Common questions
Is the KovaPDF desktop app free?
Yes. It follows the same rules as the website: no daily task count, and a fair hourly limit only on very heavy use. Signing in raises that limit.
Which tools work without internet?
Merging, splitting, rotating, cropping and organising pages, page numbers, watermarks, headers and footers, passwords, picture conversions, Bijoy and Unicode conversion, and getting the text out of a PDF or a picture. In the app, every tool says whether it works offline.
Are my files uploaded?
Not by the tools that work offline: they read and save the file on your computer. Tools that need internet send the file over an encrypted connection, and the working copy is deleted as soon as your job finishes.
Why does Windows show a warning when I install it?
Windows shows "Windows protected your PC" for apps from publishers it does not know yet. Choose More info, then Run anyway, and the installer starts.
Do I need an account?
Every tool works without an account. Sign in from Settings for a higher hourly limit.
How do I uninstall it?
Open Windows Settings, go to Apps, find KovaPDF in the list and choose Uninstall.
Does it update by itself?
Yes. When a new version is out, the app downloads it, checks it against its published fingerprint, and installs it when you restart the app.
Can I use it on more than one computer?
Yes, on as many computers as you like. It is free.
Is there a Mac version?
Not yet. On a Mac, every tool works in the browser at kovapdf.com.
