Thanks to your detailed description I can reproduce the problem.

This problem is supposed to be fixed in XnView MP 1.5.0 beta. Please check and confirm the bug fix here.

1.5.0 well.. it cleans GPS, however:
- metadata is not affected until image is saved (that is not acceptable for non-loseless formats), also
- image become dirty once OK pressed in dialog

it shall work EXACTLY the same way it works in Browser
it always shall Write, not Apply because this is delete action on existing metadata
(not the case when we have image in buffer+new metadata that can be saved in new format)

I disagree, 'clean metadata' works not only on jpeg but on image datas

[user0]

what "image datas" you mean, file timestamp?
why Viewer's Clean metadata is different from Browser's?

my usecase - I would like to delete all metadata from image (eg jpeg, png, gif, webp) from any place of the app (viewer, browser, batch).
While doing it I would like to keep image data untouched (unresampled/unconverted/etc).
Currently I cannot do it from Viewer as it forces me to manually resave file after cleaning (not saying that it does not clean all metadata), that triggers image resampling for default lossy settings of some formats.

this is how I see it )
where am I wrong?

It's like 'Edit IPTC/XMP', you change the metadata of loaded picture, not the file.

[user0]

than it shall have the same Write and Apply buttons as Viewer's 'Edit IPTC/XMP'.

hm.. I just noticed that Write in 'Edit IPTC/XMP' makes file dirty.
Imho, it should not, because it pointless nd confusing - if you press "Don't save" new metadata will not gone anyway, its already written into the file.

I can't reproduce, do you have a way?
