Drop an image on this page and it instantly computes the four standard cryptographic hashes of the file: MD5, SHA-1, SHA-256 and SHA-512. The values are calculated from the raw bytes of the file - exactly what command line tools like md5sum, sha256sum or certutil would print - so they match what any other software reports for the same file. Every hash copies itself with one click, and the Copy all button grabs the full set with the file name for documentation.
If someone sent you a checksum along with an image, paste it into the verify field and the tool tells you immediately whether it matches this file - and which algorithm it is. That is the fastest way to confirm a download arrived intact, that a photo was not swapped or edited in transit, or that two files really are byte-for-byte identical. A single changed byte anywhere in the file produces a completely different hash, which is exactly what makes checksums useful for integrity checks.
MD5 produces a 128-bit hash and is fast but no longer collision-resistant; it remains fine for duplicate detection and casual integrity checks. SHA-1 gives 160 bits and sits in the same boat. SHA-256 and SHA-512, from the SHA-2 family, are the current standard for security-sensitive work - digital signatures, evidence handling, software distribution. If you are choosing one for a new workflow, use SHA-256; if you are matching a value someone else produced, this page shows all four at once so you do not have to guess the algorithm.
Hashes act as fingerprints for files. Photographers and agencies use them to prove a delivered image is the untouched original. Developers pin image assets by checksum in build pipelines. Moderation and forensics teams match known files by hash without looking at the content. Archivists detect silent corruption by re-hashing files and comparing against stored values. And anyone with a large photo library can spot exact duplicates: identical files always share identical hashes, no matter their file names. Note that re-saving or re-exporting an image writes new bytes, so even a visually identical copy gets a different hash - to read a photo's dimensions and size instead, use the Image Size Finder.
Hashing happens entirely inside your browser: the file is read locally, the checksums are computed on your device, and nothing is uploaded to any server. That makes this tool safe for confidential documents, unpublished work and personal photos alike. Once the page is open it even works offline.
Open the image on this page and the MD5, SHA-1, SHA-256 and SHA-512 hashes appear within a moment, computed from the file's exact bytes. Click any value to copy it, or use Copy all to grab the four hashes together with the file name.
It is a fixed-length fingerprint calculated from the file's data. The same file always produces the same hash, and any change to the file - even one byte - produces a completely different one. That makes hashes a reliable way to identify files, verify downloads and detect tampering or corruption.
Paste the expected checksum into the verify field under the results. The tool compares it against all four computed hashes and tells you whether it matches and which algorithm produced it, so you do not need to know in advance whether you were given an MD5 or a SHA-256.
Because the bytes changed. Editing, re-saving, converting, compressing or even re-exporting an image with identical pixels writes a new file with different bytes, and therefore a different hash. Renaming a file, on the other hand, does not touch its content - the hash stays the same.
For security-relevant purposes - signatures, evidence, software releases - use SHA-256 (or SHA-512). MD5 and SHA-1 are considered cryptographically broken for collision resistance, but they remain acceptable for finding duplicates or quick integrity checks, and plenty of existing systems still publish MD5 checksums.
No. The file is read and hashed entirely inside your browser using the built-in WebCrypto engine; nothing is transmitted to any server, so the tool is safe for private and confidential files.
