How to use
- Type or paste your text into the input box, or drop a file into the dropzone.
- The tool instantly computes the MD5, SHA-1, SHA-256 and SHA-512 hashes.
- Review the hex digests shown in a row for each algorithm.
- Click Copy next to any hash to copy the checksum to your clipboard.
Frequently asked questions
Which hash algorithms are supported?
The generator produces four hashes at once: MD5, SHA-1, SHA-256 and SHA-512. SHA variants use the browser's native crypto.subtle for speed, and MD5 is computed with a small built-in implementation.
Are my text or files uploaded to a server?
No. Every hash is calculated 100% in your browser using JavaScript. Your text and files stay on your device and nothing is ever uploaded, so it's safe for sensitive or confidential data.
Can I hash a file as well as text?
Yes. You can type or paste text into the box, or drop a single file into the dropzone. The file is read locally and its MD5, SHA-1, SHA-256 and SHA-512 checksums are shown along with its name and size.
Is there a file size limit?
There is no fixed limit, but very large files depend on your device's memory since the whole file is read into the browser to compute the hash. Multi-GB files may be slow or fail on low-memory devices.
Which hash should I use for verifying downloads?
SHA-256 is the most common choice for verifying file integrity today. MD5 and SHA-1 are still widely used for checksums but are considered weak for security-critical purposes.
Does hashing the same input always give the same result?
Yes. Hashing is deterministic, so identical input always produces the identical hex digest. Even a one-character change to the text or a single byte in the file changes the resulting hash completely.
About this tool
Generate MD5, SHA-1, SHA-256 and SHA-512 hashes from text or a file. Runs entirely in your browser, so your data stays private and is never uploaded.
