MD5 Hash Generator
Generate the MD5 hash digest of any text or file, instantly inside your browser.
What is MD5?
MD5 is a widely used hashing algorithm that takes any input — text or a file — and produces a fixed-length, 128-bit (32 hexadecimal character) digest. The same input always produces the same hash, and even a tiny change to the input produces a completely different result, which makes MD5 useful for quickly comparing files or strings for equality. MD5 is not cryptographically secure and should never be used for passwords or security-sensitive purposes — it's best suited for checksums, deduplication, and cache keys.
This tool hashes typed text or an uploaded file directly using MD5, entirely inside your browser.
GuideHow to use it
How the hash is calculated
The input is read as raw bytes — either the UTF-8 bytes of typed text, or the exact bytes of an uploaded file — and processed through the selected algorithm entirely in JavaScript, producing a 128-bit digest displayed as 32 hexadecimal characters.
Why it helpsFeatures & benefits
Why this runs entirely in your browser
Files and text hashed here can contain private data, so nothing is uploaded to a server. The algorithm runs entirely in JavaScript locally in the tab, which means it keeps working offline once the page has loaded.
Common uses
Verifying a downloaded file matches its published checksum, quickly comparing two files for equality without opening them, generating a stable cache key from a string, or working through a computer science exercise on legacy hashing algorithms.
Frequently asked questions
A few things people usually want to know before trusting the numbers.
No. MD5 is considered cryptographically broken — collisions can be deliberately engineered. It should never be used for passwords, signatures, or anything security-sensitive. Use it for checksums and non-adversarial deduplication only.
128 bits, shown as 32 hexadecimal characters.
Yes. Switch to File mode and upload or drag a file — its exact bytes are hashed, not just its text content.
Yes. Clicking a different algorithm switches the page while keeping the text or file you've already entered.
No. All hashing happens locally in your browser. Nothing typed, pasted, or uploaded here is sent to a server, stored, or shared.
