We built Flipp because the standard online PDF tools were fundamentally broken. When you needed to merge PDF files containing sensitive business contracts, or split PDF documents with personal medical records, traditional services asked you to compromise. They required you to upload your private files to distant servers, putting your data at risk while you waited in artificial queues, often to be met with a paywall or an account creation screen.
We envisioned a better way. Flipp exists to provide a privacy-first online PDF toolkit that never compromises on security, speed, or accessibility. Our core belief is simple: your documents belong to you, and they should never leave your device.
What we actually prioritize: we don't collect files, we don't collect metadata about the files you process, and we don't sell or share anything — because there's nothing on our servers to sell in the first place.
How Client-Side PDF Processing Works
Flipp is a true browser PDF editor. When you use Flipp to compress PDF files or convert documents, the entire operation happens locally within your web browser.
We don't have servers that process your files. We don't have databases storing your documents. Instead, Flipp downloads the necessary processing logic to your device when you load the page. Your computer's processor does all the work directly in the browser memory. Once you refresh or close the tab, the data is gone forever. This client-side PDF processing guarantees absolute privacy, making Flipp one of the most secure PDF tools available.

Our Core Philosophy
Powered by Open Source
Flipp stands on the shoulders of giants. Our privacy-first PDF tools are made possible by an incredible ecosystem of open-source technologies. The engine behind our fast and secure processing includes trusted, industry-standard libraries like PDF.js for parsing, pdf-lib for complex manipulation, jsPDF for generation, JSZip for file bundling, and Tesseract.js for powerful client-side optical character recognition (OCR).
By leveraging modern JavaScript (ES Modules) and these robust libraries, Flipp delivers a desktop-class editing experience directly in your web browser.
