About PDFDrawer
PDFDrawer is a drawer full of free file tools — the kind you reach for a few times a month and never want to install software or open an account for: merge this, split that, shrink it, sign it, turn it into a document. It is built and maintained by the small team behind a family of free tool sites, and it follows one rule the others in the drawer will recognize: the tools work where your files already are — on your device.
Nothing is uploaded. Ever.
Every PDFDrawer tool runs as code inside your browser. When you merge a contract or sign a form, the file is read by your own machine, processed in your tab, and downloaded back to you. There is no upload endpoint to send it to. That is a deliberate architectural choice, not a policy promise — the tools keep working in flight mode, and there is simply no server copy of your document to secure, retain or lose.
How the tools are built
The drawer is built from respected open-source engines, all running locally: pdf-lib for page surgery, pdf.js (Mozilla's renderer) for reading and rendering, jsPDF for building PDFs from images, the docx library for Word files, heic2any for iPhone photos, and qpdf — the professional PDF toolkit, compiled to WebAssembly — for removing restrictions. Each tool page explains honestly what its engine does and doesn't do, including the limits (a compressed PDF's text is no longer selectable; a converted Word file simplifies complex layouts).
The family
PDFDrawer is one of eight free sites we run: CalcVitals (health calculators), CalcPrincipal (finance calculators), CalcCoverage (DIY calculators), CalcWhen (everyday tools), CalcPairs (unit converters), AllPetBreeds (pet breed profiles) and Cálculos Fáciles (calculators in Spanish). They all share the same religion: free, fast, no sign-up, and your data stays yours.
