How to Export iPhone Messages with iMazing

iMazing is a desktop application for Mac and Windows that connects to your iPhone, iPad, or iPod and lets you browse, back up, and export device data, including SMS, iMessage, and RCS conversations. It's not an iPhone-only app; the software runs on your computer, reads a local backup of your device, and presents message history in a browsable interface from which you can export to several file formats.

This guide walks through the complete process: installing iMazing, connecting your iPhone, creating a backup, filtering conversations, choosing an export format, handling attachments, and verifying your output. It also covers RSMF exports (a specialized format for legal and e-discovery workflows) and troubleshooting steps for common problems.

Who this is for: Anyone who needs to export iPhone messages for personal archiving, printing, compliance review, or legal documentation, and has access to a Mac or Windows computer.

Prerequisites: A Mac or Windows PC, a USB cable, and a licensed copy of iMazing (a free trial is available for browsing; exporting messages requires a paid license).

Difficulty: Low to moderate. The process involves installing software, pairing a device, and navigating a desktop UI. No technical background is required.

Estimated time: 20 to 60 minutes depending on backup size.

What iMazing is and when to use it

iMazing positions itself as a desktop tool to transfer, manage, and back up iPhone/iPad/iPod on Mac and PC. The message export feature is one part of a broader product that also covers photos, music, contacts, apps, and battery diagnostics.

Common reasons to use iMazing for messages:

Creating a durable archive of SMS or iMessage history before switching phones.
Producing a readable PDF transcript for printing or sharing with a lawyer.
Exporting structured data (CSV/Excel) for review or analysis.
Generating an RSMF file for ingestion into legal review platforms (requires iMazing Business).

One expectation to set upfront: iMazing doesn't export messages via a simple in-app button on your iPhone. It reads data from a local device backup on your computer. That means you need to create or have an existing backup before message content is accessible. The quality and completeness of your export depends directly on what's in that backup.

System requirements and supported OS versions

iMazing runs on macOS and Windows. Based on iMazing's published compatibility information:

macOS: Requires a supported macOS version (check iMazing's current download page at imazing.com for the exact minimum version, as requirements update with new releases).
Windows: Requires a supported Windows version (similarly, verify on iMazing's download page).
iOS device: iMazing supports iPhone, iPad, and iPod; supported iOS/iPadOS versions are listed on iMazing's Tech Specs page.

Connection requirements: According to iMazing's official connection guide, "Apple devices can be connected to iMazing either via USB or Wi-Fi. However, the initial connection for iPhone, iPad, and iPod needs to be made via USB." After the initial USB pairing, subsequent connections can be made over Wi-Fi if that option is enabled in iMazing's settings.

Step 1: install iMazing and connect your iPhone

Download iMazing from the official site at imazing.com. Choose the Mac or Windows installer that matches your OS.
Run the installer and follow the on-screen prompts.
Connect your iPhone to your computer using a USB cable.
On your iPhone, tap Trust when prompted to trust the connected computer. You may also need to enter your iPhone passcode.
Open iMazing. Your device should appear in the Devices panel on the left side of the application window.

Checkpoint: Your iPhone's name and model should be visible in the left pane. If it doesn't appear within 30 seconds, disconnect and reconnect the cable, then check Step 1 of the troubleshooting section below.

Enabling Wi-Fi sync (optional): Once connected via USB, you can enable Wi-Fi management for future sessions. In iMazing, select your device, go to its settings, and turn on the Wi-Fi sync option. After enabling it, you can disconnect the cable and iMazing will connect over your local network on subsequent sessions.

Step 2: create or select a backup

iMazing states that it relies on a local backup of your device to access its contents. You have two paths:

Option A: create a new backup

Select your device in the left pane.
Click Back Up Now (or the equivalent option in the iMazing toolbar).
Wait for the backup to complete. Backup time depends on how much data is on your device; a full backup can take several minutes to over an hour.

Option B: use an existing iMazing backup or snapshot

In the left pane, look for previously created backups listed under your device.
Select the snapshot that corresponds to the date range of messages you need.

Important: A backup captures message data as it exists at the time the backup runs. If you created your most recent backup six months ago, messages sent or received after that date won't appear in the export. If you need your most recent messages, create a fresh backup before proceeding.

Timestamps and metadata in the export reflect what's stored in the backup, so the snapshot you choose directly affects the output.

Step 3: open Messages and apply filters

In the left pane, select your device or backup.
Scroll down the feature list and click Messages (the icon typically shows a speech bubble or is labeled Messages/SMS/iMessage).
iMazing will load your message threads. Wait for the list to populate.
Click the conversation or contact thread you want to export.
To narrow the export, use the available filter controls. iMazing's export interface includes options to filter by date range and to search within a conversation. Use these to isolate the specific messages you need before triggering the export.

Note on filters: Filtering before export limits the output to the selected range. If you want a full conversation history, skip filters and export the entire thread. If you only need messages between two specific dates, set those date boundaries now to avoid manually trimming the output later.

Step 4: choose your export format (PDF, CSV, TXT, or RSMF)

With your conversation selected and filters applied, click the Export button. iMazing will prompt you to choose a format. According to iMazing's export guidance (updated March 10, 2026), the supported formats for iPhone message export are:

PDF

The PDF output preserves the visual appearance of the conversation, including chat bubbles, timestamps, contact names, emojis, and inline graphics. This format is suited for printing, sharing with attorneys, or filing as a readable exhibit. Page layout is formatted for readability, with participant names and timestamps visible throughout.

