strip_image_meta_data removes EXIF, XMP, and other metadata from images. This includes camera information, GPS coordinates, thumbnails, and editing history.

When to use it

In CoreFilters, the default RewriteLevel: it runs unless you disable it.
Part of OptimizeForBandwidth, the level that optimizes resources without changing their URLs.
Also switched on by recompress_images and rewrite_images.
Risk rating on these docs: Generally safe.

Risks

Stripping color profiles can cause subtle color shifts on wide-gamut displays or for images authored in non-sRGB color spaces. This affects a small fraction of web images.
Stripping metadata removes copyright and attribution information embedded in the file. The metadata is removed from the served variant only; original files on disk are not modified.

Configuration

Enable it in the module configuration, at server, virtual-host or location scope:

Apache

ModPagespeedEnableFilters strip_image_meta_data

nginx

pagespeed EnableFilters strip_image_meta_data;

IIS (pagespeed.config)

pagespeed EnableFilters strip_image_meta_data

It is on by default under CoreFilters; to turn it off:

ModPagespeedDisableFilters strip_image_meta_data   # Apache
pagespeed DisableFilters strip_image_meta_data;   # nginx
pagespeed DisableFilters strip_image_meta_data   # IIS

On the worker

The worker runs its own pipeline, configured by flags. Its equivalent of this filter is the image pipeline transform. Always-on baseline under pagespeed on;; there is no per-transform off switch.
