How to Backup Your X/Twitter Tweets Locally

People put a lot into their tweets. Ideas, conversations, things they figured out and shared. Over time, a Twitter account becomes a kind of personal archive — sometimes going back five or ten years.

But tweets are not permanent. Accounts get locked. Platforms change what is accessible. People decide to leave a platform and want to take their writing with them.

Even if none of that happens, having a local copy of things you wrote is just good practice. Like keeping your own photos instead of only having them on Instagram.

PostKeeper helps you export your own X/Twitter timeline — your posts, replies, and threads — into local files you can keep.

Why backup your own tweets?

There are a few common reasons:

• You want a searchable archive of everything you have posted
• You are planning to leave X/Twitter and want to take your content with you
• You want to browse your old posts offline, without scrolling through the app
• You want to import your tweets into a note-taking tool or personal knowledge base
• You are a writer, researcher, or creator and your tweets are part of your work
• You just want a backup — in case something happens to your account

The common thread: your tweets matter to you, and keeping them inside one platform is a risk you do not have to take.

What can you actually save?

When you export your timeline with PostKeeper, you get:

• Your posts (tweets)
• Your replies to other people
• Threads you wrote
• Available media references (images, videos)
• Post metadata — dates, links, engagement counts

You get the content that is accessible from your logged-in browser session. PostKeeper works with what X/Twitter shows when you visit your own profile.

What formats can you export to?

PostKeeper supports several export formats. The right one depends on what you plan to do with your backup:

• Markdown — Best if you want to import your tweets into Obsidian, Notion, Logseq, or a personal notes system. Clean, editable, and portable.
• PDF — Best for a read-only archive. Good for keeping a snapshot of your timeline that looks like a document.
• HTML — Best for a browser-friendly archive you can open anywhere without extra software.
• CSV — Best if you want to sort, filter, or analyze your posts in a spreadsheet.
• JSON — Best for developers who want structured data for scripts or custom tools.
• ZIP — Packs everything together, useful if you want multiple formats in one download.

For most people doing a personal backup, Markdown or PDF is the simplest choice. Markdown if you want to keep using the content, PDF if you just want to have it.

How to backup your tweets with PostKeeper

The process is straightforward:

1. Install the PostKeeper Chrome extension.
2. Open X/Twitter in your browser and sign in.
3. Go to your own profile page.
4. Open PostKeeper and select your profile timeline.
5. Start the export.
6. Pick your format — Markdown, PDF, HTML, CSV, JSON, or ZIP.
7. Save the file to your device.

That is it. Your tweets are now a local file you can store, search, and read however you want.

Your data stays on your device

PostKeeper works locally in your browser. It does not upload your tweets to a cloud server or require you to create an account on another platform.

The export happens through your own logged-in X/Twitter session, and the resulting files are saved directly to your device.

This matters for privacy. Your tweet history can be personal — private conversations, work discussions, things you shared in a specific context. A local-first tool means you are not handing that data to a third party just to get a backup.

Can you refresh your backup later?

Yes. You can run the export again any time to capture new tweets you have posted since your last backup.

PostKeeper also keeps an archive in your browser so you can re-export without fetching everything from scratch. This is useful if you post regularly and want to update your local copy every few weeks or months.

Who should do this?

Backing up your tweets is useful for anyone who posts things they would not want to lose. It is especially relevant for:

• Writers and journalists who publish work on X/Twitter
• Researchers and academics sharing findings and discussions
• Developers who use Twitter for technical conversation
• Founders and makers documenting their building process
• Anyone who has been on Twitter for years and has a history worth keeping

If you have ever searched your own profile trying to find an old post, you already know why a local backup helps.

Is PostKeeper affiliated with X or Twitter?

No. PostKeeper is an independent tool and is not affiliated with X Corp. or Twitter.

Backup your tweets today

Your Twitter history is probably more valuable than you think. It is a record of what you thought about, worked on, and shared — sometimes over many years.

A local backup takes a few minutes and gives you something you cannot get from the platform: a copy of your own content that you control.
