MD5 Hash Generator
100% PrivateSecurity & Privacy UtilitiesCompute the MD5 checksum of text or a file, entirely in your browser.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
MD5 is broken for security use: collisions can be forged cheaply, so never use it for passwords, signatures or proving a file is safe against tampering. It is fine for quick checksums against accidental corruption and for legacy systems.
- 1Choose Text or File.
- 2Type the text, or pick the file; files are read locally and never uploaded.
- 3Press Compute MD5.
- 4Copy the 32-character hex hash and compare it wherever you need to.
The MD5 of the text abc is 900150983cd24fb0d6963f7d28e17f72, one of the published MD5 test suite values. The MD5 of an empty input is d41d8cd98f00b204e9800998ecf8427e.
- MD5 is not safe for security purposes: forged collisions are practical, so a matching MD5 does not prove a file is untampered. Use SHA-256 for integrity that matters.
- Text is hashed as UTF-8 bytes, the same bytes most tools use; a trailing newline is part of the input and changes the result.
- There is no file size limit in the tool itself, but very large files are read into memory, so a multi-gigabyte file can strain a small device.
- MD5 says nothing about who made a file, only about its exact bytes.
Speed and history. It is fine for detecting accidental damage in downloads and backups, and many older catalogues only publish MD5 values.
About this tool
The MD5 Hash Generator computes the MD5 checksum of text or a file, entirely in your browser. MD5 survives today as a quick fingerprint for spotting accidental corruption and for compatibility with older systems that still publish MD5 checksums.
