    Hi HN, Nick here. We're super excited to officially launch PDF.js Express [1]. PDF.js Express wraps a modern React UI around the PDF.js rendering engine to enable PDF annotation, form filling, and signing inside your web app. We've also made some improvements to PDF.js text search, and taken a different approach to how the viewer uses the PDF.js rendering API, resulting in sharp graphics at any zoom magnification [2]. Based on our research, more than 70% of those who try to implement these features on top of PDF.js find it too difficult or time-intensive [3]. For those who are successful,…

    I built EmbedPDF: an MIT-licensed, open-source PDF viewer that aims to match all of Adobe Acrobat’s paid features… for free. Already working: - Annotations (highlight, sticky notes, free text, ink) - True redaction (content actually removed) - Search, text selection, zoom, rotation - Runs fully in the browser, no server needed - Drop-in SDK for React, Vue, Preact, vanilla JS Why? Acrobat is heavy, closed, and pricey. I wanted something lightweight, hackable, and embeddable anywhere. Demo: https://app.embedpdf.com/ Website: https://www.embedpdf.com/ GitHub:…

    Hi HN, creator of EmbedPDF here. I recently posted my open-source PDF viewer here, and one thing I really value is that it runs completely offline. I started wondering if we could push that further: could we do full ML layout analysis (detecting tables, headers, columns) directly in the browser? To my surprise, it actually works. The catch: It is far from production-ready. It crashes on most phones, and on older computers, it can be incredibly slow. The why: I believe the future of document processing is local. Many users work with sensitive documents (bank statements, legal contracts) and…

    Hi HN! I've been working on SimplePDF to solve a problem I encounter weekly: filling out non-editable PDFs [1] --- # About SimplePDF - The documents you load, edit, fill never see the light of my server, everything is processed locally – no remote uploading anything. This includes the PDF generation. - There are no analytics / third party tracking your every move (I do collect usage data, but it's fully anonymous and processed and stored on my server): therefore no annoying cookie banner. You can read more on the Privacy Policy [2] - If someone before you has filled the same document,…

    I created this tool to make it quick and easy to sign PDF contracts, without having to deal with installing additional software and without worrying that my PDFs will get uploaded to a third party.
