PdfCompare

100% private, client-side PDF comparison & document suite

What it does

PdfCompare is an ultra-fast, 100% private PDF comparison & document utility suite that runs entirely in your browser memory via WebAssembly. Unlike traditional tools that upload sensitive NDAs, contracts, or tax data to remote cloud servers Key highlights: • Semantic word redline diff (find edited clauses & numbers) • Visual pixel canvas diff & curtain slider (spot moved stamps & logos) • Client-side IRS Form W-8BEN & W-9 filler • Text-to-PDF converter

PDF compare online free: spot every text change, clause edit, and layout shift side-by-side. 100% private, client-side WebAssembly diff in your browser.

Spot every change between two PDFs — words, clauses, images, and stamps. 100% private in your browser. Explore specialized differential workflows engineered for precision auditing and zero-risk compliance. Attorneys and corporate legal teams must review lengthy non-disclosure agreements, master services agreements, and vendor contracts. Manual line-by-line proofreading is dangerous because subtle additions—such as modifying confidentiality terms from 3 to 5 years or inflating liability caps—can easily be overlooked. Our PDF compare engine eliminates formatting noise and highlights exact textual revisions with legal-grade accuracy. Accountants, CFOs, and auditors face immense pressure when…from pdfcompare.app

    Hi HN, I have been working on a set of PDF tools that does all the processing directly in the web browser. From time to time I needed to do some simple PDF manipulations like merging PDF files. Sometimes the files contain my personal data and I was not comfortable using other online services where the file usually is uploaded to a remote server. Behind the scenes there is a small library written in C++ doing the changes to the PDF files. I am using the Emscripten compiler to compile it to WebAssembly that is running in the browser. It was a very good learning for me and it was easier than I…

  • I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
