Questions

Are my files uploaded anywhere?

No. This page loads the PDF tools into your browser once, and then works on your file right there on your phone or computer. The file is never sent to mwai or anyone else. Many other PDF websites upload your file to their servers; this one does not.

Which letters can I use?

English letters, numbers and common symbols. Hindi and other scripts are not supported yet.

Can the watermark be removed later?

It is drawn onto the pages, so ordinary PDF readers cannot remove it. Determined people with PDF editing software can still remove most watermarks.

Is it really free?

Yes. There is no sign-up, no limit on how many files you use, no watermark added and no ads.