CSV / Excel

The CSV export produces a spreadsheet-compatible file with messages organized in rows. Each row typically includes fields such as sender, timestamp, and message body. This format works well when you need to sort, filter, or analyze messages in a spreadsheet application, or pass data to a downstream review tool.

TXT (plain text)

The TXT export produces a raw text file of the conversation. It's a lightweight option for quick reference or when you need to import message content into another system that accepts plain text.

RSMF (Relativity Short Message Format)

RSMF is described by iMazing as "a format for e-discovery, archiving, forensics, and data analysis." It's designed for ingestion into legal review platforms. If you're working on a matter that will be reviewed in a platform like Relativity, RSMF is the appropriate output format.

Licensing requirement: Exporting to RSMF requires an active iMazing Business subscription. The standard consumer license does not include RSMF export. If you're exporting for personal archiving or printing, PDF or CSV will cover most needs without the Business license.

For context on how these formats compare across different tools, the export iMessage chat history guide covers the trade-offs in more detail.

Step 5: handling attachments and metadata

Attachments

iMazing's export guidance notes that it can "export just the attachments to your messages" as part of the export workflow. Depending on the format and options you select, attachments (photos, videos, audio messages, and files) may be included inline in the export or saved to a separate folder alongside the main export file.

When running an export, check the export options dialog for an attachment-handling setting. If attachments are relevant to your purpose (for example, photos shared in a legal dispute), confirm they're included before finalizing the export.

Metadata checklist for legal or compliance workflows

Before treating an export as final for legal or compliance use, verify that the output includes:

Sender names or phone numbers for each message.
Timestamps (date and time) for each message.
Correct chronological order throughout the conversation.
Attachment references or embedded attachments where applicable.

iMazing's PDF format preserves these fields visually. The CSV format includes them as structured columns.

Signing PDFs

iMazing produces the PDF but does not apply a digital signature. If your workflow requires a digitally signed PDF for legal filing or authentication, use a separate signing tool after export. On macOS, Preview supports basic digital signatures. Adobe Acrobat and DocuSign are common third-party options for more formal signing workflows.

For guidance specifically on preparing message exports for court filings, see how to print text messages for court.

Verifying your export

Before using the exported file, open it and check the following:

Conversation order: Messages should appear in chronological order from oldest to newest. Scrambled order is a sign of a filter or export error.
Timestamps: Confirm that dates and times are present and fall within the expected range.
Completeness: If you filtered by date, verify the first and last messages in the export match your intended range.
Attachments: If attachments were expected, confirm they're present in the output or in the companion folder.
Participant names: Both sides of the conversation should be identifiable by name or phone number.

For printing, open the PDF and check that text is readable at standard print size, timestamps aren't cut off at page margins, and participant labels are consistent throughout.

Re-export guidance: If the output is missing messages, the most likely cause is that the backup or snapshot predates those messages. Create a new backup and re-run the export. If you applied filters that may have excluded content, remove or widen them and try again.

For RSMF exports used in legal review, retain the original exported files and document your export configuration (date of backup, filter settings, format selected). This provides a clear record of how the data was collected.

Troubleshooting tips

iPhone not recognized

Make sure you're using a data-capable USB cable, not a charge-only cable.
Tap Trust on your iPhone when prompted. If the prompt doesn't appear, lock and unlock your iPhone after plugging in.
Try a different USB port on your computer.
If using Wi-Fi sync and the connection fails, reconnect via USB to re-establish pairing.

macOS or Windows security prompts

Some macOS security settings (under System Settings > Privacy & Security) can block apps from accessing connected devices. If iMazing can't read your device, check that it has the necessary permissions. On Windows, ensure your firewall or security software isn't blocking iMazing's device communication.

Older messages are missing

This is almost always a backup issue. iMazing reads message data from the backup snapshot you selected. If the backup was created recently and older messages were deleted from your iPhone before the backup, those messages aren't in the snapshot and can't be exported. Check whether an older iMazing backup (created when those messages still existed on the device) is available in the left pane.

Export errors or incomplete output

Make sure iMazing is updated to the latest version. Older releases occasionally have format-specific bugs that are fixed in updates.
For large conversations, the export may take longer than expected. Give it time to complete before assuming an error.
If a specific format fails, try a different format to determine whether the issue is format-specific.

RSMF option not available

RSMF export is locked behind iMazing Business. If the option is grayed out or absent, your current license doesn't include it. Upgrade to iMazing Business to unlock RSMF, or export to PDF or CSV using your existing license.

When a computer isn't an option

iMazing's workflow requires a Mac or PC, a USB connection for the initial pairing, and a paid license. That setup works well for desktop-based workflows or bulk exports of iMessage and SMS history. The trade-offs are real, though: you need the hardware, the cable, and time to create a backup before any export happens. iMazing also doesn't natively read third-party messaging apps like WhatsApp, Instagram DMs, or Telegram.

If you need to export messages from your iPhone without a computer, or from apps beyond iMessage and SMS, TextPort takes a different approach. It runs entirely on iPhone and iPad, uses screen recording or screenshots to capture any conversation that's visible on screen, and produces a PDF, CSV, or plain text file without requiring a cable, a backup, or a desktop computer. That makes it a practical option for WhatsApp, Instagram DMs, Telegram, Signal, Facebook Messenger, and any other app you can scroll through on your device.

The two tools are built for different workflows. iMazing is the stronger option when you want a batch export of iMessage/SMS history from a desktop environment. TextPort is the faster path when you're on your phone, need to export from a third-party app, or don't have a computer nearby.
