Scientific tools with explanatory context.
The toolhub keeps educational documentation separate from interactive utilities. Each guide explains the workflow, assumptions, privacy boundary, and limitations before offering a launch link or repository link. Utility pages do not load AdSense code.
Read first, then launch
Every tool page includes substantial visible HTML content before an action link. This helps users decide whether a utility fits the task and keeps the interactive screen focused on the workflow rather than advertising.
Smart Image & PDF Compress
A local-first browser and Android workflow for image compression, PDF page extraction, and batch document conversion.
Read guide →XRD phase-analysis tools
A responsible starting point for cleaning, plotting, and reviewing diffraction data before phase identification.
Read guide →Band-gap estimation tools
A guide to reflectance data, transforms, fitting regions, and defensible reporting before calculation.
Read guide →Why utility routes are ad-free
Interactive utilities, forms, generators, loading screens, and error states are designed for a behavioral task rather than editorial reading. The toolhub therefore does not load Google AdSense code. Educational content remains visible and accessible on guide pages, while utility interfaces remain distraction-free.
