A screenshot, a phone photo of a screen or a screen recording shows what appeared on one person's screen. It cannot show that the website ever sent that content. Today almost anyone can produce a perfect copy of any page, so the moment the other side says “that's fake”, the image alone has little left to stand on.
None of this needs special skill any more. We describe it so you understand the risk, not how to do it.
Every desktop browser has built-in developer tools that let a user change any text, name, date or number on a page before taking the screenshot. The result looks exactly like the real site, because it is the real site's design.
With the page's own layout and styles, a page can be reproduced pixel for pixel on another server and filled with invented messages. A computer-savvy friend, or simply an AI assistant asked for help, can do this in minutes.
Image generators can produce plausible chats, posts and photos from a sentence of text. These are less exact than a rebuilt page, but good enough to sow doubt.
The federal evidence rules committee has drafted a rule for suspected deepfakes, noting that anyone can now make one cheaply. It is not adopted yet, and a 2026 survey found only about 2% of federal judges had faced a deepfake challenge so far. The direction is clear: when an image is credibly challenged, the party relying on it will have to do more to prove it is authentic.
Official guidance to judges warns that AI tools are being used to produce fake text, images and video. In 2023 an employment tribunal found WhatsApp screenshots had been deliberately faked, and treated that party's evidence with considerable suspicion.
Europol's report on deepfakes notes that courts usually trust audio-visual evidence, lists falsifying electronic evidence as a criminal use of the technology, and calls for a clear chain of custody for digital evidence.
As early as 2011 Maryland's highest court reversed a conviction because social media printouts were not authenticated, and pointed to obtaining the information from the site itself. In 2025 a California court dismissed a case after finding that video and image exhibits were AI-generated.
Under the draft US rule, a bare claim is not enough: the challenger “must present evidence sufficient to support a finding of such fabrication”. Against a self-made screenshot that is often easy: one inconsistency, a timeline that does not fit, or an expert explaining how simply such an image is made.
Then the item is admissible “only if the proponent demonstrates to the court that it is more likely than not authentic”. With a screenshot alone, all you can offer is your own word. An independent capture from the real server, sealed by a third party, answers this step directly.
The rule is a draft, held in abeyance while the committee studies how often deepfakes appear. Belgian and French courts have no such rule but weigh evidence freely, and a disputed screenshot loses weight there too, as the case law shows.
Quotes from the Advisory Committee on Evidence Rules, draft Rule 901(c), report of 1 December 2025.
A qualified timestamp on a screenshot you made proves that the image file existed, unchanged, from that moment. It says nothing about whether the website ever showed it, because the image came from your device. That is useful for your own photos and documents, such as damage photos or a contract. It does not make a screenshot of someone else's website trustworthy.
An independent provider loads the page in its own clean browser, on its own servers. You are not the source of the image, so the question “did you edit it?” does not arise.
The encrypted network traffic is recorded, so the package shows which server sent the content, over a secure connection, at that moment. A copy rebuilt elsewhere would come from a different server.
A qualified electronic seal and a qualified time-stamp from an EU trust service fix the content and the time. Any later change breaks the seal.
A lawyer, bailiff or expert can verify the package with standard tools. A bailiff's report is the other independent route, at €300 to €700.
Courts still admit screenshots, especially when nobody disputes them; see our case-law overview. The problem starts when the other side does dispute them, and that is exactly when you need the evidence most.

Record it with instantproof: an independent capture from the real server, sealed and time-stamped. €0.95 per web page, €10 per recorded chat or session.
