About

Monstera PDF Editor is a free, open-source desktop application for Windows 10 and 11, with more than 150 tools for editing, converting, organizing, and securing PDF documents without subscriptions, accounts, or watermarks. Users can edit PDF text and objects, merge and split files, manage pages, create and fill forms, add signatures and annotations, compare documents, and permanently redact sensitive information. OCR in 14 languages makes scanned PDFs searchable. The built-in AI assistant supports 10 providers and can summarize, analyze, and answer questions about documents using the user's own provider credentials. Standard PDF operations run locally, and Windows AppContainer isolation helps protect the system while documents are processed. Distributed through the Microsoft Store, Monstera is licensed under GNU AGPL-3.0, and its source code is publicly available on GitHub.

Pros & Cons from Real Users

Pros

  • - Clean, minimal interface - Ability to work completely offline - Ability to view different layers of PDF documents
  • Only cross-platform PDF Editor. The functionality is good, and I would not hesitate to recommend the product if not for the stupid direction they are going under the new owner.
  • Feature-Rich: PDF Studio offers extensive PDF editing and annotation tools. User-Friendly Interface: The interface is intuitive and easy to navigate. Robust Annotation Tools: Includes various tools for document review and collaboration.
  • Pencil feature - This works well on my surface pro. I can use the pen to draw and write comments on documents, and the marker to highlight text. Page resize - I have used this to resize from A4 to letter. As well as resizing the page, you can also scale the contents which is very handy! Redacting - I have used the redaction feature to cut sensitive information from documents. I was able to mark the areas to be redacted and then apply them in one hit. Works great!
  • It does everything you need from a Professional PDF Editor (like Adobe Pro DC) but without the stupid monthly subscription that places like Adobe would charge you.

Cons

  • - Small controls sometimes hard to see in bright daylight
  • The Apryse support department has gone downhill - they will not even test the product when a bug report is filed with an example file, insisting that the user jump through hoops including reinstalling the product and showing screenshots of what was done, even when there is only one way to do the thing described in the report. The new owner does not honour the perpetual licence conditions, which included free point release updates, and discounted annual upgrades, insisting that users go onto a more expensive subscription just to get what they already paid for. The user interface has regressed, replacing window decorations with their own and not picking up colours or settings from the selected theme and thereby losing integration with the system user interface, both visually and in the way the windows respond to user interaction.
  • Performance Issues: May struggle with large or complex PDF files. Support and Documentation: Less extensive support and documentation compared to Adobe. Not Open-Source: Requires a paid license and is not open-source.
  • Sometimes the 'Edit text' tool can be tricky, but I was able to find the content in the sidebar and edit it there. Also, I think the icon could perhaps be different.
  • It's not the prettiest UI in the world but I can live with that :)
