How it works
Upload your file
We instantly create a unique digital fingerprint (SHA-256 hash).
Receive your certificate
A timestamped proof confirms the file existed at this exact moment.
Verify anytime
Anyone can re-upload the same file later to confirm authenticity and that it is unchanged.
Capture & Verify instantly
You can take a photo directly with your camera and create a verifiable, unchangeable proof within seconds. Perfect for documenting contracts, handovers, damages, receipts, or anything that needs to be protected.
You can optionally share the verified file and certificate via email or messenger. Shared files are stored temporarily (24 hours).
Your file is never stored or transmitted except when you choose to share it. In that case, a secure 24-hour download link is generated for delivery.
Use hashtagfile.com to prove that your files are real, unchanged, and verifiable.
