Every major flipbook service starts with an upload to their cloud. Riffle is the exception: the whole conversion runs in your browser, so your document never leaves the machine.
Make yours freeRiffle's converter is the page itself, powered by pdf.js. There is no upload endpoint, no processing queue, no stored copy - the architecture cannot leak what it never receives.
Legal drafts, HR handbooks, financials, client work under NDA, photos of your kids. If uploading it feels wrong, this is the tool built for that feeling.
Open your browser's network tab while you build. You will see the page load once and nothing leave. The privacy claim is inspectable, not a promise.
Modern browsers run pdf.js, the same PDF engine Firefox uses, entirely on your machine. Riffle renders pages locally and assembles the flipbook file in memory.
The output is a file on your device. Share it or host it - that choice, and the copy itself, are entirely yours.
Once the maker page is loaded, the build itself needs no network. The finished flipbook opens fully offline.
Free 3-page builds. No account. Nothing to install, nothing uploaded.
