Possible disadvantages of Zamzar

  • Impossible to convert from EPUB to PDF
    I convert EPUBs to PDFs often with Zamar @ zamzar.com. You are limited to 2 or 3 free conversions per day. When you get to the site, note that "Convert to" format is found by having to scroll down a lot in column 2 under Document formats, which is below image types at the top of column. I have never checked for safety but I have been using this site for years. Note there's also a file size limit on conversions.... Source: over 3 years ago
