Client-side integrity check

Image hash generator for evidence and integrity checks

Generate SHA-256, SHA-512, SHA-384, or legacy SHA-1 hashes for images and screenshots directly in your browser. Files stay on your device — no uploads, no account, no server-side storage.

Why hash images?

A hash is a fingerprint for a file. If the file changes, the hash changes too. That makes hashes useful for evidence notes, incident reports, file integrity checks, and before/after documentation.

For most workflows, use SHA-256. Use SHA-1 only when you need to compare against an older system that still reports SHA-1.

Privacy toolkit

Working with sensitive screenshots or photos?

Use PixBatch Privacy Tools to redact visible details, remove hidden metadata, and create hashes for evidence notes — all locally in your browser with no uploads.

RedactMetadataHash

Choose files and algorithm

Select one or multiple image files. Hashing happens locally with your browser's Web Crypto API.

PixBatch calculates hashes in your browser. Your files are not uploaded to PixBatch servers.

Hash results

Copy hashes into tickets, reports, or integrity logs.

No files hashed yet

Choose images on the left to generate hash values. Results will appear here without uploading files.

Evidence notes

Record a screenshot hash before and after redaction to document exactly which file was reviewed or shared.

Privacy workflow

Pair hashing with the screenshot redactor and EXIF remover when preparing images for tickets or reports.

Local processing

Hashes are generated locally by your browser, so the original files do not need to leave your device.
