Unlike iLovePDF, Smallpdf, or Adobe's online tools, PDFMaster runs 100% in your browser using WebAssembly and pdf-lib — your files NEVER get uploaded to any server.
What makes it different:
• Zero upload = 100% privacy. Your PDFs stay on your device.
• No signup, no email, no account needed.
• No watermark, no file size limits, no daily caps.
• 11 tools in one place: Merge, Split, Compress, Edit, Rotate, Crop, Protect, PDF↔JPG, Word↔PDF, Excel→PDF.
• Works offline after first load.
