If you don't have access to a PC or Mac, give TextPort on the App Store a try. It works directly on the device.

Take screenshot or email the text conversion.

You manually copy the text from your Messages conversation, paste it into a document (Apple Notes or Apple Pages), and then use that app's built-in PDF export feature to create the final PDF file. Both Notes and Pages are free, pre-installed apps on your iPhone.

This approach uses the Notes app as an intermediate destination before you export text messages from iPhone to PDF.

Step 1: Copy the Messages

• Open the Messages app and navigate to the conversation you want to export text messages from iPhone to PDF.
• Tap and hold on a message bubble, then drag the selection handles to highlight the entire conversation or the portion you want to save.
• Tap "Copy" from the popup menu. For long conversations, you will need to scroll and repeat this process in chunks—there is no "Select All" feature for text messages.

Step 2: Paste into Notes

• Open the Notes app. Create a new note by tapping the compose button. Tap and hold in the note body, then select "Paste" to insert the copied messages.

Step 3: Convert the Note to PDF

According to search results, Apple Notes has a built-in PDF export feature . Here's how to use it:

• Tap the Share button at the top of the note
• Scroll down and select "Send a Copy" or "Print"
• If you select "Print," use the pinch-out gesture on the print preview to expand it into a full PDF view
• Tap the Share button again and select "Save to Files" to save the PDF to your iPhone

It lets you save selected messages via email and then convert them to PDF, but it only works with one batch of messages at a time, not entire long conversations.

First, open the Messages conversation you want to export. Press and hold a message, then tap "More...". Select all the messages you want to save. Tap the Share icon, then choose Mail. Send the selected messages to your own email address.

On your PC, open the email containing the messages. Use the print function and select "Save as PDF" to complete the process.

Once saved, you’ll have a PDF file with the selected messages stored permanently.

Cons

• You cannot export an entire long conversation history in a single batch. You must manually select and send messages in batches, which is very tedious for large chat histories.
• The exported content will lose key details such as precise timestamps, sender names, and conversation thread formatting, reducing the usefulness of the generated PDF file for official or legal records.
• Attachments such as photos, videos, or voice messages are not included in the email export, so the final PDF file contains only plain text.
