File formats
PDFs open directly. Other documents are converted locally for viewing.
Conversion varies with the file. Complex layouts, fonts, and embedded objects may differ from the original editor. Installed Office or LibreOffice may improve results.
Local documents are rendered and converted on your PC. No sign-in. No remote document conversion service.
Webpage capture contacts the website. Updates contact GitHub. Text recognition may download its runtime and language data on first use, then runs locally. Login pages or bot checks may interrupt a capture.
