I have tested it and every elements concerning my line of work are deeply thought out and very crisp. I had a problem of sending a folder but the solution is in merging the files to create one new file to send. The software is brilliant and less costly than all the competition I have tested.

It took a few minutes to learn navigation, but once figured it out all is good. Still many features that i have only scanned thru that really look very helpful.

I really enjoy using PDF Filler! It offers a great variety of tools that make working with PDFs so much easier and more efficient. The features are user-friendly and save me a lot of time. My only wish is that the monthly subscription was a bit more affordable, as it can feel a bit pricey over time. However, the quality and range of features make it a valuable tool that I keep coming back to. Overall, it's a fantastic service for anyone who works with PDFs regularly!
