## Product: PDF Pro 4
**Brand:** Markt + Technik

## Pros
- Offers a one-time purchase option with no subscription, making it great value for basic to moderately complex PDF editing tasks.
- Includes useful features such as OCR, signing PDFs, creating forms, editing, converting, commenting, and page extraction/combining.
- Supports editing multiple PDFs simultaneously and resizing pages of different dimensions within a document.
- Provides multiple viewing modes (Dark, White, Modern, Colorful), which some users prefer over competitors like Nitro Pro.
- User interface is reasonably intuitive, especially for those familiar with Acrobat Pro or Nitro Pro, with a helpful Quickguide PDF included for easier onboarding.
- Developed by a reputable German company, providing some assurance of quality and legitimacy.
- Performs all necessary PDF functions effectively without overwriting edits from other PDF software.
- Compatible with Windows 7, 8.1, 10, and 11, covering a broad range of systems.

## Cons
- Editing performance can be unreliable, with reports of file corruption and messed-up PDFs during editing.
- Licensing issues emerge after a few months, causing the software to suddenly stop working, which is a significant inconvenience.
- Customer service is difficult to reach and unresponsive, especially for license or technical support problems.
- Combining PDFs can be awkward due to a clunky "JOIN" function, and the PDF display often shows pages too small for comfortable reading.
- Printing features are limited and unusual; users often need to use workarounds like "Microsoft Print to PDF" and cannot easily print just the current view or crop images before printing.
- The program’s print font and general display are hard to read, creating accessibility concerns for users with vision difficulties.
- The software isn’t very intuitive overall, often requiring trial and error to figure out functions.
- Some users experienced non-working product keys and poor seller communication, which impacted their purchase experience negatively.

## Bottom Line

If you’re looking for a budget-friendly PDF editor with solid basic to mid-level features and prefer a one-time purchase over subscriptions, PDF Pro 4 delivers on many fronts—especially with OCR, signing, form creation, and multi-file editing. However, beware: reliability issues with file corruption and licensing, coupled with poor customer support, have frustrated users enough to make this a gamble for heavier or mission-critical PDF work. For a smoother experience or if you need more robust and user-friendly PDF editing with better support, you might want to explore alternatives or mainstream options.
