At PDFStudio, your privacy is built directly into our architecture. All PDF and image operations—including editing text, compressing, merging, splitting, signing, scanning, rotating, converting, and sanitizing metadata—run 100% locally inside your web browser using WebAssembly and HTML5 Canvas.
Your files are never uploaded, transmitted, or stored on our servers or any third-party cloud storage. Once you close or refresh your browser tab, your files are immediately cleared from your device's local memory.
We do not require account registration, and we do not collect personal names, passwords, or document contents. We use standard browser localStorage solely to remember your interface preferences, such as your selected language (EN, FR, ES, RU, AR) and theme mode (Light or Dark).
To keep PDFStudio 100% free for everyone without watermarks or file limits, we may display advertisements provided by third-party ad networks, including Google AdSense:
