PdfCompare
100% private, client-side PDF comparison & document suite
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
Hey Product Hunt! 👋 I'm excited to share PdfCompare with you today!
Like many of you, I constantly review contracts, financial statements, and technical specs. But I ran into two big frustrations with existing solutions:
1. Enterprise PDF tools charge $239+/year just to compare two versions.
2. Free online diff checkers upload your confidential PDFs to their remote cloud servers—a massive compliance and data breach nightmare for NDAs and client files.
So we built PdfCompare: an open-standard, zero-cloud PDF workbench powered 100% by client-side WebAssembly.
What makes it different:
🔒 Zero-Cloud Guarantee: Your documents never leave your browser RAM. Close the tab, and the data vanishes instantly.
⚡ Precision Diff Engines: Word-level text redlines (tracking edited terms & numbers) + visual pixel overlay with a split-curtain slider (catching moved signatures and CAD drawing shifts).
📑 Extra Built-in Utilities: A client-side IRS tax form wizard (Form W-8BEN & W-9) and a clean text/code-to-PDF generator.
🚫 No accounts, no subscriptions, no page caps, and no branding watermarks.
We'd love to hear your thoughts, feedback, and feature requests. What document tools should we build next?
Thank you for checking it out! 🚀
