What could have caused my photo to get resized?

When I texted a photo to my email, the attachment size was always 238 KB.

Recently I tried texting the same photo to my email, and the attachment size was 287 KB.

Short of paranormal activity, what could have caused this change? Does this mean my photo is corrupt?

I would appreciate any help.

Before anyone asks, I don't use iCloud Photos and never have.

Did you send the photo in a different format? Raw and JPEG, for instance, would have different file sizes.

Duplicates sometimes have modified metadata, which may account for size differences.
