Everything you need to know about Private Document Tools
Yes, absolutely. All document processing happens entirely in your browser using JavaScript. Your files never leave your device, are never uploaded to any server, and are never stored anywhere except temporarily in your browser's memory during conversion. Once you close or refresh the page, everything is cleared.
No installation required. Private Document Tools works directly in your web browser. Simply visit the site and start converting your documents. We recommend using modern browsers like Chrome, Firefox, Safari, or Edge for the best experience.
Since processing happens in your browser, the main limitation is your device's available memory. Most modern devices can easily handle documents up to 50-100 MB. Very large files may take longer to process or may require a device with more RAM.
We currently support conversions between Word (DOCX), Excel (XLSX), PDF, CSV, JSON, XML, Markdown, and HTML formats. Each tool is optimized for specific conversion types. Check the individual tool pages for detailed format specifications.
Once the page is loaded, many conversions will work offline. However, the initial page load requires an internet connection to download the necessary JavaScript libraries. Some tools may require additional resources that need internet access.
Yes, Private Document Tools is completely free to use. There are no premium tiers, subscriptions, or hidden costs. We believe privacy should be accessible to everyone.
Yes, you can use Private Document Tools for both personal and commercial purposes. Since everything runs in your browser and nothing is uploaded to our servers, you can convert any documents you have the right to process.
Browser-based processing has some inherent limitations compared to server-side processing. For example, complex Word documents with advanced formatting may not convert perfectly to PDF. We're continuously improving our tools, but we prioritize privacy over feature completeness.
