Remove Metadata from PNG

PNGs carry metadata too — text chunks written by editors, modification timestamps, and sometimes a whole embedded EXIF block. Remove them all locally.

Why this matters

People assume PNGs are "clean" because they often come from screenshots or graphics tools, but the PNG format has dedicated metadata chunks: tEXt, iTXt and zTXt for arbitrary text, tIME for the last-modified timestamp, and eXIf for an embedded EXIF block just like a JPEG.

Image editors and export pipelines routinely stamp these chunks with the software name and version, an author or copyright string, a creation timestamp, and occasionally generation prompts or comments — details you may not want attached to a file you publish.

MetaScrub keeps only the chunks a PNG needs to render — IHDR, palette, image data, transparency, colour profile — and drops every metadata chunk. The image is bit-identical; the text, timestamp and EXIF chunks are gone.

What this metadata leaks

How to do it with MetaScrub

1. Open the MetaScrub cleaner and drop your PNG onto the drop zone.
2. Review the listed metadata — MetaScrub surfaces tEXt/iTXt text chunks (software, author, comments), the tIME timestamp and any embedded eXIf block.
3. Click "Clean" to drop every metadata chunk while keeping IHDR, palette, image data, transparency and colour profile. It runs locally; nothing uploads.
4. Download the cleaned PNG — bit-identical to view, with the text, timestamp and EXIF chunks removed.
