Your files never leave your machine, and nothing is uploaded to a server.Drop in your PDFs, pick the steps you need, and download one finished, protected document.It works on any PDF, whatever you designed it in. If you make your resources in Canva, Google Slides, or Keynote, export a PDF as usual and finish it here. You no longer need to work in PowerPoint to flatten and secure your files.What it does Merge multiple PDFs into one document, reordered as you like Assemble pages in a thumbnail grid: drag to reorder, rotate, or remove individual pages Watermark with your own text or a logo, positioned in a corner, in the center, or tiled across the page. It goes on before flatten, so if you flatten too, the mark bakes into the page and can't be lifted back off Add an invisible marker: a hidden phrase, like an order code or buyer name, that doesn't show on the page but can be searched for later. It survives flattening, so a leaked copy can be traced back to the buyer you sent it to Flatten pages into pixel-perfect images so your work is harder to edit or extract. Hyperlinks still stay clickable Compress with smart per-page encoding to keep files small for upload limits Encrypt with AES: set owner permissions (printing, copying, editing, annotating) and an optional open password Also accepts PowerPoint (.pptx) files as input Private by designEverything runs in your browser.
