Human-readable forensic summary with all metadata
The only web evidence tool whose proofs survive even if our company disappears. Self-verifiable cryptography — no vendor lock-in, no “trust us” required.
Tamper-proof cryptographic evidence courts accept — hash, signature, blockchain timestamp, capture video, Provenance Certificate. One click. 41 seconds.
From $8.99/mo · Up to 15 files per package · 23 countries
Also available for Microsoft Edge · The only extension with legally binding EU timestamps in all 27 member states
ProofSnap is a Chrome & Edge extension that captures web pages as court-admissible evidence in 41 seconds. Three capture options — single page, multi-tab browsing session (with per-tab forensic packages), or signed video proof (Auto, Manual, or Session-wide screen recording). Every capture includes a SHA-256 cryptographic hash, RSA-4096 digital signature, Bitcoin blockchain timestamp via OpenTimestamps, and a Provenance Certificate with 8 integrity checks for deepfake detection. Enterprise plans add eIDAS-qualified timestamps issued by Disig a.s., an EU-accredited Qualified Trust Service Provider under Regulation (EU) No 910/2014 — legally presumed accurate in all 27 EU member states. Evidence packages are admissible under FRE 901 (US), eIDAS Article 41 (EU), §371a ZPO (Germany), Article 2712 CC (Italy), and Article 1366 Code civil (France). Pricing starts at $8.99/month with a 7-day free trial requiring a credit card. Used by lawyers, STR hosts, copyright enforcement firms, and compliance teams in 23 countries.

Judges in US v. Vayner, Griffin v. State, and Serrano v. Cruz-Angeles all rejected screenshot evidence. Here's why.
File timestamps can be changed in seconds. Courts know this. Without a blockchain or eIDAS-qualified timestamp, you can't prove when you captured it.
Any screenshot can be edited in 10 seconds with AI. In Sept 2025, a California judge dismissed a case after discovering deepfaked video evidence. Without a SHA-256 hash, there's no way to prove yours is real.
Who captured it? When? On what device? How was it stored? Screenshots don't answer any of these questions. Under FRE 901 and eIDAS Art. 41, digital evidence requires authentication.

ProofSnap evidence package
Don't trust us. Trust the math.
Most web-evidence tools force you to depend on them. ProofSnap evidence is self-verifiable — anyone with the ZIP can confirm authenticity using open standards (SHA-256, OpenTimestamps, eIDAS), with or without ProofSnap continuing to exist.
| ProofSnap | Page Vault / Pagefreezer | Notary / Wayback Machine | |
|---|---|---|---|
| Verifiable without the vendor? | Yes — SHA-256 + OpenTimestamps work forever | No — verification requires their portal | No — depends on archive availability |
| What if the vendor disappears? | Evidence still valid | Evidence becomes hard to defend | Wayback can be wiped on request |
| Independent court-expert verification | Any IT expert, in 60 seconds | Requires vendor cooperation | Requires manual screenshot |
| Cryptographic proof in the file itself | Yes — open standards (SHA-256, OTS, eIDAS) | Proprietary format | None |
“Its merit is based on it being self-verifiable, and not necessarily dependent on the credit or level of trust afforded to the company or institution behind it.”

Independent legal opinion · 21 April 2026
The opinion was prepared by SEDLAKOVA LEGAL s.r.o. (Brno, Czech Bar Association, Company ID 05669871) under EU law (Regulation 910/2014, eIDAS) with reference to Czech civil procedure. Cross-references to the US Federal Rules of Evidence (FRE 901, 902(13)–(14), proposed FRE 707) and the English Civil Procedure Rules (CPR 32, 35) added by the ProofSnap team for orientation of common-law readers.
FRE 901 · FRE 902(13)–(14) · CPR 32 · eIDAS Art. 41
ProofSnap outputs are usable as means of evidence in civil, criminal and administrative proceedings. Authentication satisfied under FRE 901 / 902 in the US, CPR 32 in the UK, and free evaluation of evidence in EU systems — reinforced by US case law (Vayner, Lorraine v. Markel, Mendones).
Notarial deed · Court reporter affidavit
The opinion describes ProofSnap as "a suitable and economical alternative" to notarial fact certification of website state. Court-reporter affidavits and notarial deeds (US $200–500, UK £200–800) require waiting time during which content can disappear; ProofSnap captures immediately with cryptographic integrity.
eIDAS Art. 41(2) · Regulation (EU) 910/2014
The qualified eIDAS timestamp issued by Disig a.s. — Qualified Trust Service Provider on the EU Trusted List — carries the statutory presumption of accuracy of date, time and data integrity, shifting the burden of disproof to the opposing party, directly across all 27 EU Member States.
“The outputs of the ProofSnap service are, from the perspective of Czech procedural law and the EU legal framework, generally usable as means of evidence in any type of proceedings.”
— Conclusion of the legal opinion, SEDLAKOVA LEGAL s.r.o., 21 April 2026
The opinion is publicly accessible, no registration. The conclusions express the legal view of the author and do not constitute binding legal advice.
ProofSnap's eIDAS qualified timestamps shift the legal burden. Under EU Regulation 910/2014, Article 42, your evidence is legally presumed accurate — the opposing party must prove otherwise.

Regular screenshots can be challenged in court because they lack proof of when they were taken and whether they've been altered. Courts increasingly require authentication under rules like FRE 901/902 (US) or equivalent rules in other jurisdictions.
ProofSnap addresses these challenges by creating a forensic evidence package that includes: a SHA-256 cryptographic hash proving the content hasn't been modified, a digital signature for authenticity, a blockchain timestamp proving when the capture occurred, and full metadata (URL, browser info, TLS certificate). This makes your screenshot significantly more defensible than a plain image file.
ProofSnap uses three layers of cryptographic protection:
Together, these mechanisms create a chain of integrity that proves the evidence is authentic, unaltered, and was captured at a specific point in time.
The eIDAS 2 regulation (EU 2024/1183) is fully rolling out by the end of 2026, establishing stricter standards for electronic identification, digital signatures, and qualified electronic timestamps across all EU member states.
Under Article 41, qualified electronic timestamps enjoy a legal presumption of accuracy for the date and time they indicate, and the integrity of the data to which the timestamp is linked. This means evidence timestamped with a qualified service is admissible across all EU courts.
ProofSnap's cryptographic proofs align with eIDAS 2 requirements: SHA-256 hashing for data integrity, RSA-4096 digital signatures for authenticity, and blockchain timestamps via OpenTimestamps for independent time verification. This makes ProofSnap evidence packages suitable for legal proceedings in any EU jurisdiction.
