Hash Generator
Generate MD5, SHA-1, SHA-256 and SHA-512 hashes from text or files. Runs entirely in your browser — nothing is ever uploaded.
How to Generate a Hash Online
ToolsPix Hash Generator converts any text or file into MD5, SHA-1, SHA-256, or SHA-512 hashes directly in your browser using the native SubtleCrypto API. There is no software to install, no account to create, and no data is sent to any server.
Why use ToolsPix Hash Generator?
- Completely free with no input-size limits other than your device memory.
- SHA-1, SHA-256, and SHA-512 are computed with the browser's native
SubtleCryptoAPI — your text and files never leave your device. - Works on Windows, Mac, Linux, iPhone, and Android — anywhere with a modern browser.
- Hash text instantly or drop a file to generate its fingerprint for integrity verification.
- No watermarks, no sign-up, and no third-party trackers.
Steps to generate a hash
Enter your text in the input field or drag and drop a file onto the tool, then select the algorithm — MD5, SHA-1, SHA-256, or SHA-512 — from the dropdown. The hash is generated instantly and appears below ready to copy. Once the page is loaded, the tool also works completely offline.
Frequently Asked Questions
Is hash generation reversible?
No. Cryptographic hash functions are one-way — there is no algorithm to reverse a hash back to the original input. An attacker who obtains a hash cannot recover the original data without brute-forcing every possible input.
Are my files uploaded to a server?
No. All hashing happens inside your browser using the Web Crypto API for the SHA family and a native JavaScript MD5 implementation. Your text and files never leave your device.
What is the difference between MD5 and SHA-256?
MD5 produces a 128-bit (32-character) hash and is very fast, but is cryptographically broken. SHA-256 produces a 256-bit (64-character) hash and is significantly more collision-resistant — recommended for any security-sensitive use such as file verification or digital signatures.
Can two different inputs produce the same hash?
In theory yes — this is called a collision. In practice, SHA-256 and SHA-512 are designed so that finding a collision is computationally infeasible with current hardware. MD5 and SHA-1 have known collision vulnerabilities, which is why they should not be used for security purposes.
When should I use SHA-512 instead of SHA-256?
SHA-512 provides a larger output (128 hex characters vs 64) and a higher security margin, making it preferable for high-security applications such as password hashing, digital certificate chains, and government or compliance-level integrity verification. For everyday file verification, SHA-256 is sufficient.
