BreezePDF lets you edit, sign, merge, compress, redact, OCR, fill forms, extract tables, and use 30+ more PDF tools — all in the browser, no sign-up. Files never leave your computer. I built it because when people search Google for common PDF tasks, many of the tools they find upload documents to a server. I wanted an option that keeps files local instead. I posted an earlier version on HN last spring: https://news.ycombinator.com/item?id=43880962 At the time it only supported a small set of features. Over the last 10 months I rebuilt large parts of it and expanded it to…

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, Arek here. We’re super excited to officially launch PSPDFKit API [1]. PSPDFKit API is a collection of HTTP APIs that enable you to convert, generate, and edit documents without running any service on your infrastructure. What differentiates our API from others is that you can chain together multiple “actions” as part of a single API request. For example, you can convert, OCR, watermark, edit, and flatten a document — all in one call. Available actions [2]: - PDF Generator - PDF Converter - Image Converter - OCR - Watermark - Merge - Split - Duplicate - Delete - Flatten Our…

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,…

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…

Hello HN! It kept surprising me how much of a hassle it is to generate a PDF with decent HTML5 rendering from my SaaS apps. I tried several free libs and APIs but ended up with botched rendering a lot of times. So I set out to simplify this chore by creating an AWS hosted HTML to PDF conversion API that's based on Chrome. This API will allow a dev to just send the HTML to our API and get a PDF in response without having to worry about running and managing Chrome somewhere in their infra. I just finished the first version of my landing page and hosted pdf generation API…

PodPDF▲7I'm a backend, infra dev for a IoT based European startup for few years. After years of ups and downs with distributed computing ideas and being amazed by it, I badly needed a side project to exercise them on my own. For one, this is more of a exploration in that direction, but I also want to see if PDF API SaaS business still has legs.
