Smallpdf is one of the most well-known online PDF platforms, offering a polished interface and a wide range of tools. Privatool is built on a different philosophy: zero server uploads, complete client-side processing. Here's how they compare.

Smallpdf's rate limiting
Smallpdf's free tier limits you to 2 PDF operations per hour. After that, you must wait or subscribe. Privatool has no rate limiting — all tools are free with no hourly caps.
Privacy policy comparison
Smallpdf's privacy policy confirms files are processed on their servers and stored temporarily. They use SSL and claim to delete files automatically, but you are trusting a Swiss-based company with your document contents.
Privatool has no server-side file processing for any free tool. Your files are processed entirely in your browser tab using WebAssembly and JavaScript. Once you close the tab, no trace of your file exists anywhere outside your device.
Pricing model comparison
Smallpdf charges for premium features on a subscription basis. Privatool's core tools are free with no paywalls — the business model is display advertising, not subscriptions.
