Hi Product Hunt 👋 Every online PDF tool I tried did the same thing: upload my file to a server, process it there, hand it back. Fine for a holiday itinerary. Not fine for a contract, a payslip, or a passport scan. So I built PDFMergely the opposite way. Instead of sending your file to the code, it sends the code to your browser. The PDF engine runs locally on your device, so there is literally no upload step — because there is nowhere to upload to. It's privacy by architecture, not by promise. A few things I'm proud of: - The whole site is locked down so file data has no network path to leave the page (strict CSP, no upload endpoint). - It works fully offline after the first visit. You can merge PDFs on a plane. - No account, no watermarks on your files, free. V1 ships merge, split, reorder, rotate, delete and extract pages, compress, watermark, page numbers, protect and unlock. More tools are coming. Honest tradeoff: because it runs on your device, very large files lean on your device memory and a phone is slower than a desktop. I think that's a fair price for your documents never leaving your hands. Would love your feedback — especially what tool to build next. Try it: https://pdfmergely.com
