Messenger JSON to PDF without uploading your chats

Converters for Messenger JSON are mostly paid desktop programs or websites that want your chats uploaded. A browser can do the job: open the chat in a reader, print it, and choose Save as PDF.

1. One chat to PDF, free

  1. Open your download in Readback: the ZIP, the unzipped folder or the message_1.json files.
  2. Pick the chat. Set "Your messages are from" to your name so your messages sit on the right.
  3. Press Print this chat. Readback lays out the whole chat, first message to last, with its photos.
  4. In the print window choose Save as PDF as the printer. Turn on Background graphics under More settings to keep the blue of your own messages.

Videos and voice messages cannot go on paper; the PDF names them where they were sent.

2. Every chat at once (Pro)

Readback Pro saves one ZIP with every chat as a page that opens offline, its photos, videos and voice messages beside the messages, plus a contents page. Open any chat page in a browser and print it to PDF the same way. The same ZIP has every message in one spreadsheet, with the date, time, UTC time, sender, text, attachments and reactions, which is the form a lawyer or a court usually asks for.

Tips for a clean PDF

  • Long chats: a chat of tens of thousands of messages makes a PDF of hundreds of pages. Search for the part you need first, or keep the text file instead.
  • Time zone: times are shown in your computer's time zone. Say so if the PDF is evidence, or use the UTC column of the spreadsheet.

Open a chat from your download and save it as a PDF from the print window.

Questions

Can I convert Messenger JSON to PDF online without uploading it?

Yes. Readback reads the files in your browser and you save the PDF from the browser's print window. Nothing is sent to a server.

Will the PDF show emoji and accents correctly?

Yes. Readback repairs the codes Meta writes for them before the chat is laid out, so the PDF shows the text as it was sent.

Can I print only part of a chat?

In the print window, choose Pages and type a range. To find the right part, search the chat in Readback first, then print and pick the pages around it.
