What it does
Most PDF tools hide the best features behind paywalls or daily limits. I built pdfhub.tech to be different. It’s a 100% free 'utility hub' that combines high-performance PDF tools (merge, compress, edit) with a specialized LaTeX editor for students and devs. No watermarks, no ads, and no limits. Built by a backend engineer and Phd Student for speed and privacy, it’s designed to help you when you need it. Whenever you need, you can find it, honest hub you can trust.
Free PDF & LaTeX tools for students and educators. Edit, merge, split, compress, sign and protect PDFs. No signup required, no paywalls — completely free.
Free online PDF and LaTeX tools for students, educators, and professionals. No registration required. No credit card needed. Get one free download every 24 hours.

Write and compile LaTeX documents directly in your browser, with support for mathematical equations, academic formatting, tables, and instant PDF preview. No installation or local setup required — just open the editor and start writing. Pdfhub is completely free to use. Every user receives one free download every 24 hours with no subscription or credit card required. The platform is fast, secure, and works on any device with a modern web browser.…from pdfhub.tech

No signup, no watermark. Why: I was frustrated that many “free” PDF tools require uploads, add watermarks, or force accounts. I wanted a simple tool where files stay on-device by default. What it includes: - Edit & annotate: type on PDF, highlight, draw/markup, add notes - Add images/branding: insert images/photos, add a logo to a PDF - Organize: merge, split, extract pages, delete pages - Compression: compress for email/WhatsApp/portal…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
