Built a pitch deck tool for my own use

I was raising money for a second venture and was tired of paying $65 a month to docsend for limited features, like no watermarking. So I went out to build one for my own use focusing on the few features I wanted. Deckviewer.com allows users to upload common pitch deck file types like pdf, pptx, docx and converts them into a jpg slideshow accessible with a link and password. Users can update their deck, and also see basic stats, like when a deck was opened, and also page view stats. The free tier allows you to try it out with one deck and a few recipients. I've also kept detailed analytics turned-on for the free-tier. Let me know how I can improve this, comments etc! Hopefully somebody finds this useful too.
