Support routes
Did the app crash?
Monstera keeps crash reports on your computer, which is on by default. The next time it starts after a crash, it asks "Send us the crash report?" Choose Share… and the Windows Share sheet opens with the report and the diagnostics log attached, so you can send it from your own mail app. Nothing is sent unless you send it. A crash report is a snapshot of the app’s memory and can contain parts of the documents that were open, so review it before you send it. How crash reports work
Found a security issue?
If you discover a security vulnerability, suspicious behavior, or a PDF that causes Monstera to behave unexpectedly, please report it privately so we can investigate it responsibly. Use Report a vulnerability on the Security tab of the GitHub repository, or email us.
report@monsterapdf.com or report on GitHub (opens in a new tab)

Have a feature idea?
Tell us about the problem you’re trying to solve, not just the feature or button you want. Understanding the problem helps us build something genuinely useful. We read every suggestion we receive.

Steps To Take When You Encounter An Issue
Providing specific details helps speed up our support process. Please follow the steps below if you encounter an error with Monstera.
- Update Monstera first. Open the Microsoft Store, install the latest version, then check whether the problem is still there. Some bugs are already fixed.
- Note your version. Find your version in Help › About Monstera.
- Describe what happened. Tell us what you expected would happen, what actually happened, and the steps that caused the problem.
- Attach the smallest useful file. If the problem only happens with a particular PDF, attach that file if it is safe to share. Remove any confidential information first.
- Include the exact error, if there is one. Screenshots, error messages, or other details that help us reproduce the problem are useful.
- Send the report to report@monsterapdf.com with a short summary in the subject line so we can identify it quickly.
Please do not send confidential documents
If you need to share a file to demonstrate a problem, remove any pages that are not relevant and redact sensitive information first. Whenever possible, use a harmless sample instead of sending private or confidential documents.
