A screenshot is not evidence.You need a forensic capture.

A plain screenshot can be altered in seconds and rarely holds up as a screenshot as evidence. TrueSnap is forensic web capture: an authenticated, court-admissible screenshot that keeps the original capture—hash-verified, timestamped, and packaged with HAR and TLS logs.

Why courts reject plain screenshots

Digital evidence needs integrity of origin, content, and time

No proof the page is unaltered

Anyone can open browser developer tools (F12) and rewrite the text, numbers, or images on a page in seconds. A screenshot of that altered view looks identical to the real one — so a tampered image can pass as 'evidence'. Ordinary capture apps and extensions can't really stop this.

No proof of when it was taken

The 'date created' on a file can be changed with just a few clicks. Without an independent record that anyone else can verify, it's hard to prove exactly when a screenshot was actually captured.

No proof of where it came from

Even if a screenshot looks right, you also need to show it really came from that website. Without a record of the address you visited, the data you received, and the security certificate involved, the source can't be objectively proven. TrueSnap saves all of that context together with the capture so the entire collection process can be explained.

TrueSnap preserves the original, exactly as-is

With multi-layer proof, origin · content · environment · time are all verified objectively

01

Origin & network integrity

The dedicated browser records every request and response made to the site, along with the TLS certificate verification result. External proxies and man-in-the-middle attempts are blocked automatically, so we can objectively show the page truly came from that website.

02

Content integrity

Every artifact — screenshot, page source, network log — gets its own SHA-256 fingerprint (hash). If any file is altered later, even by a single character, the fingerprint won't match, so tampering is detected immediately.

03

Environment & tool integrity

Developer tools that could be used to modify the page are completely disabled, and any tampering attempt is caught by built-in detection. The capture app itself is also verified at launch to confirm it hasn't been altered, ensuring the entire capture environment can be trusted.

04

Time & external attestation

The evidence fingerprint is anchored on a tamper-proof blockchain so a third party can objectively verify exactly when it existed. The user's interaction flow and environment information at the moment of capture are also recorded, and everything is bundled into a forensic certificate that's ready to submit to courts or internal review.

Designed by a Supreme Court forensic expert

Built by an expert who knows what courts require

TrueSnap was designed by a certified forensic examiner who performs special forensic assessments for the Supreme Court. It's not just a capture tool — every feature was built from the ground up to meet the standards courts demand for digital evidence.

For digital evidence to be admissible in court, you need to prove the authenticity of its origin, the integrity of its content, and an objective timestamp. Having worked on numerous forensic examination cases, I've seen firsthand why ordinary screenshots fall short — so I built a tool that structurally guarantees all three.
Performs digital forensic special assessments for the Supreme Court
Extensive hands-on experience in digital evidence integrity verification & analysis
Evidence package structure reverse-engineered from court forensic report standards
Multi-layer tamper prevention: SHA-256 hashing, blockchain anchoring, and more

Designed to court evidence standards

Structurally designed to satisfy the three requirements courts demand for digital evidence: authenticity of origin, content integrity, and time attestation.

Real forensic expertise built in

HAR network logging, TLS verification, DOM tampering detection — all defense layers are grounded in real-world forensic examination experience.

Backed by a certified examiner

From evidence collection to certificate issuance and blockchain anchoring, every step is personally reviewed and refined by a forensic professional.

Frequently Asked Questions

Forensic capture—also called a forensic screenshot or forensic web capture—is a webpage saved in a controlled browser so you can later prove it was not altered. TrueSnap records the image plus HTML, HAR (network log), SHA-256 hashes, and a blockchain timestamp. That is not the same as a phone or OS screenshot.

You can tender a screenshot, but courts and opposing counsel often ask whether it is authentic. Legal evidence capture needs origin, integrity, and time. TrueSnap builds a court-admissible screenshot package so counsel can explain those three points. Admissibility still depends on the case—ask a lawyer.

An original capture (authenticated or hash-verified screenshot) is a file set you can re-hash to show nothing changed after collection. A regular screenshot’s date can be edited, and the page can be rewritten with developer tools before you hit capture.

Use webpage preservation / forensic web capture before the post is deleted. Capture the full page with the URL visible, keep the whole package (do not split files), and store a timestamped, tamper-evident copy. TrueSnap does this in one click on your computer.

Plain screenshots are easy to fake with devtools. TrueSnap captures inside a dedicated browser with devtools structurally off, then writes HAR, per-file hashes, integrity logs, and a certificate to a local folder so you can explain and verify what was collected.

Yes. You just need to sign in yourself inside the TrueSnap browser window.

Yes. Every capture's evidence fingerprint (hash) is automatically anchored on a tamper-proof blockchain, allowing any third party to objectively verify the time of capture. It's enabled by default on every plan with no extra configuration required.

TrueSnap automatically anchors the SHA-256 fingerprint (evidence hash) of every capture to the Polygon (PoS) mainnet. Anyone can verify it independently with these steps: 1) Open the PDF certificate and find the "Blockchain Anchor" section. It lists ▲ Network: Polygon (Chain ID 137) ▲ Transaction Hash (TXID, a 66-char string starting with 0x) ▲ Block Number ▲ Anchored Hash (the SHA-256 evidence fingerprint) ▲ Anchored At (timestamp). 2) Go to Polygon's official explorer at https://polygonscan.com and paste the Transaction Hash into the search box, or visit https://polygonscan.com/tx/<TXID> directly. 3) On the transaction detail page, confirm that "Status: Success", the "Block", and the "Timestamp" all match the values printed on the PDF certificate. 4) Expand "Input Data" near the bottom (or "More Details → Click to see More → Input Data") and switch "View Input As → UTF-8" (or keep it as raw Hex). You will see the same Anchored Hash that is printed in the PDF — proving that this exact hash was recorded at this exact time and block on-chain. Note: the evidence package folder also stores the same information in blockchain-receipt.json (TXID, block number, contract address, anchored hash, etc.), so you can perform the same lookup and cross-verification without the PDF.

TrueSnap provides a dedicated-environment narrative, hashes, network and integrity logs, and a certificate. Admissibility still depends on jurisdiction and case facts—consult counsel.

No. The capture itself happens locally in the dedicated browser. Your web account (credits, billing) is separate and handled only as needed to operate the service.
