Free Tool — Zero TTrust Media
Drop your files below. We generate a SHA-256 hash manifest with cryptographic timestamps — a legally defensible record of content ownership. Free. No account. No uploads to any server.
Images, videos, audio, documents
All processing happens in your browser.
Nothing leaves your device.
Drop your original content files — photos, videos, audio. Everything stays on your device. Nothing is uploaded.
Add your name, platform, and copyright notice so the manifest is properly attributed to you.
Download the HTML manifest. It contains SHA-256 hashes, file sizes, timestamps, and your copyright info.
Keep the manifest with your original files. If your content is stolen, this is your proof of prior creation.
