Remove Metadata From a PNG
PNG files carry metadata in text chunks (tEXt, iTXt, zTXt) and can embed EXIF and XMP. This tool parses the chunks and removes the metadata ones - keeping IHDR, the image data and IEND intact - so the PNG stays valid and pixel-identical. Processed locally in your browser - nothing is uploaded.
What gets removed
PNG is the format AI image tools write the most into, so a single PNG can hide an entire prompt, model list and node graph in its text chunks. Even non-AI PNGs pick up editor comments and timestamps. Removing the metadata chunks leaves a clean image that gives nothing away.
- tEXt / iTXt / zTXt text chunks
- Embedded ComfyUI "workflow" and A1111 "parameters"
- eXIf (EXIF) and XMP blocks
- tIME timestamp and other ancillary chunks
- C2PA / private manifest chunks
Frequently Asked Questions
About stripping EXIF, GPS, AI workflow data and other embedded metadata.
No. The tool keeps the critical chunks (IHDR, PLTE, IDAT, IEND) byte-for-byte and only drops the metadata chunks, so the image is unchanged.
A full clean also removes the embedded iCCP color profile, since it is metadata too. If you only want to remove a specific category (say GPS or AI traces), the focused removal modes leave the rest of the file, including the color profile, in place.
