LlamaPDF is a free online file converter with 50+ tools for PDFs, images, and documents.
The key difference: your files never leave your device. Every tool processes files directly in your browser using JavaScript — nothing is uploaded to any server. This makes LlamaPDF the safest option for confidential documents.

LlamaPDF's answer:
All file processing happens directly in your browser. Your files are never uploaded to any server, making it the safest option for confidential documents like contracts, tax returns, and medical records. It supports 93 languages — more than double any other file converter tool available.
LlamaPDF's answer:
Anyone who needs to work with PDFs or images but doesn't want to pay for Adobe Acrobat or upload sensitive files to unknown servers. This includes students, freelancers, small business owners, teachers, lawyers handling confidential documents, and international users who need tools in their own language.
LlamaPDF's answer:
I got tired of uploading confidential documents to random websites just to merge two PDFs. Every free tool required uploading files to their servers. I realized modern browsers are powerful enough to handle PDF manipulation, image conversion, and even OCR entirely in JavaScript — no server needed. So I built LlamaPDF as a privacy-first alternative where files never leave your device.
LlamaPDF's answer:
Next.js 16 (React framework), Tailwind CSS v4, pdf-lib for PDF operations, Tesseract.js for OCR text recognition, Canvas API for image processing, and Vercel for hosting. All file processing libraries run client-side in the browser — there is no backend server processing files.

LlamaPDF's answer:
Three reasons: privacy, price, and language support. Your files never leave your device — no server uploads means no data risk. Everything is completely free with no daily limits, no signup, and no feature restrictions. And with 93 languages, it works natively for users worldwide, from Icelandic to Yoruba to Khmer.

Event loops are a paradigm for processing events different than your typical single-threaded or multi-threaded application. Your request gets broken down into async "events" that are executed in a loop to improve performance and minimize synchronization across threads. It is famously used by Node.js as the backbone of their event processing and also by several other technologies like Redis and Nginx. - Source: dev.to / 18 days ago

TypeScript / Node.js: Excellent for building asynchronous backend systems that must stream text data smoothly to thousands of users simultaneously. - Source: dev.to / 4 months ago
Because Node.js operates on a single-threaded asynchronous runtime, it is inherently vulnerable to processes that hog the CPU for too long. I absolutely cringe whenever I see developers blindly copy-pasting complex regular expressions from StackOverflow without actually testing their performance impact. - Source: dev.to / 4 months ago
This tutorial walks you through setting up a simple Docker Compose project that serves two Node web servers over HTTPS using Caddy as a reverse proxy. You will learn how to use mkcert to generate wildcard certificates and the minimal configuration needed in the Caddyfile and docker-compose.yml to get it all working. - Source: dev.to / 5 months ago
