Smallpdf alternative

The private Smallpdf alternative — your files never leave your browser

Smallpdf is one of the most popular PDF tools on the web, but every task — merging, converting, compressing — requires uploading your file to their cloud servers first. Convertoza performs the same conversions locally in your browser using WebAssembly and standard browser APIs: no upload, no cloud, no privacy risk. It's free, fast, works on any device, and never asks you to create an account before downloading your own file.

    Local processing isn't a promise in a policy — it's how the app is built. You can verify it in your network tab.

  • Generous free tier

    20 conversions per day with no watermarks, no nag screens, and no forced sign-up wall.

  • Works offline

    After the page loads, most conversions keep working even if your connection drops — ideal on planes and trains.
