Privacy
How this website handles selected files, browser preferences and service requests.
Updated: 22 September 2026
Selected files and conversion results
The conversion tools read selected files in your browser and process them with browser code and local workers. The application does not send these files or QR contents to a conversion API. Results use temporary browser objects and download links; there is no account-based file history or server retrieval feature. Download results before leaving the page.
Browser storage
Changing the language saves paper-switch-language in localStorage. Clearing this site’s browser data removes that preference. The application does not save selected document contents to localStorage or an application file database. Browser caches and files you download are controlled separately by your browser and device.
Hosting and network requests
Cloudflare serves the site, scripts, fonts and conversion resources. Requests to load them include connection information such as your IP address and browser headers. Local conversion does not mean browsing the website is anonymous or offline. Hosting logs and their retention are controlled by the hosting service and its configuration; this page does not promise a fixed deletion period.
Advertising cookies and third parties
This site loads Google advertising code. Google and other advertising providers may use cookies or identifiers to serve and measure ads, including personalization based on visits to this and other websites. Their processing is separate from the local conversion tools. You can manage personalization in Google My Ad Center and review Google’s partner-site information using the links below. Browser cookie settings may also restrict storage.
Email and privacy requests
Contact links open your email application; there is no contact form on this site. Sending an email shares your address, message and any attachments with the operator’s Gmail mailbox and email providers. Send only information needed for your question. For access or deletion requests about correspondence, email the same address; do not send confidential source files.
