Hi Product Hunt! I'm Daniel, a software engineer based in Vienna. Every time I needed to merge or compress a PDF, I had to upload sensitive documents to some random server. Contracts, invoices, medical records — sent to who knows where. PDFUtils runs 100% in your browser using pdf-lib and pdf.js. Your files never leave your device. No uploads. No server processing. No accounts. What you can do: • Merge, split, compress, rotate PDFs • Add watermarks, page numbers, passwords • Convert between PDF and images • Extract text, rearrange pages, sign documents • View page thumbnails before making changes Available in 5 languages (EN, DE, ES, FR, PT). Works offline as a PWA. The privacy angle matters — especially for anyone handling legal, financial, or medical documents. Happy to hear your thoughts and what tools you'd want next!
