Someone posted something that matters to your situation — a threat, an admission, a defamatory claim, a photo that contradicts what they're now saying — and you're worried they'll delete or edit it. On social media that can happen in seconds, and once it's gone, no tool can recover what you didn't save. So before anything else: capture it now. Read the rest of this after you have a copy in hand.
Then make the copy one a court can actually use. Social media evidence gets challenged more aggressively than almost any other kind, so the way you preserve it matters. Here's what to do.
A tight crop of just the words is the easiest thing in the world to attack, because it strips away everything that ties the post to a person and a moment. Capture the full view: the account name and handle, the profile photo, the post's own timestamp, any thread or replies around it, and the URL of the specific post (most platforms give each post its own link — open it and grab that page, not just the feed). If it's a story or anything that auto-expires, treat it as already disappearing and capture immediately.
To be admitted, evidence has to be authenticated — under Federal Rule of Evidence 901(a), whoever offers it must show "evidence sufficient to support a finding that the item is what the proponent claims it is." (Most states track this; check your rule.) Courts have been openly skeptical of social media precisely because accounts can be faked and posts can be spoofed. In the leading case Griffin v. State, 419 Md. 343 (2011), Maryland's highest court threw out a MySpace printout, holding that social-network evidence "requires a greater degree of authentication" because of "the potential for fabricating or tampering with electronically stored information." The takeaway isn't that social media is inadmissible — it's admitted routinely — but that a bare screenshot with nothing behind it is the weakest possible version. The more you can show about who posted it and that your copy is unaltered, the better.
The most common way to authenticate is simple testimony from someone with knowledge (Rule 901(b)(1)), often reinforced by distinctive characteristics that point to the author — the account name, profile details, prior posts, or content only that person would know (Rule 901(b)(4)). So record, while it's fresh: the exact post URL, the account name and handle, the date and time you captured it (note your time zone), the device and app or browser you used, and how you found it. A contemporaneous note is far more persuasive months later than "I think it was sometime in June."
Save the original capture and don't touch it: no cropping, no annotations, no re-saving through a photo editor. If you need to mark it up, work on a copy and keep the untouched original.
In plain terms: if your capture has a cryptographic hash (such as SHA-256) recorded at the moment you made it, anyone can later recompute that hash and confirm the file hasn't changed since. It doesn't guarantee admission, but it directly answers the objection social media evidence draws most — "how do we know this wasn't doctored?"
Users delete their own posts, platforms remove content on their own schedules, and edit features quietly rewrite history. Two backups beat one. The Wayback Machine can snapshot many public pages on demand, and the Internet Archive offers an affidavit service for authenticating its records in litigation — but it only captures what it can reach, and login-walled or heavily dynamic social feeds often don't archive well. If the account is public and the stakes are high, you can also send the platform a preservation request or, in a matter already in litigation, have counsel subpoena the records directly from the platform (which is also, per Griffin, one of the strongest ways to authenticate). Your own timestamped copy is what protects you in the hours before any of that happens.
Honesty matters more than sales copy here: no capture tool, ours included, can guarantee a court will admit your evidence. Admissibility is decided by the judge under your jurisdiction's rules, and authentication is only one hurdle — hearsay, relevance, and completeness objections exist too. Private content — DMs, private groups, disappearing messages, texts — can't be reached by third-party webpage tools at all; for those, screen-record or photograph the thread on the device and preserve the device itself. And for serious litigation or criminal matters, talk to a lawyer about formal forensic collection and preservation letters. For small claims and everyday disputes, judges tend to be more flexible — but a well-documented, hashed capture still beats a bare screenshot every time.
This is general information, not legal advice, and admissibility is always decided by the court under the rules of your jurisdiction. ProofSnap preserves public webpages with a timestamp and integrity hash; it does not and cannot guarantee that any capture will be admitted as evidence, and it cannot access private or login-gated content.
