About In-Browser PDF Processing
Portable Document Format (PDF) files are the universal standard for sharing contracts, medical records, invoices, and academic papers. However, traditional online tools force users to upload their most sensitive documents to unknown third-party cloud infrastructure.
Toolnova changes this by bringing high-performance WebAssembly engines directly into your web browser. You get lightning-fast document merging, splitting, image-to-PDF conversion, and compression without sacrificing confidentiality or waiting in cloud processing queues.
PDF Tools FAQ
Common questions about usage, privacy, limits, and browser compatibility.
Are PDF files uploaded to any server when processed?
Never. Toolnova processes all PDF documents locally in your browser memory via WebAssembly and pdf-lib. No files are ever uploaded or transmitted across the network.
Is there a page count or file size restriction?
Because files are handled directly by your computer or smartphone hardware, there are no artificial limits. Most modern devices easily handle documents exceeding 100 pages or 50MB.
Will my hyperlinks, forms, and bookmarks be preserved?
Yes, our merging and splitting tools combine underlying PDF object streams losslessly, maintaining original vector definitions and metadata.
