Quick answer

How do I turn a WhatsApp conversation into court-ready evidence?

Export your WhatsApp chat (open the chat, use Export chat, and choose Include or Attach media), send it to ProofSnap, and we deliver a certified package within 24 hours. We render a readable, line-numbered transcript so you can cite a specific message, hash every file with SHA-256, sign the manifest, anchor it in the Bitcoin blockchain and add an eIDAS qualified timestamp. The raw export is preserved untouched. One conversation is $59.99.

What it proves: that your export existed in that exact state no later than the timestamp, and that it has not changed since it was sealed. What it does not prove: who wrote a given message. Authentication of origin stays with the court. ProofSnap is an evidence tool, not legal advice.

Why a WhatsApp screenshot will not hold up

You may already hold the decisive evidence in your case. The problem is the form it is in. Certification fixes all four weaknesses.

"Anyone could have edited this"

A screenshot or a copy-pasted export is trivial to alter. Without a cryptographic hash the other side can dismiss it as unverifiable, and the burden is on you.

No provable point in time

A file on your computer has no independent date. Certification anchors it in time with a Bitcoin OpenTimestamps proof and an eIDAS qualified timestamp that carries a legal presumption.

Disappearing messages

WhatsApp supports disappearing messages and delete-for-everyone, and the other party can delete their account. Export and certify now, while the conversation still exists on your device.

No chain of custody

A raw export is missing the metadata, custodian declaration and integrity record that authentication needs (FRE 902(14)). We preserve the raw export and add all of it.

From "I have the chat" to court-ready, in four steps

A done-for-you service. You export and send, we do the rest, you receive the sealed package within 24 hours.

Step 1 in detail

How to export your WhatsApp chat

WhatsApp has a built-in per-chat export on your phone (iPhone and Android) and in the WhatsApp Desktop app (Mac and Windows). Here is the exact path for each.

On WhatsApp Desktop (Mac and Windows)

Export from WhatsApp Desktop

In the WhatsApp Desktop app on Mac or Windows, open the chat, then:

  1. 1Click the contact or group name at the top to open the Info panel, then scroll down and click Export chat.
  2. 2Choose Attach media (recommended) or Without media.
  3. 3The file is saved straight to your Downloads folder (a message confirms "Exported chat was saved to Downloads folder"). Send us that .zip.

You get the same _chat.txt plus media as the phone export. Desktop is easiest when the chat is on your computer or is too large to email from a phone.

On your phone (iPhone and Android)

Get your chat out of WhatsApp

On iPhone: open the chat with that person or group, then:

  1. 1Tap the contact or group name at the top to open contact info.
  2. 2Scroll down and tap Export chat.
  3. 3Choose Attach media (recommended) or Without media.
  4. 4Choose where to save or send it: Save to Files, AirDrop, Mail, or another app.

On Android: open the chat with that person or group, then:

  1. 1Tap More options (the three-dot menu at the top right).
  2. 2Tap More, then Export chat.
  3. 3Choose Include media (recommended) or Without media.
  4. 4Choose how to send it: Message, Mail, or another app.

One Attach media export gives you a .zip with the _chat.txt plus the media, all at once. Send us that. Very large chats are the only exception: Attach media caps at about 10,000 messages, so also run a Without media export (about 40,000) for the fullest text and send both.

Send us everything (recommended)

The primary artifact is the _chat.txt export plus its media folder. For the strongest exhibit, if available also send the WhatsApp message database. We seal whatever you send, hashed and timestamped, never opened. If authenticity is ever disputed, a court-appointed technician can verify the transcript against the source. Decrypting the database needs its key, which the custodian provides separately.

Optional: the message database

Find your device below, then send us the folder it points to. When in doubt, send more rather than less.

Android phone

Connect by USB and copy the whole WhatsApp folder:

Android/media/com.whatsapp/WhatsApp/ (older devices /sdcard/WhatsApp/)

  • •Databases/: take msgstore.db.crypt15 and every dated msgstore-...crypt15 backup
  • •Media/: the attachments

Your 64-digit key: WhatsApp › Settings › Chats › Chat backup › End-to-end encrypted backup.

iPhone

The store lives inside a device backup, so make a full local backup:

  • 1.Plug into a Mac (Finder) or Windows PC (Apple Devices / iTunes)
  • 2.Tick Encrypt local backup, set a password, back up
  • 3.Send the whole backup folder:
    ~/Library/Application Support/MobileSync/Backup/ (Mac)
    %APPDATA%\Apple\MobileSync\Backup\ (Windows)

Encrypting the backup is what keeps the WhatsApp data complete.

Mac (WhatsApp Desktop)

Zip this whole folder as-is (needs Full Disk Access):

~/Library/Group Containers/group.net.whatsapp.WhatsApp.shared/

It keeps these together:

  • •Messages: ChatStorage.sqlite with its -wal and -shm sidecars (deleted and recent messages can live only in -wal)
  • •Attachments: Media/ and Message/ folders
  • •Who is who: ContactsV2.sqlite and LID.sqlite
  • •Calls: CallHistory.sqlite
  • •Keys and identity: Axolotl.sqlite and enc-key.dat

Too large to zip whole? Send at least these five, each .sqlite with its -wal and -shm.

