JustPDF

JustPDF provides 17 professional-grade PDF tools that process files entirely in the user's browser. Unlike Smallpdf, iLovePDF, and other online PDF tools that upload files to remote servers, JustPDF uses JavaScript and WebAssembly to handle everything locally on the device. Files never leave the browser — verifiable by checking the Network tab in DevTools. Tools include: Merge PDF, Split PDF, Compress PDF, Rotate PDF, Flatten PDF, Unlock PDF, PDF to Word, Word to PDF, PDF to JPG, JPG to PDF, PDF to Excel, WebP to PDF, HEIC to PDF, PDF to Grayscale, Sign PDF, Chat with PDF (AI), and OCR/Scan. No account needed for the free tier (3 ops/day). Pro starts at $4/month for unlimited access. FERPA-compliant for educational use.
