There should be a free PDF editor for bookmarks without ads, freemium or a subscription. I looked but never could find one. Just a few python command line ones that work great for advanced users. This app is all local. No cdn (content delivery networks) either just 5 files loaded ~4MB total (index.html 120KB, pdf.worker.min.js 1.1MB, pdf-lib.min.js 525KB, pdf.min.js 320KB, index.min.js 19KB)
For annotation, adding text, highlighting, adding a signature just open PDF in Firefox / Librewolf.
Doesn't do vertical position (jumping to exact location of text in a page) within PDFs (as that requires pymupdf and python) but allows one to easily modify bookmarks for pages. Crop function isn't practical in this app.
Click Compress icon, to copy to terminal, open terminal where pdf is located then paste command to compress PDF Use Ghostscript (free AGPL) for PDF compression: Windows
