How it works
Three steps, and your file never leaves the tab it is in.
- 1
Pick a tool
Search or browse all 100 tools and open the one you need. No account, no install.
- 2
Your device does the work
The tool runs inside your browser tab, on your own computer or phone. Your file is never sent to a server.
- 3
Download the result
Save the finished file straight away. Close the tab and nothing is left behind.
Our biggest difference
Your files never leave your device
Most online PDF sites upload your file to their servers, process it there, and ask you to trust what happens next. pdfcosmos does not upload anything. The tools run inside your browser, so your documents stay with you.
-
Processed in your browser
The PDF engines run on your device, not on our servers.
-
No uploads
There is no upload step, so there is no copy of your file anywhere else.
-
Nothing is kept
Files live in the tab's memory only. Close it and they are gone.
-
Check it yourself
Open your browser's Network tab while you work. You will see nothing sent.