Windows (WhatsApp Desktop)

Zip the whole folder for whichever build you have:

  • •Store / older app:
    %LOCALAPPDATA%\Packages\5319275A.WhatsAppDesktop_cv1g1gvanyjgm\LocalState\
    SQLite files with their -wal / -shm and cached media
  • •Newer WebView2 build (default since late 2025) and website installer:
    %APPDATA%\WhatsApp\
    including IndexedDB\file__0.indexeddb.leveldb\ (all .log / .ldb files), plus Local Storage\ and Cache\

Not sure which you have? Zip both paths if present, or just tell us.

Your files stay encrypted. Keep your key or backup password yourself. We seal everything exactly as sent, hashed and timestamped, and never open it. You only hand the key to a court-appointed technician if authenticity is ever disputed.

Export chat greyed out or missing?

Two things can hide the in-app Export chat. It is unavailable in Germany (and may be limited in a few other regions). It is also disabled when Advanced Chat Privacy is turned on for that chat, and in a group only an admin can switch it off. Turn Advanced Chat Privacy off (or ask the admin) and export again, or use a device backup, or just email us. Exported chats cannot be re-imported into WhatsApp, which is fine: we only need the export.

See WhatsApp's guide to exporting your chat history.

WhatsApp's "Request account info" (Settings, Account) returns account metadata, not your messages, so the chat export is what carries the conversation. From a full export we transcribe only the one conversation you ask for; the rest is sealed for integrity but never transcribed. After we deliver your finished package, we delete all your data from our servers. Not sure what you have? Email support@getproofsnap.com before you order and we will guide you.

What you get back

The centrepiece is a human-readable transcript: we convert your WhatsApp _chat.txt export (plus media) into a clean, line-numbered transcript PDF you can actually hand to a court. Around it sits a signed ZIP built for admissibility, and we email you an Evidence Delivery Note alongside it.

Everything is verifiable by anyone, for free, in the open Trust Verifier.

The conversation transcript (rendered from your export)

A raw _chat.txt export is not something you hand a judge. We parse it and produce a Chat Conversation Transcript PDF: every message in original send order, by timestamp, with each entry numbered in the left margin so you can cite "Line 47" in a filing.

Cover sheet: parties, case reference, date range, message count, source file and source SHA-256

Faithful rendering: nothing added, altered, reordered or omitted (not a selective extract)

Deleted messages shown as markers; attachments referenced by file name and type

Methodology, time-zone (UTC) and scope-of-proof notes included for the court

Inside the signed evidence ZIP

files/ProofSnap_Transcript.pdf files/_chat.txt (raw export) files/db (sealed source, if provided) manifest.json manifest.sig publickey.pem manifest.json.ots manifest.json.tsr eidas_validation.json chain_of_custody.json forensic_log.json provenance_certificate.pdf

Preserved raw export

Your original WhatsApp export is kept untouched alongside the transcript, so it can be re-derived and independently verified.

Sealed source database

Send the WhatsApp message database and we seal it too, hashed and timestamped but never opened, so a court-appointed technician can later verify the transcript against it.

Two timestamp layers

Bitcoin OpenTimestamps anchor plus an eIDAS qualified timestamp from Disig. We email a delivery note carrying the ZIP SHA-256.

Two layers of proof, and what each one means

Both layers are included in every certification. The qualified timestamp is what carries legal weight in the EU.

Bitcoin OpenTimestamps

The SHA-256 hash of your sealed manifest is anchored in the Bitcoin blockchain: a decentralised, independent, tamper-resistant proof that the export existed at a point in time. Subject to the court's free evaluation of evidence.

eIDAS qualified timestamp

Court-grade in the EU

Issued by Disig a.s., a Qualified Trust Service Provider on the EU Trusted List. Under eIDAS Article 41(2) it carries a presumption of accuracy of the date and integrity of the data: the other side has to rebut it.

Honest positioning (this matters)

What certification proves

  • The export existed in that exact state no later than the timestamp.
  • It has not been altered since it was sealed.
  • The raw export is preserved for later expert examination.

What it does not do

  • It does not prove who wrote a given message.
  • It is verifiable preservation, not a forensic acquisition of the device.
  • Admissibility and weight are decided by the court.

The court assigns authorship, as it always does. Our job is to make the content, order and timing impossible to dispute, so the fight is about what the messages mean, not whether you faked them.

Built to support authentication under FRE 901 and self-authentication under FRE 902(14) (certified data plus hash values), and the eIDAS Article 41(2) presumption in the EU. ProofSnap is an evidence tool, not legal advice. For your specific case, consult a qualified lawyer.
