MD5 Hash Generator
Generate a 128-bit MD5 hash for quick checksums and file comparison. MD5 is fast, but it is not secure against deliberate collisions, so avoid it for passwords or signatures.
Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes from any text or file. Instant, free and no signup.

HASHING GUIDE
Hash Generator – Create MD5, SHA-1 and SHA-256 Hashes Online
Need a quick, free hash generator? Create MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes from any text or file in your browser. Paste your text, or choose a file, and the hash values appear instantly. There is nothing to install, no account to create, and your data stays on your device.
SHA-256 Hash Generator
Create SHA-256 hashes for integrity checks, data verification and development work. SHA-256 is widely used and is a solid default choice for most modern needs.
File Checksum Generator
Hash a file and compare the result with the checksum published by the download source. If the values match, the file was not changed or corrupted along the way.
How to Generate a Hash Online
- Add your input: Type or paste text, or switch to the File tab and select a file.
- View the hashes: MD5, SHA-1, SHA-256, SHA-384 and SHA-512 are calculated automatically.
- Choose the output case: Show hashes in lowercase or UPPERCASE hexadecimal.
- Copy the result: Copy one hash, or use Copy all to grab every value.
MD5 vs SHA-1 vs SHA-256: Which One Should You Use?
MD5 and SHA-1 are still common for checksums and legacy systems, but both are considered broken for security purposes. SHA-256, SHA-384 and SHA-512 belong to the SHA-2 family and are the better choice when you need stronger integrity checks. Longer hashes take slightly more work to compute but offer a larger safety margin.
Is Hashing the Same as Encryption?
No. Hashing is a one-way process: the same input always gives the same hash, but you cannot turn a hash back into the original data. Encryption is two-way and can be reversed with a key. For storing passwords, use a dedicated password hashing algorithm such as bcrypt or Argon2 instead of a plain MD5 or SHA hash.
COMMON QUESTIONS
Frequently Asked Questions About Hash Generators
Answers to common questions about MD5, SHA-256, file checksums and how this hash generator works.
What is a hash generator?
A hash generator turns any text or file into a fixed-length string of characters called a hash or digest. Even a tiny change in the input produces a completely different hash, which makes hashes useful for checking data integrity.
Which hash algorithms are supported?
This tool supports MD5, SHA-1, SHA-256, SHA-384 and SHA-512. All five are calculated at the same time, so you can copy whichever one you need.
Can I generate a hash for a file?
Yes. Switch to the File tab, choose a file of up to 100 MB, and the hashes are calculated in your browser. Compare the result with the checksum provided by the file's publisher to verify the download.
Are my text and files uploaded to a server?
No. The hashes are calculated locally in your browser, so your text and files are not sent to our server.
Is MD5 safe to use?
MD5 is fine for simple checksums where nobody is trying to tamper with the data. It is not safe for passwords, digital signatures or anything security-sensitive. Use SHA-256 or stronger for those cases.
Can a hash be reversed to get the original text?
No. Hashing is a one-way function. Short or common inputs can sometimes be guessed with lookup tables, but a hash cannot be mathematically decoded.
Why does the same text give a different hash with extra spaces or line breaks?
A hash covers every character, including spaces and line breaks. Even one extra space or a different line ending creates a completely different result.
