About ToolVault

ToolVault is a collection of free, privacy-first online tools designed for everyday tasks — image compression, PDF merging, calculations, QR codes, and more.

Our Mission

We believe the best tool is the one you can use without friction. No signup. No watermarks. No paywalls. No file uploads to unknown servers. Every tool on ToolVault runs entirely in your browser, meaning your data stays on your device.

Why Browser-Based?

Uploading sensitive documents — passport photos, financial spreadsheets, personal images — to a third-party server carries inherent privacy and security risks. By running tools entirely in your browser, we eliminate those risks entirely. What you process here stays here.

Technology

ToolVault is built with Next.js, TypeScript, and Tailwind CSS. Individual tools use best-in-class open-source libraries: browser-image-compression, pdf-lib, qrcode, date-fns, and more. Heavy libraries are lazy-loaded so you only pay the cost for tools you actually use.
