PDFMergely – In-browser PDF tools that never upload your files
In plain words
PDFMergely is an in-browser PDF tool that processes files locally without uploading them to external servers. It allows users to merge, split, and manipulate PDF documents directly in their web browser. The service is designed for anyone who needs to edit PDFs while keeping their files private. The key feature is that all processing happens on the user's device, ensuring documents never leave their computer.

Hi HN! I built PDFly — a PDF toolkit that runs entirely client-side. No file uploads, no server processing, no account needed.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums.

Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
