Privacy, files and ads
Files are read with browser APIs and processed in your device memory. This page has no processing server: there is nowhere to upload your documents, images or audio.
You can check it: open the developer tools (F12), Network tab, and process a file. You will not see any request with your content.
All open-source libraries are served from this site. The only external download related to the tools is the OCR language model the first time you use it; that model does not include your document.
Advertising. ConvUp is free thanks to ads. They are served by Adsterra. In the European Union, the United Kingdom and Switzerland you are asked first; everywhere else they load straight away. They may use cookies or browser identifiers to show and measure advertising. They have no access to your files, which still never leave the device.
Audio is decoded and encoded with browser APIs and a local Web Worker. It is not sent to any conversion service.
