Why FilePrepKit
Most file conversion sites are built to handle anything, for anyone — which usually means they handle nothing particularly well for people doing this specific kind of work. FilePrepKit is built the other way around: every tool exists because it solves a specific, recurring problem for people who cut, engrave, or sell digital files, not because it's a generic feature.
That focus shows up in small ways: a checker that specifically looks for the kind of open paths that ruin a laser cut, a photo tool built around dithering instead of generic filters, a watermark tool designed around what actually protects an Etsy preview rather than a decorative stamp. None of it is trying to be an all-purpose design suite.
It's also built around a simple privacy principle: your files are processed directly in your browser and never uploaded to a server. That's not a marketing claim — it's a direct consequence of how the tools are built, and it means your unreleased designs, client files, or unlisted products stay on your device the entire time.
