A free Smallpdf alternative that never receives your file
Smallpdf is a polished product built on a conventional server model: you upload your document, its servers do the work and send the result back. PDF100 works the other way around. The processing code runs in the page you have open, so the file has nowhere to travel. Here is an honest look at the difference, including what Smallpdf still does better.

What PDF100 does instead
PDF100's tools are code that runs in the page you are looking at. Your browser opens the file, your own processor does the work, and the result is saved straight back to your disk. There is no upload step to secure, no retention period to publish and no server copy to lose.
Check it in thirty seconds
Open any PDF100 tool, open your browser's developer tools, switch to the Network tab and run a file. Nothing carrying your document goes out. Or load the page, turn off Wi-Fi and keep working. Here is the full method, which works on any site.
Where Smallpdf is the better choice
This page is not trying to win an argument. If you need any of the following, Smallpdf is the right tool:
Smallpdf wins
AI features
Chat with PDF, summaries and translation need large models running on servers. PDF100 has none of that.
Smallpdf wins
Conversion fidelity on complex layouts
Server-side Office engines usually reproduce complex Word and PowerPoint layouts more faithfully than a browser can.
Smallpdf wins
Cloud storage and syncing
Smallpdf can keep your files available across devices. PDF100 deliberately stores nothing.
Smallpdf wins
Apps and teams
Mobile and desktop apps, team billing and admin controls. PDF100 is a free website only.
