Prove when a document existed — permanently.
Free to use. No account required. Create a free document timestamp and get proof of existence for your documents in under 30 seconds.
🔒 Your file never leaves your device. Only a secure fingerprint (hash) is sent to create the proof.
Why notarizing only the last page may leave other pages unprotected.
Popular Use Case
Passport Photos
U.S. passport photos must be taken within the last 6 months. If questioned, how would you prove the creation date? Generate a compliant U.S. passport photo at Kindro and anchor it to Bitcoin with EverCert.
What you receive — at no cost
- ✓A proof package for your records
- ✓A timestamp certificate for records or sharing
- ✓A secure fingerprint of your document
Please retain a copy of your certificate and proof files with your document records.
How EverCert works
A full walkthrough showing how to create, anchor, and independently verify a document proof.
Watch a 5-minute walkthrough
How it works
- 1You upload a file
- 2A proof receipt is created and later anchored to Bitcoin
- 3You can check it anytime. Once anchored to Bitcoin, it can be independently verified.
Why use Bitcoin for timestamps?
- •Tamper-proof: Once anchored, records cannot be changed
- •Decentralized: Does not rely on a single company or server
- •Long-term verifiable: Can be independently verified years later using public blockchain data
Can I verify without EverCert?
Yes. Your downloaded proof package works independently. Even if EverCert is unavailable in the future, you can still verify using public tools (such as OpenTimestamps / open-source verifiers). See the step-by-step verification guide →

Frequently Asked Questions
Is EverCert free to use?
Yes. EverCert is free to use and does not require an account. You can create and verify proofs at no cost.
Do you upload my document when creating a proof?
No. Your file never leaves your device. Only a secure fingerprint is sent to create the document proof.
Is the proof permanent?
Yes. Once created, your proof cannot be changed. After it is anchored to Bitcoin, it becomes a permanent, independently verifiable record.
Can I verify a proof without EverCert?
Yes. Your proof works independently. You can verify it yourself using free, open-source tools.
Why does verification sometimes say "pending"?
Proofs are created immediately and later anchored to Bitcoin. Until that happens, the timestamp proof is valid, but verification will show as pending.
