File Hash Generator guide
Hash pages are useful when the search intent is tied to a specific digest algorithm, checksum workflow, or file-integrity task.
Common uses
- Verify downloaded installers, archives, images, PDFs, or spreadsheets.
- Check that a file did not change during transfer.
- Compare two file copies without uploading them.
Text versus file input
Text hashes are best for strings, copied values, payload examples, and developer checks. File hashes are best for downloads, archives, images, spreadsheets, and documents that need an integrity fingerprint.
Security guidance
File hashes can prove that two files are byte-for-byte identical, but they do not prove the file is safe or trustworthy unless the checksum source is trusted.
Comparison checklist
- Compare the full digest, not just the first or last few characters.
- Make sure both sides use the same algorithm and output format.
- Regenerate the hash after any edit, compression, re-export, or file transfer.
Frequently asked questions
Are files uploaded to generate the hash?
No. File hashing runs locally in your browser, so the selected file is not uploaded to PlanetToolbox.
Which file hash algorithm should I use?
Use the algorithm published by the source you are comparing against. If you are choosing a modern default, SHA-256 is a practical choice.
Can a file hash change after renaming a file?
Renaming a file does not change its content hash, but editing, compressing, re-exporting, or converting the file will change the hash.
