exif

Use exif to inspect and remove EXIF metadata without decoding or re-encoding image pixels.

import "std:exif"

API reference

Method	Returns	Notes
exif.has(data: any)	boolean	Reports EXIF data in raw TIFF or EXIF blocks and in JPEG, PNG, or WebP containers.
exif.orientation(data: any)	number	Returns the EXIF orientation from 1 through 8. Missing or invalid metadata returns 1.
exif.strip(data: any)	byte[]?	Removes EXIF segments or chunks from JPEG, PNG, and WebP data.

data may be a string, byte[], or an array of byte values. Unsupported input returns null. Malformed and unsupported image containers are returned unchanged. Raw TIFF data can be inspected, but cannot be stripped without rewriting the TIFF image and is therefore returned unchanged.

JPEG stripping removes only APP1 segments with the Exif signature, so XMP APP1 data is preserved. PNG stripping removes eXIf chunks. WebP stripping removes EXIF chunks, clears the EXIF feature flag, and updates the RIFF container size.
