How to get in touch with me

I love getting feedback, bug reports etc. about my software and my websites. Send me an email to [email protected].

If it's about SumatraPDF, use forum for questions or submit bug reports and feature requests.

If you want to send a quick message, anonymously (I will have no way of getting back to you), use this form:
