We built NoStorePDF with a strict local-first architecture. It is the definitive privacy-first alternative to iLovePDF, Smallpdf, PDF24, and Adobe Acrobat Online. No hidden servers, no cloud storage, no compromised privacy.
Unlike traditional PDF editors, your files are never uploaded to any remote server. Every single byte remains on your computer throughout the entire process.
We have no databases storing your sensitive documents. Once you close your browser tab, all temporary local processing data is completely erased.
Powered by next-generation WebAssembly (WASM), we bring enterprise-grade processing logic directly into your browser for instant, secure execution.
Add custom text to PDF files online for free. Insert text anywhere, customize fonts, colors, and positions with secure browser-based processing.
Apply approved, confidential, draft, or custom text and image stamps to your PDF documents. Add professional watermarks and stamps securely in your web browser.
Whether you need to fill out a non-interactive PDF form, insert a "CONFIDENTIAL" watermark, or add legal annotations to specific pages, adding text to a PDF is a fundamental requirement. However, using traditional online PDF editors exposes your documents to major security risks, as they force you to upload your files to their remote servers to process the text overlay. NoStorePDF's Add Text to PDF tool completely eliminates this risk by utilizing a 100% Browser-Based Processing engine.
With NoStorePDF, your files never leave your device. Our advanced text layer manager runs directly in your local browser memory. You can insert unlimited text blocks, customize fonts and colors, snap text to smart alignment guides, and render the final document instantly—all while guaranteeing absolute data privacy.
{date}, {time}, or Page {page} of {total} across multiple pages.Editing sensitive invoices, medical records, or legal contracts requires uncompromising security. Cloud-based PDF editors fundamentally compromise that security. NoStorePDF was built differently.
