PDF Tools by Renderlog

What it does

All the PDF tools you actually need — merge, split, compress, OCR scanned PDFs into searchable text, sign, unlock, and convert to Word — running entirely in your browser via pdf.js and WebAssembly. Files never touch a server. No signup, no ads, no upload limits, works offline after first load. Free forever. Built for anyone who's ever hesitated to upload a contract, ID scan, or salary slip to a "free" tool that quietly stores your files on someone else's machine.

  I built a frontpage for personal blogs▲783

  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.
