# PNG framed selected-chunk removal

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

WHEN TO USE: Remove every PNG chunk of explicitly selected tEXt, zTXt, iTXt, eXIf or tIME types while retaining other bytes exactly. Checks CRC/framing and restricted static 8-bit RGB/RGBA headers only. Does not decode IDAT, guarantee valid images, sanitize all metadata, anonymize pixels or guarantee unchanged visual interpretation; EXIF removal may change orientation.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Need bounded chunk-type removal under a container-framing-only guarantee

## Outside this profile
- Complete metadata scrubbing, privacy sanitization, anonymization, valid-image certification or guaranteed visual equivalence
- JPEG, WebP, HEIC, TIFF, palettes, transparency keys, APNG, interlacing or unsupported PNG headers
- Decoding pixels, validating compressed image data, decompressing embedded text or parsing EXIF/ICC semantics
- Extracting archives, writing files, uploading, publishing, or changing external state

Proposed nominal USD 0.005 per successful call; payer fees excluded. No verified runtime availability.
