Stop Uploading Sensitive PDFs to Random Websites

Stop Uploading Sensitive PDFs to Random Websites Every time you upload a contract, medical record, or financial statement to a "free PDF tool" site, you're trusting a stranger's server with your most sensitive documents. Here's what actually happens on most free PDF sites: Your file uploads to their server It sits there (for how long? who knows) It gets processed, maybe logged, maybe backed up You hope they delete it Modern browsers can do everything a server can for PDF work: pdf.js extracts text from any PDF pdf-lib merges, splits, rotates, edits Tesseract.js does OCR on scanned pages Canvas API renders pages to images None of this needs a server. Your file never leaves your device. PdfWord (https://pdfwordtools.pages.dev) runs 47 PDF tools entirely in your browser: Merge, split, compress, convert, edit, sign 11 AI tools (summarizer, MCQ generator, chat with PDF, contract checker) Works offline as a PWA after first load The only exception: AI tools send extracted text (not your file) to the AI. Everything else is 100% local. Open DevTools → Network tab → upload a file → if you see your file in an upload request, it's going to their server. Check if it works offline (airplane mode) — if yes, it's truly client-side. Read the privacy policy — vague = red flag. If a free tool needs your file on their server to do something your browser can do alone, find another tool. Try it: https://pdfwordtools.pages.dev — disconnect your internet after loading, everything still works. 47 free PDF tools. No signup. No server uploads. Building in public.
