Cleaning Metadata Without Altering Image

I clicked Remove All Metadata, but when I Save the file, it is much larger in size so XnView must be reproccessing the image. How can I strip the metadata without altering the image?

in browser, use clean metadata. 'Save' recompress the image

Using Clean Metadata from the browser doesn't recompress the image? In a hex editor the cleaned file looks different from the original. I was expecting only the beginning of the file where the metadata is to be different.

Did you activate Optimize (Huffman table)?

No! The huffman table optimization is a lossless (reversible) process that has absolutely no effect on the resulting image quality. If one has the option, it is almost always best to enable JPEG optimization. The extra file size savings can't hurt. However, as it may potentially reduce compatibility with some bad JPEG decoders, this may be enough of a reason for you to disable it.

The only item activated is EXIF. Everything else is unselected.

Bug confirmed

I used FujiFilm FinePixS1Pro (1).jpg and CompareIt! (Find moved sections & Align mode activated) for my tests.

when you use 'Clean metadata' in browser mode?

Yes, in the browser. (cmd_CleanMetadata isn't available in view mode, I believe.)
