Online Hash Generator for Text and Files

Generating hashes from text is useful for verifying strings, creating unique identifiers, or testing hash algorithms. Here's how to use Text mode:

1. Select the Text mode in the toolbar if it is not already active
2. Type or paste your text into the Text Input area
3. The MD5, SHA-1, SHA-256, and SHA-512 fields update automatically with the corresponding hashes
4. Click the copy button next to any hash to copy it to your clipboard

Hashes update in real-time as you type, making it easy to experiment with different inputs and see how cryptographic hash functions produce completely different outputs for even minor changes.

File hashing is commonly used to verify downloads, check file integrity, and detect tampering. To generate hashes for a file:

1. Click the File button in the toolbar to switch to File mode
2. Click Open File and choose the file you want to hash
3. Review the file name, size, and type in the file preview panel
4. The tool computes MD5, SHA-1, SHA-256, and SHA-512 hashes for the file and displays them on the left
5. Copy the hashes as needed to compare with a published checksum or another tool

This browser-based hash generator supports any file type and processes everything locally without uploading your files to a server. Large files may take slightly longer to hash depending on your device.

Compare mode lets you verify whether two files are identical by comparing their hash values across multiple algorithms:

1. Click the Compare button in the toolbar to open Compare mode
2. Select File 1 and File 2 using the file selectors on each side
3. The tool calculates MD5, SHA-1, SHA-256, and SHA-512 for both files and shows them side by side
4. Check the status indicators to see whether each pair of hashes matches
5. If all hash values match, the files are effectively identical at the byte level

This is useful for verifying that a file you downloaded matches the original, confirming backups are exact copies, or detecting any unauthorized modifications to important files.

A hash function turns any input into a fixed length string of characters called a hash. Algorithms such as MD5, SHA-1, SHA-256, and SHA-512 are commonly used to create checksums for files, verify downloads, and detect accidental corruption.

In many workflows, a publisher provides a known good hash for a file. After you download the file, you can run it through a hash generator and compare the results. If the hash you generate matches the published checksum, it is a strong indication that the file has not changed.

MD5 and SHA-1 are considered weak for security sensitive applications because they are vulnerable to collision attacks, but they are still commonly used for basic integrity checks. For stronger cryptographic guarantees, SHA-256 or SHA-512 are recommended.

This online hash generator runs client side, so your files are never uploaded. You can also use our EXIF data remover to strip metadata from photos, or view EXIF data in your images for privacy protection.

Does this hash generator upload my files?

No. All hashing happens directly in your browser using client side code, so your text and files are not uploaded to a server.

Which hash algorithms does this tool support?

The tool supports MD5, SHA-1, SHA-256, and SHA-512 for both text and files.

Can I use this tool to verify a file download?

Yes. Generate a hash for your downloaded file and compare it with the published checksum to confirm the file has not changed.

Can a hash be reversed to get the original input?

No. Cryptographic hash functions are one way and cannot be reversed to recover the original input.
