Paplume vs PDF24
This is the comparison where we must be most careful, because PDF24 is genuinely free, has no account system, and is a well-loved product. We are not claiming PDF24 tricks anyone. The difference we verified is architectural: PDF24 uploads files to filetools*.pdf24.org for processing and is funded by ads; Paplume processes files locally in your browser, with no ads, funded by a future Pro tier for AI features.

FAQ
How can I check that Paplume really does not upload my file?
Open your browser DevTools → Network tab, then process a PDF with any local tool. You will not see a single file-upload request — processing happens in your browser via WebAssembly.
Is PDF24 really free?
