Why does PDFy exist? I got sick of documents getting locked up behind login walls of services like Scribd. PDFy exists to offer a place where anybody can instantly upload and share a PDF, much like Imgur does for images. PDFy is free, ad-free, and non-commercial.
Uploads are disabled for a few more days as the work on a new CDN is finalized. More information can be found in this blog post.
You can still upload documents by e-mail! Send your documents to firstname.lastname@example.org - they are processed roughly once a day.
