HashtagFile helps you prove a file hasn’t been modified. Generate a tamper-evident verification certificate based on a unique SHA-256 hash, and share a public verification link so anyone can confirm the file is still the same (byte-for-byte) without creating an account. Built for people who need certainty, not cryptography jargon, designers, freelancers, legal teams, creators, and anyone sharing important files.
