A punch list is the worst-case photo set: many small items, each needing two or three frames, all of which have to reach a contractor, a client and often a lawyer-proof archive. Forty items at three photos each is 120 files, and at phone-camera weights that is a package nobody can email and a portal upload that takes all afternoon. The requirement here is not beauty, it is completeness and identifiability: each photo has to clearly show the specific defect, in the specific room, for the specific item on the list. That means a hard downscale to thumbnail size is the wrong move — it destroys the evidence — while stripping megapixels the reviewer never zooms into is the right one. The other thing worth keeping is the naming and ordering, which is why a ZIP of compressed files is more useful than a folder of renamed images. Skwish compresses a batch in the browser, shows before and after per file, and packs the whole set into one ZIP; EXIF removal is a separate choice so you do not silently lose capture dates on closeout records.
