Built to the submission specs CoStar, LoopNet, Crexi and Ten-X actually enforce
Every CRE platform has its own acceptance gate and most boutique brokerages burn an afternoon re-exporting the same hero 12 different ways. CoStar rejects anything under 1200x800 and strips EXIF on upload; LoopNet Premium positions require a 1920x1080 hero with sRGB profile and caps the thumbnail at 640x480; Crexi's listing grid pulls a 1024x768 tile and a 2048x1536 lightbox source; Ten-X Commercial wants auction-ready 2048px long-edge TIFFs plus web-optimised JPEGs for the pre-bid teaser. Plotpane gives you one JPEG at quality 92 and about 2.4K — comfortably above every one of those floors — and the cropping to each platform's tile stays a manual step, because there is no per-platform export and no TIFF. The XMP enhancement disclosure is embedded in the file you download, so you can show a CoStar researcher or a Crexi broker-reviewer exactly what was edited, even though the platforms re-encode on upload and strip metadata as a matter of course. What it removes is the re-shoot and the retouch invoice, not the resizing.
