A Python tool that packs up to 3MB of arbitrary data into a PNG polyglot file that survives upload to Twitter and other image hosts. It exploits the fact that Twitter preserves trailing data in the PNG IDAT DEFLATE stream when the image avoids re-encoding.

Use cases

• hide a zip file inside a tweetable png
• smuggle files through twitter as images
• create png polyglot files that are also valid zips
• embed data in images that survives image host reprocessing
• share files via social media image uploads

When to choose

• you need to pass data through Twitter, Imgur, Discord, or GitHub image hosting
• you want a valid PNG that is simultaneously a valid ZIP or other file format
• you're researching steganography or polyglot file techniques

When to avoid

• you need steganography that hides data from visual inspection of the image itself (this appends data, it doesn't blend it in)
• your target platform re-encodes images, like Reddit
• you need files larger than ~3MB
