I like it but wish there was an edit instead of erase and text to change something. There may be but I'm not aware of it so a webinar would be very helpful.

I really like the fact rhat PDF filller allows me to work on very important PDF documents that I need to fill out but I still have trouble navigating these documents which is why I only gave 4 stars. Maybe with better instructiins...

great I run a water and sewage restoration business and this had made it possible to do all my emails and bids in the field. This program has made me thousands of dollars. As a business owner with no computer traning and self taught to pick at a keyboard. I now can compete with the business who run 5 employees doing paperwork and emails. This allows me to do the work of 4.

What do you like best?
I started using PDFfiller as an alternative to Adobe Acrobat, which is not available for Chromebook. I expected it to be something I could use to make small edits to PDFs and also to fill in non-fillable forms. It has proven to be way WAY more than that. I like that the program is incredibly versatile
What do you dislike?
I wish I could save files to by Google Drive into the folders that I want rather than having to move them from the PDFfiller folder.
Recommendations to others considering the product:
Try it first, but it really is that good.
