Hi Product Hunt! 👋 I'm Jair, the maker of easyPDF. In Brazil, a huge amount of paperwork still runs on PDFs that need to be legally signed: contracts, accounting reports, public procurement bids, city hall processes. To sign them with legal validity you need an ICP-Brasil digital certificate (often a USB token), and to prepare them you usually juggle three or four different tools: one to merge, another to compress, another to convert, and a separate (and expensive) e-signature service. I work with documents every day and got tired of that, so I built easyPDF: one place where you can merge, split, compress, convert, OCR and translate PDFs, and then sign them with your ICP-Brasil certificate (A1 file, A3 token or cloud A4), with a timestamp and a QR code anyone can use to verify the signature. Things I'm most proud of: • Send for signature by email: the other person signs on their phone, without creating an account. • Batch signing: sign 50 PDFs with a single PIN entry. • A free desktop app for Windows and Linux that works offline and signs with A3 tokens — the PIN never leaves your computer. • LGPD-compliant redaction that actually removes the text under the black boxes. • A REST API and an MCP connector, so ChatGPT and Claude can merge, compress or send contracts for signature right from the chat. The interface is in Brazilian Portuguese because the core feature (ICP-Brasil signatures) is specific to Brazil, but the PDF tools work for anyone. You can start free, no credit card, and try Pro for 7 days. I'd love your feedback — especially on what would make you switch from the PDF tools you use today. Thanks for checking it out! 🙏
