Frequently Asked Questions about PNG Metadata
What metadata can PNG files contain?
PNG files contain tEXt chunks, iTXt chunks, timestamps, software information, color profiles, and comments that can reveal personal data.
Is PNG metadata visible?
PNG metadata is not visible in the image but can be read by software and may contain private information like creation software and timestamps.
What are PNG text chunks (tEXt, iTXt, zTXt)?
PNG text chunks store metadata: tEXt holds plain text comments, iTXt supports international text with language tags, and zTXt contains compressed text data. All can leak sensitive information like author names, software versions, and internal comments.
Do PNG screenshots contain system information?
Yes, PNG screenshots often embed your operating system, screen resolution, DPI settings, screenshot tool used, and timestamp. Some tools even add machine names or user paths in metadata chunks.
