Never lose an old conversation. The free Mac app archives your entire Messages history into a portable bundle in your own iCloud Drive — and lets you read it right there. Safely turn on Keep Messages: 1 Year, then open the same archive on your iPhone whenever you like.
archive.imarchive bundle — and lets you browse, search, and open attachments right there.Every chat, every message, every attachment that exists on disk — captured exactly as it was, never modified.
Apple's "Keep Messages: 1 Year" setting deletes anything older than a year from your Mac. Message Keeper captures it all first — so you can turn the setting on, keep your Mac fast, and never lose a conversation.
After your first archive, the app offers to add a yearly calendar reminder. You verify the archive on Mac and iPhone, then you turn on Keep Messages: 1 Year in Messages settings — the archiver never touches that setting. Each following year, you run the archiver again: it merges only the new messages, deduplicates attachments by SHA-256, and is a no-op for everything already captured.
The Mac app is local-only and read-only against your Messages database. The reader — on Mac and iPhone alike — opens the archive from your own iCloud container. There is no server, no account, and no telemetry — the only network traffic is iCloud syncing between your own Apple devices.
The free Mac app does everything — archive and read. The iPhone app is the same reader in your pocket: $0.99/year, first month free. You never need it to read your archive.
Requires macOS 26+ on Apple Silicon · iOS 26+ · Full Disk Access on the Mac.
