MD5 Hash Generator — Free SHA256, SHA1, SHA512 & File Checksum Tool

MD5 Hash Generator — Free SHA256, SHA1, SHA512 & File Checksum Tool. Free online MD5 hash generator and SHA256 calculator. Hash text or files with MD5, SHA1, SHA256, SHA384, SHA512, Keccak and RIPEMD-160, then verify any checksum — 100% in your browser.

Our free online MD5 hash generator turns any text into its MD5, SHA1, SHA224, SHA256, SHA384, SHA512, Keccak and RIPEMD-160 digests at the same time, updating live as you type.

Instead of visiting a separate SHA256 generator, SHA1 generator and MD5 page, you get every algorithm side by side with its bit length, so you can copy the one you need or copy all of them as a report.

Switch the output between hexadecimal (lower- or upper-case), Base64, Base64url and binary — handy when an API, a config file or a database column expects one specific format.

The character and UTF-8 byte counter under the input shows exactly what is being hashed, which is the most common reason two tools disagree on a hash. Need an MD5 checksum or SHA256 hash of a file?

Switch to *File* mode and drop in an ISO, installer, archive or document: the bytes are read locally and hashed without being uploaded, so you can compare the result with the checksum published on a download page.

Paste that expected value into the hash comparison box and the tool tells you which algorithm matches — it ignores case, spaces and a 0x prefix for hex values.

MD5 and SHA1 are fine for checksums and deduplication but are broken for security; use SHA-256 or SHA-512 for integrity, a keyed HMAC Generator to sign messages, and a slow algorithm such as Bcrypt to store passwords.

This online hash calculator runs entirely in your browser with the open-source crypto-js library: your passwords, API keys and files never leave your device, and the page keeps working offline once loaded.

Note that the "SHA3" row uses the original Keccak padding (512-bit) and the Keccak-256 row matches Ethereum's keccak256, which differ from the final NIST SHA3 standard.

Frequently asked questions

How do I generate an MD5 or SHA256 hash of text?

Keep Input on Text and type or paste your text. MD5, SHA1, SHA256, SHA224, SHA512, SHA384, SHA3, Keccak-256 and RIPEMD160 hashes appear at once and update as you type. Click the copy icon next to a row, or Copy all hashes to copy every result as a list.

How do I check a file's MD5 or SHA256 checksum?

Switch Input to File and drop the file or click to select it; it is read and hashed locally without being uploaded. Paste the checksum from the download page into Expected hash (optional) and the matching algorithm is marked Match. Hex comparison ignores case, spaces and a 0x prefix.

Which output encodings can I choose?

Output encoding offers Hexadecimal (the default), Base64, Base64url and Binary. Uppercase hex only applies to hexadecimal output because Base64 is case-sensitive. Copy link creates a shareable URL that restores your text and settings.

Can I use MD5 or SHA-1 to hash passwords?

No. MD5 and SHA-1 are fast and have known collision attacks, so they are only suitable for checksums and deduplication. Even SHA-256 is too fast for password storage; use a slow, salted algorithm such as bcrypt, available in the Bcrypt tool.

Is the SHA3 row the same as the NIST SHA3-512 standard?

No. The row labelled SHA3 is Keccak-512 with the original Keccak padding, as produced by crypto-js, so its output differs from the final NIST SHA3-512 standard. The Keccak-256 row matches the keccak256 hash used by Ethereum.

Why does my hash differ from another tool's result?

A hash changes with every byte, so check for a trailing space or newline, different line endings or a different text encoding. Text is hashed as UTF-8, and the counter under the input shows the number of characters and UTF-8 bytes actually hashed.

How to use this online tool

MD5 Hash Generator — Free SHA256, SHA1, SHA512 & File Checksum Tool is designed for fast browser workflows when you need to format, validate, convert, decode, encode, generate, or inspect data without opening a heavy desktop app. Start with the input field or visible options, review the result, then copy or download the output for the next step.

Private processing in your browser

MD5 Hash Generator — Free SHA256, SHA1, SHA512 & File Checksum Tool keeps the normal processing step local in your browser. That is useful for code snippets, tokens, documents, configuration values, text samples, and other material that should not be sent to a remote service unless you explicitly choose to share it.

When this tool is useful

Use MD5 Hash Generator — Free SHA256, SHA1, SHA512 & File Checksum Tool for repeatable developer tasks, technical documentation, QA checks, quick conversions, debugging, content cleanup, and internal team workflows. The page focuses on clear inputs, immediate feedback, and output that is easy to reuse in code, reports, tickets, emails, or notes.

Practical tips

Before copying the final result, check important details such as spacing, casing, filenames, encoding, token structure, line breaks, or output format. Small checks prevent mistakes when the result is reused in source code, API requests, documentation, spreadsheets, or shared files.
