Stop handing over your sensitive data
There's a reason Smallpdf
Wants Your Uploads.
Smallpdf limits your daily usage and forces you to upload files to their servers just to perform basic modifications. Why? Data-harvesting and subscription lock-in. LumioPDF is completely uncapped and runs natively inside your browser.
How it Works: Device vs Offshore Cloud
They force uploads to offshore servers. We process everything directly within your browser using modern WebAssembly.
