-256, while Advanced adds SHA-512. Empty text is a valid input. MD5 collisions are practical, so a matching value is not proof of authenticity. Password storage requires a dedicated password hash such as Argon2id, bcrypt, or scrypt with suitable parameters.

A matching MD5 does not prove authenticity.Frequently Asked Questions
Is a digest a unique fingerprint?
No. MD5 always returns 128 bits, so different inputs can collide. Use it only where legacy or accidental-corruption checks permit that limitation.
Why do spaces and line endings matter?
Hashing uses bytes. A trailing space, UTF-8 encoding change, BOM, LF, or CRLF can change the digest. A pasted textarea is not a guarantee of the original file bytes.
How should I compare a published file checksum?
Drop the original file and compare the full digest with a checksum from a trusted source. Do not decode binary files as text first.
Is the output 16 or 32 characters?
This tool emits the full 32-character hexadecimal MD5 digest. It does not provide the shortened middle-16-character convention used by some legacy systems.
Can MD5 or plain SHA-256 store passwords safely?
Neither is an appropriate standalone password-storage scheme. Use a salted password hash with a configurable work cost, such as Argon2id, bcrypt, or scrypt.
