PNG files store invisible data in named "chunks" alongside the pixel data. Most of these ancillary chunks are harmless, but several carry information you may not want to share publicly when uploading to websites, social media, or clients.

DPI, print size, and pixel offset metadata
When you take a screenshot or save a PNG from Photoshop, Figma, or any editing tool, the resulting file often contains invisible metadata beyond the image itself. This data can reveal details you did not intend to share.
Common situations where this matters: uploading design mockups to clients (software watermarks in metadata), sharing screenshots on social media (device info embedded), submitting PNG files to freelance platforms, publishing images in legal or HR documents, or distributing logos and brand assets where embedded author data is unwanted.
Our tool detects exactly which metadata types are present before stripping, so you can see precisely what each file contained. Pixel quality is always preserved - only the invisible ancillary chunks are removed.
