Siliph vs PDFsam:
Browser-Native vs Desktop-Only
PDFsam is a respected open-source desktop tool, but it requires Java, installs, and only runs on computers. Siliph is browser-first — works on phone, tablet, Chromebook, any OS — with free AI built in.
Works Everywhere
PDFsam is Java desktop-only. No ChromeOS, no iPad, no phone, no locked-down corporate laptop without admin. Siliph runs in any browser — Chrome, Firefox, Safari, Edge — on any device, instantly.
Zero Installation
PDFsam needs Java runtime + app install. On managed machines, that means IT tickets. Siliph: open tab, drop file, done. No .exe, no .dmg, no .jar, no updates to manage.
Free AI Assistant
PDFsam is a pure split/merge/rotate tool. No OCR, no AI, no content understanding. Siliph adds free AI Document Assistant — summarize, chat, extract data from any PDF.

The Java problem
PDFsam is well-built for what it is — a desktop split/merge tool. But the Java dependency is a real blocker: many corporate environments block Java, ChromeOS doesn't support it, iPads can't run it, and keeping Java updated is a security chore. Siliph sidesteps all of this with WebAssembly-powered tools that run natively in the browser sandbox.
More than split/merge
PDFsam does split and merge well. But if you need OCR, compression, conversion, Bates numbering, exam photo resizing, or AI summaries — you need another tool. Siliph unifies 50+ tools in one place: split, merge, OCR, compress, convert, sign, protect, organize, AI chat — all free, all in-browser.
Built for India's exam workflows
PDFsam has no concept of SSC/IBPS/UPSC photo specs. Students on Mac or Chromebook can't use PDFsam at all. 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 your desktop.
Browser-native, free AI, exam presets, zero installs. 50+ tools that work everywhere.
