CompanyCam's model is volume: every photo and video lives in a Project, and the Magic Uploader pulls in up to 100 photos at a time — anything past that has to be selected manually. That is a lot of phone-camera weight moving over a crew's mobile data. Modern phone photos run 3-8MB each, so a hundred of them is half a gigabyte going up over LTE on the side of a building. Compression does not touch what CompanyCam is for — visual job documentation, before-and-after records, annotated markup — it just makes the transfer finish. What you want to preserve is legibility: a photo that still shows the flashing detail, the watermark line, the crack pattern. What you can throw away is pixels the app will never render and metadata you are not using. Skwish compresses and resizes in the browser, shows the before/after size per file, and gives you one ZIP instead of a hundred downloads. Note that CompanyCam's help center publishes no per-file size cap, only the 100-photo Magic Uploader ceiling, so the target here is transfer weight rather than a hard platform limit.
