PDF Board makes it simple and easy to view and organize your PDF reports. Stop using email and storage platform tools for sharing and viewing your PDF reports. With email, you have to tap or click on one report at a time. And storage app viewers, they are no better. None of them were designed for simple viewing. PDF Board allows you to create "boards" of your PDFs to group them together. When you're ready to view them, simply pick a board to view and then swipe them right and left to switch between them. You can create a board manually or we have a simple form to add your URL and name your board and easily generate a QR code for sharing. We recommend using one URL and naming the PDFs for the board 1.pdf - 9.pdf. That is the most simple design, but we allow you to enter 9 unique URL and file names if you like. Either way, you can generate a QR code to email and/or text for sharing your board with others. Do you ever email your boss or co-worker a PDF or group of PDFs and they struggle with viewing them? What if you could simply have your boss or co-worker open an app and tell them what board to view? Those of you who look at your financials every day, like those generated via accounting systems, what if you could have them available at the tap of an app? It's really that easy. Once you start using PDF Board, you'll wonder why something this easy wasn't created long ago. One final note, you can use any report automation tool to upload your reports to your server. PDF Board works with any PDF stored anywhere, as long as it's available via a URL.
