Most "free online tools" upload your files to their servers and process them there. These tools work differently: the processing happens on your machine, in your browser.
PDFs, images and text are processed with in-browser technology (WebAssembly, canvas, Web Crypto). Your files are never sent to a server — there's no server-side processing at all.
Open your browser's DevTools Network tab while using any tool: you'll see no file ever leaves your machine. Or load a tool, disconnect from the internet, and keep working — it still runs.
No accounts, no file storage, no processing queue. When you close the tab, your data is gone from memory — there's simply nothing on our side that could be breached or sold.
