PNG Metadata Remover
PNG files store metadata in named chunks. AI tools write C2PA manifests into iTXt chunks, editors add XMP as text chunks, and EXIF can live in eXIf. NoMoreAI removes these while preserving pixels and color.
PNG metadata locations
tEXt and zTXt hold simple key-value text; iTXt carries international text, including XMP (XML:com.adobe.xmp) and C2PA (c2pa keyword); eXIf holds EXIF data.
What's preserved
IHDR, PLTE, IDAT, IEND and color-critical chunks (gAMA, sRGB, iCCP, pHYs, tRNS) are kept, so appearance and transparency are unchanged.
Lossless by design
Chunks are dropped without touching pixel data — PNG cleaning is always lossless in NoMoreAI.
Batch PNG cleanup
Use bulk mode to strip metadata from many PNG files at once and download them as a ZIP.
Frequently asked questions
What metadata is stored in a PNG?
Text chunks (tEXt, zTXt, iTXt) can hold titles, comments, XMP and C2PA; the eXIf chunk holds EXIF; and other ancillary chunks can carry color or gamma information.
Where does C2PA hide in a PNG?
In an iTXt chunk whose keyword is c2pa, containing a JUMBF manifest.
Does PNG cleaning lose transparency?
No. Transparency (tRNS and the alpha channel in image data) is preserved.
Does it change colors or quality?
No. Color-critical chunks such as iCCP, sRGB and gAMA are kept, and pixel data is untouched, so the PNG is lossless.
Does it also remove EXIF and eXIf from PNG?
Yes — the eXIf chunk is removed along with text chunks.
Can I keep some text chunks?
The current version removes all metadata text chunks. Selective keep-lists are a planned PRO feature.
Can I clean many PNGs at once?
Yes — drop several files in Bulk cleanup and download one ZIP.
Is it free and private?
Free, no account, and fully local — your PNGs are never uploaded.
