Filter Mastodon Content Deletion for Videos, Images, or Links

You can choose to delete content that includes specific media types too. This way you can bulk delete all content that contains specific types of media.

Posts with videos
Posts with images
Posts with links

You can delete specific content by what type of post it was. So for instance you could only delete posts that have a image in them, or posts that have a link or video.

Filter Mastodon Mass Deletion with Keywords or Hashtags

If you want to delete posts with specific text or hashtags, use the “Post Keywords to Delete” option; this gives you even more precision when bulk deleting Mastodon content. You can;

Enter phrases or words found in the body of the post
Add hashtags like #ad or #sponsored to delete all matching posts

This way you can quickly clean up content with promotional messaging, sensitive information, or anything else in the keywords.

Enter a phrase or group of words that Redact will search in the post body to be deleted. If you’re looking to delete content with specific words in the post, this is where you specify it.

Enter a hashtag that Redact will search in the post body to be deleted. This is a easy way to delete anything mentioning a hashtag, for instance #sponsored or #ad .

Mass Deletion Options for Mastodon

Once you’ve set up your deletion filters, you’re ready to start deleting! There are a few types of deletion you can use depending on your needs;

Deletion Mode: this will delete all the matched content at once. To ensure you don’t delete anything you want to keep, we recommend running Preview Mode first and checking the results
Preview Mode: this will run a preview job, showing you all your old content that matches the filters you’ve set. It’s handy for previewing what you’re going to delete, before bulk deleting.
Review & Delete: this option allows for precise, easy deletion of your old content. Redact.dev will show you content matching your filters, then you get to define what content to bulk delete, and what to keep.

You can also use the Scheduler mode to automatically bulk delete Mastodon content! This lets you set up and schedule your deletion to run automatically at a set frequency based on your needs. Note: Redact.dev needs to be left open for scheduled jobs to run.

Mass Delete Mastodon Posts and Replies FAQ

Can I delete all my Mastodon posts in one step inside Mastodon?

Mastodon does not include a single remove all button. You can delete toots one by one per instance. Bulk tools can automate batches with filters you control.

How does federation affect deletion of my posts and boosts?

Deleting on your home instance sends delete events to other servers that received your post. Remote caches can lag or miss updates. Expect some propagation delay.

How do I connect Redact to my Mastodon instance to start a bulk cleanup?

Open Redact and choose Mastodon. Enter your instance domain, sign in, then pick content types such as posts, replies, boosts, media, or DMs where supported. Redact runs on your device and uses the minimum access needed to perform actions you approve.

Which filters can Redact apply for Mastodon deletions in bulk?

Filter by date ranges, keywords, hashtags, visibility such as public or followers only, media types, boosts, replies, and client source. Combine Before, After, Between, or All Time with keyword lists for precision.

What modes does Redact provide for Mastodon cleanups?

Use Preview to review matches, Deletion to remove matches, Review & Delete to approve items, and Schedule Deletion for recurring sweeps during ongoing privacy work.

Can I remove only replies or only boosts and keep original posts?

Yes. Target replies or boosts only. You can also restrict to posts with media, posts with content warnings, or posts that mention specific accounts.

What happens to remote copies and screenshots after I delete a post?

Deletion removes the original and sends a signal to federated servers. Third party screenshots, mirrors, or caches can remain. Use takedown requests where possible.

Does Redact store my Mastodon credentials or post data on its servers?

No. Redact runs on your device and uses the minimum access required to execute your actions. You can disconnect your instance account from Redact at any time.

Should I export my Mastodon archive before doing a large cleanup?

Yes. Request an account archive from your instance if available, or save important threads privately. Store archives offline or in encrypted storage.

How does Redact handle rate limits and very large histories on Mastodon?

Redact batches actions and spaces requests to respect instance limits. For years of posts, run smaller date slices or schedule several passes for stability and coverage.

Can I target posts with certain hashtags, mentions, or content warnings only?

Yes. Use keyword and hashtag filters, mention filters for accounts, and a flag for posts with CW fields. Review in Preview before you delete.

Will deleting DMs in my client remove them for the other person too?

Direct messages can persist for recipients. Removing your side does not guarantee removal from the other inbox. Treat private messages as long lived for others.

Can Redact schedule recurring Mastodon cleanups so new posts do not pile up?

Yes. Save your filters and schedule weekly or monthly runs. This keeps your profile lean during ongoing privacy or brand work.

What is the safest workflow to avoid mistakes with Mastodon deletions at scale?

Export data, run a small Preview, keep a whitelist of hashtags or accounts to keep, approve a short Review & Delete batch, then expand your ranges after you confirm results.

Is Redact easy to try for Mastodon, and how do I sign in securely?

You can download Redact for free and start with recent history. Redact uses passwordless sign in with secure email codes. Upgrade any time for all time cleanups and advanced options.
