Transparent answers about our client-only architecture, privacy guarantees, and free document tools.
How does Aback PDF process documents without uploading them to a server?
Aback PDF processes everything directly on your device. When you select a document, your browser performs all rendering, organization, and modifications locally in your device memory. Your files are never uploaded over the network.
Is Aback PDF truly 100% free with no watermarks?
Yes. All core PDF utilities (merge, split, rotate, convert, watermark, flatten, and metadata inspection) are completely free. We never stamp watermarks, restrict page counts, or require credit cards or user registration.
Are there any file size or page count limits?
Because processing takes place entirely on your device, there are no artificial server upload caps. You can merge, split, and convert large documents containing hundreds of pages, bounded only by your computer or phone available memory.
Can I use Aback PDF offline?
Once the page is loaded into your browser, core tools can continue functioning even without an internet connection, because no remote servers are required for processing.
Is my confidential legal, medical, or financial data safe?
Yes, completely safe. Because files never leave your computer, there is zero risk of data interception, cloud breaches, or third-party unauthorized access. You can verify this at any time by opening your browser Developer Tools (F12) and checking the Network tab.
What browsers and operating systems are supported?
Aback PDF works smoothly on all modern web browsers, including Google Chrome, Firefox, Apple Safari, Microsoft Edge, and mobile browsers on iOS and Android.
