hashtagfile.com – Verify file integrity without uploading

Summary: HashtagFile generates a tamper-evident verification certificate using a unique SHA-256 hash, enabling anyone to confirm a file remains unchanged without uploading it or creating an account.

What it does

It creates a public verification link based on the file’s SHA-256 hash, allowing byte-for-byte comparison without sharing the actual file.

Who it's for

Designed for designers, freelancers, legal teams, creators, and others needing simple file integrity verification without cryptographic complexity.

Why it matters

It solves the challenge of proving a file hasn’t been altered after leaving your device, addressing risks from near-identical file modifications.
