PRIVATE BY DESIGN
The core product principle is simple: when a file operation can be performed safely in the browser, the browser should do the work.
You choose a file, the browser reads it locally, the tool performs the supported operation and your browser creates the output for download.
For supported workflows, AllOnline.tools does not need an application server to receive the source file just to perform the transformation.
Processing engines are loaded per tool instead of shipping every engine on every page. CPU-heavy work can be moved into Web Workers where appropriate so the interface stays responsive as the toolbox expands.
Browser-local processing reduces one class of risk; it does not eliminate every security concern. Dependencies, browser behavior, hosting configuration and future integrations still need ongoing review.
