What do other developers think?

JPedal is absolutely easy to use and it provided the best results of all libraries we tested over the years. We need to create renditions of PDF files so that people can view them conveniently in the browser. For our purposes, this is better than displaying the PDF natively in the browser.

- Roman K. (Developer at German Digital Big Data Platform)

We use this library to provide image representations of PDF documents for use in our internal business applications. (Thumbnail images, Web-based page renderings, etc.). JPedal's ability to image PDF documents is the feature we use most often in our internal business applications. I should also give a shout-out to JPedal's support team. They have been absolutely fantastic.

- Executive Sponsor in Wholesale

Great conversion library with excellent support. The library converts pdfs to any kind of image in a fast and reliable way. In case of an issue the support reports back immediately and solves the issue quickly.

- Consultant at a SME working with Big Data

Solution to a complicated XFA PDF problem. I had problems with one type of PDF document displaying. Mark helped me get that working and then later helped me understand the security risks with the problem file type. The support is worth it.

- Professional Veterinarian & part-time Developer

Support for JPedal is done extremely well and for continuously using the software, what the customer needs is good support for the issues we face. And it is superb in that respect.

- Developer at a large multinational corporation

This solution is very easy to use. The conversion is very accurate and there are many options available to solve a wide variety of use cases. JPedal is well documented. New features and updates are frequent, and support has always been quick to solve issues and prove help. I can’t recommend them enough.

- Customer in Publishing Company

Support has been on point. A requested feature was added within a day. 10/10, would recommend.

- Johannes D. (Developer at a small business)
