Create PDF

Turn a WhatsApp export into a professionally formatted PDF. Creating it also captures and stores the export's digital fingerprint, ready for a later DeepCheck. You preview the PDF and set its options before it is created.

Turn WhatsApp messages
into credible evidence

Upload your WhatsApp export and receive a professionally formatted PDF, backed by DeepCheck — a digital fingerprint analysis that uncovers signs suggesting your chat has been edited.

WhatsApp messages are easy to fake and easy to dismiss. Chatsward runs DeepCheck on the metadata structure of your export file and produces a professionally formatted PDF, so when the other side says "that's fake," your chat can stand up against the challenge.

What creating a PDF does

Sets the chat out as a PDF
The messages appear as they do on the phone, with senders, times and dates written as 14 Mar 2025. You choose the template, the date range and whose phone it is shown from, and preview every page before it is created.
Stores the export's digital fingerprint
At the moment the PDF is created, Chatsward captures and stores the export's digital fingerprint. A later DeepCheck examines that stored fingerprint, so you do not need the export file again.
Makes a record others can check
The PDF is given a SHA-256 hash and a trusted timestamp. Anyone handed the document can check it against our records on the Verify page, without an account.
Does not keep your export
The export file is deleted after processing. Its fingerprint and hashes are kept; the PDF downloads to you.

Each PDF uses one PDF generation credit. It appears in your audit trail, under its matter if you give it one.

What's in the PDF

🔬

DeepCheck

DeepCheck scans a WhatsApp export for anomalies. It reads its digital fingerprint and surfaces anything that needs to be reviewed. Findings are presented in plain English alongside the raw data.

⚖️

Professional formatting

Correct font sizes, line spacing, page numbering, and exhibit references. Formatted to meet UK court bundle requirements.

💬

Styled message bubbles

Messages displayed with sender colours, timestamps, emoji, and images, clearly showing who said what and when.

🔒

Private by design

Fully automated processing. No human reads your messages. Your export file is deleted after processing: Chatsward keeps only its digital fingerprint and SHA-256 hashes, so DeepCheck can examine it later.
