You now have a highly compressed Photoshop file that fits 100MB and looks sharp on a 4K monitor.
To understand why a 100MB download is suspicious, we need to look at the software itself. Adobe Photoshop is a behemoth. It contains thousands of DLL files, brushes, fonts, plugins, and core executables.
When you save, a "Photoshop Format Options" box appears. Unchecking will stop Photoshop from saving that extra flattened composite image. This makes the file much smaller, though it might not open correctly in older versions or apps like Lightroom. 5. File Formats to Consider
Sometimes, these files are actually very old versions of Photoshop (like CS2 or CS6) disguised as modern software. While older versions are indeed smaller, they lack the AI-powered features (like Neural Filters and Generative Fill) that users expect today.
