File Hash (All Algorithms): Hash Files with 22 Algorithms
File Hash (All Algorithms) calculates hashes for a selected file with 22 algorithms in one run, from MD5 to BLAKE3. It streams the file in 4 MB chunks in a dedicated web worker, keeping the interface responsive while live progress updates. Turn algorithms on or off, copy individual digests, or export all results as JSON. File data stays on your device.
File Hash (All Algorithms) is a browser-based file hashing tool that calculates digests for a file with 22 algorithms in one run, from MD5 to BLAKE3. It is useful when you need to produce file hashes, inspect the results of several algorithms, or create a local record of a file’s digests.
The tool streams the file in 4 MB chunks inside a dedicated web worker, while showing live progress. You can toggle algorithms on or off, copy each digest, or export all of the results as JSON. Processing the file in chunks and using a web worker helps keep the interface responsive while hashing takes place.
A file is the input to the hashing process, and the output is a digest for each selected algorithm. A digest is not a copy of the original file; it is a value produced by applying a hash algorithm to the file’s contents. JSON provides a convenient structured format for exporting the results, while the individual digests can be copied when you only need specific values.
File Hash (All Algorithms) runs entirely in your browser: the file is read and hashed locally, and nothing is uploaded, stored, or sent to a server. It works offline once the page has loaded, so you can continue using it without a connection. Developers and DevOps engineers can use it to inspect files, prepare hash records, verify values manually, or learn how different algorithms produce digests.
Step 1: Select the file you want to hash. The tool reads and processes the file locally in your browser.
Step 2: Choose which algorithms to run by toggling them on or off. You can calculate hashes with all 22 algorithms or select only the ones you need.
Step 3: Watch the live progress as the file is streamed in 4 MB chunks. Processing runs in a dedicated web worker so the interface does not block.
Step 4: Copy an individual digest when you need one result. To keep the complete set of results, export the digests as JSON.
Use case: Check a downloaded file against a hash value supplied by its publisher. Generate the digest with the relevant algorithm, then compare the values.
Use case: Review build artifacts before sharing or releasing them. Generate hashes locally so you can record the results alongside the files.
Use case: Calculate several hashes for one file without running separate tools. Toggle the algorithms you need and collect the results together.
Use case: Explore how different hash algorithms process the same known file. Comparing the resulting digests can support learning and testing.
Use case: Create a JSON record of a file’s digests for documentation or later reference. Exporting the results keeps the full set together.
Use case: Hash a file that you prefer not to upload to a third-party service. The file is read and processed in your browser, and nothing is sent to a server.
