Questions
Is it free to compare two PDFs?
Yes. It’s free and needs no account. It runs in your web browser, with nothing to install.
Is my PDF uploaded?
No, not without an account. Your PDF is opened and worked on in this browser tab, and never sent to our server.
Is there a file size limit?
Not as a guest. Your file never reaches our server, so the only limit is what your device can handle. With a free account, each PDF kept in your library can be up to 100 MB.
Can I compare two PDFs on my phone?
Yes. It works in the web browser on a phone, a tablet or a computer.
