What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
After contacting customer support, I was told that certain web browsers are more compatible than others in completing forms. Once I changed from Mozilla Firefox to Chrome, I was able to complete all fields of the form without problems. But it would have been helpful to publicize this information on your website so that much time was not wasted.

What do you like best? I enjoy PDF Filler because it is not as expensive as Adobe Pro, and it allows me to quickly edit, sign, and return any PDF document I would normally need to print out, and scan back to myself. What do you dislike? One dislike I have is the fact I need to download everything. It would be really helpful if everything would be automatically saved on something like a onedrive (cloud storage), where it would be automatically saved. This way, I can have a local folder on my computer without needing to go into the webpage and click download What problems is the product solving and how is that benefiting you? I no longer need to waste paper to download a form, and fill it out. Normally I would need to do this, then scan it back to myself. now I can upload, edit, and sign the form which saves a lot of time.

What do you like best? PDF Filler is extremely easy to use and navigate. I've never experienced any lag or difficulties in using the software. Signatures are easy, dates are easy to inpute. What do you dislike? You don't get to really choose where files are saved when you download them. What problems are you solving with the product? What benefits have you realized? I've been able to easily fill out and save consolidation agreements, settlement letters, and anything else that I need and don't have time to print out and sign just to have to scan it in. It's definitely a time saver!

What do you like best? I personally like using PdfFiller over other programs like Adobe to edit my documents because the site is more user friendly. I can do everything I need to quickly and efficiently. What do you dislike? I wish there was an option to combine documents. You can delete pages but not upload new ones. What problems are you solving with the product? What benefits have you realized? I used to use Docusign to add digital signatures but now I used pdfFiller instead. It's great for adding quick signatures on internal documents without the waste of printing and hand signing forms as I did prior.
