Can a LINE chat be used as evidence?

Whether a chat is admitted is for the court, and convokeep cannot guarantee it. This service only produces formatting prepared for submission, with an integrity hash; it is not legal advice.

How is this different from screenshots?

The whole chat goes into one PDF in date order, with page numbers and an integrity page. That is easier for a lawyer or the other side to check than a stack of screenshots.

Should I talk to a lawyer?

For a real dispute or court case, yes, if the outcome matters. How to submit and what material is needed differ by case and by court.

How to Make a PDF When Keeping a LINE Chat as Evidence

When a chat becomes important in a dispute, a pile of screenshots is hard to read and hard to check. Export the chat history and turn it into a Record PDF in the convokeep app, and it gets page numbers, dates and times, senders and an integrity page. It provides formatting prepared for submission, with an integrity hash; whether a chat is admitted is for the court. Not legal advice.

What you get

The Record layout gives each message a date, time and sender, and numbers the pages. The integrity page at the end lists the source SHA-256, the transcript SHA-256, the message count and the generation time in UTC. The PDF's own hash cannot sit inside the PDF, so it is shown in the app and in the accompanying .sha256.txt file.

Export steps

Export the chat history in LINE. Phone: "≡" → "Others" → "Export chat history"; PC: "≡" → "Save chat". Menu names vary by version (needs verification).
Keep the exported .txt as it is, without editing it. Work from a copy.
Choose Record on this page, build the PDF, and keep the .sha256.txt and the hash values.
If you saved the file on your phone, move it to your computer. Send it by email to yourself, a cloud drive, USB, or whatever is easiest, then drop it in.

A later copy whose SHA-256 hash matches the recorded hash has not changed since that hash was recorded. This does not show that the original chat is authentic or complete. For more, see Chat PDF integrity hash.

Privacy

Reading the file, building the PDF and calculating hashes all happen in your browser. No chat or attachment is uploaded and there is no account. The site counts visits and exports with cookieless analytics, and those events never contain message text, names or file names. Read the full privacy policy.

Keepsake vs Record

Keepsake uses a book-style layout suited to memories and printing. Record adds page numbers, sender and time, and an integrity page with the source SHA-256 and transcript SHA-256 hashes (the PDF's own hash is supplied separately). Prepared for submission, with an integrity hash. Not legal advice. Whether it is accepted is decided by the court or agency. Read the disclaimer.
