Bring your microblog posts
to the open web.

Opal converts your posts from Twitter, Mastodon, Threads, and Nostr into Bluesky posts — so your words stay with you, not the platforms.

Import your tweet archive from Twitter's data export file.

Convert your ActivityPub outbox or CSV export from any Mastodon instance.

Bring over your Threads posts from Meta's data export.

Convert your Nostr text notes (kind 1 events) to Bluesky posts.

Links, mentions, and hashtags are converted to ATProto facets where possible.

Everything runs in your browser. No data is sent anywhere except your own PDS.
