Is there a free tool that will allow me to convert files to PDF in batches? I have found all of the free online software to be very slow and inconvenient.
It is definitely understandable that free online tools might not be working out for you. Most of those are fairly low quality, and are not designed for professional users. I would not recommend most of them for users who need batch conversion. If you want to try a free conversion tool that is far more advanced and reliable, check out CVISION’s PdfCompressor. This tool can convert files to PDF in addition to compressing them, and you can download the trial version for free without making any purchases.
