Can remove metadata from PDF files, compress them, is open source and has next to no tracking (only usage report iirc)

Can't find the option to compress PDFs, I don't believe it has one.

Used it for years, unfortunately it's been progressively enshittified, culminating in what's now the only way to interact with it, through ChatGPT.

Software for the Tech-Savvy Power User [2/3]

Part 2 of 3 in Series: lists will continually be updated periodically. This is a continuation of my list, “Recommended Software for the Average Joe and Jane”, but with software I believe needs a bit more technical know-how. Criteria I look for universally for my lists are as follows: — Open source code: publicly audited — Privacy-focus: minimal data collection, encryption by default — Security-focus: 2FA available, encryption by default — Zero Knowledge end-to-end encryption (E2EE) when appropriate — Cross-platform or progressive web apps (PWAs) + cloud backup/sync — Freemium subscription model, so basic features are always available for free — Oligarchy / Big Tech alternative — Absence of “dark” or deceptive patterns Criteria specifically for this list: — Small organizations and up-and-coming software are welcome on this list — User experience may require more configuration, less convenience, and more tech literacy — Features available can replace or nearly replace Big Tech’s popular apps

phant's software list

my software list, mostly open-source.I have used the vast majority of the software listed there myself for a long time. This software list open-source/free/freemium apps for Windows 10/11 that I would recommend.This also includes tools for CS/EE background developer. This list is designed to highlight excellent software in a particular area, so you don’t need to install all the software on the list. You should only consider installing the software I’ve selected when you have a need that falls under a specific section of the list.
