Siliph vs PDF24:
Browser-Native vs Desktop-Only
PDF24 is a capable Windows desktop app, but its web version is an afterthought. Siliph is browser-first — works everywhere, no installs, free AI.
Works on Any Device
PDF24 requires Windows. Mac, Linux, Chromebook, iPad users get a stripped-down web version. Siliph is identical on every platform — full feature set in any browser.
Zero Installations
PDF24 pushes .exe downloads. Siliph runs instantly — no admin rights, no IT approval, no disk space. Works on locked-down corporate machines and school Chromebooks.
AI Document Assistant
PDF24 has zero AI. Siliph includes free AI chat, summaries, and Q&A built into every tool. Upload a contract, ask questions, get cited answers.

The desktop trap
PDF24's model: download the Windows app for full features. But what if you're on a MacBook? A Chromebook? An iPad? A locked-down corporate laptop without admin rights? You get the "web version" — a shadow of the desktop app.
Siliph was built for the browser from day one. Every tool — merge, split, compress, OCR, AI chat — runs at full fidelity in Chrome, Firefox, Safari, Edge. No feature gap between platforms. No "pro version" locked behind an .exe.
AI that PDF24 doesn't have
PDF24 is a format manipulator. It moves pages, compresses bytes, converts formats. It doesn't understand what's inside. Siliph's AI Document Assistant reads your PDF: "Summarize the indemnity clause" → answer with page citations. "Extract all dates and amounts from this invoice" → structured list. Free, browser-native, no desktop required.
Built for India's exam portals
PDF24 has no SSC/IBPS/UPSC photo presets. Students on Windows use Paint; on Mac they're stuck. Siliph's Exam Photo Resizer works everywhere with one-click presets for 20+ Indian recruitment portals.
Your PDF tools should work on your device — not just Windows.
Browser-native, free AI, exam presets, zero installs. 50+ tools that work everywhere.
