pdfFiller scores top ratings on review platforms
I am a Special Education teacher, and to be able to take pdf files general education teachers are using and enter in text boxes so my students can type into the pdf is very helpful for my writing challenged students. I can also fill in answers to study guides and email or send home a paper copy for my students to study from also.

PDF creation and editing is very convenient and useful.I like the way to add or delete a textboxSending and receiving documents is convenient and secure.
I have no negative thoughts about this program.
Great software for the money
Great software for the money. Has helped tremendously with our business needs. The only thing I would change is the LinktoFill. This gets confusing due to saving a file when you make updates to it and then you end up with having the two files. there should be an option to update exsiting file. Besides that, great program.
Thought I had cancelled my subscription…
Thought I had cancelled my subscription but turns out I didn't and it went out the next month... got in touch with customer support and they cancelled my subscription and refunded the amount taken with no issues.. fast and polite responses as well.. very impressed.
I have had several emergent documents sent to me in PDF-without PDF Filler I was having to print-complete form and either scan the document to my e-mail or fax to the appropriate recipients. PDF filer has saved me an astronomical amount of time :)
Fast and effective response
When I contacted them through their Chat feature my problem was resolved there and then. Instant response, and then follow up emails to make sure everything was ok. This is how customer service should work but so often doesn't.
