ToolHub

Most online tool sites are an upload form with an ad break. Yours goes up, theirs comes back, and in between your document sat on a server you know nothing about. ToolHub does the work locally instead: PDF merging and splitting, image conversion, text and design utilities, calculators and marketing helpers, all executed client-side.

The interesting engineering is in the plumbing rather than in any single tool. One registry describes every tool; one generic runner renders it. Adding a tool is a data change, not a new page.

• 01Nothing is uploaded, so there is no storage, no retention policy and no breach surface.
• 02Per-tool, per-category and homepage Open Graph images are generated on demand rather than designed by hand.
• 03Every tool page carries 10–15 real questions, because that is how people actually search for these.
