pdfFiller scores top ratings on review platforms
I am a self represented defendant in a small claims case. I cannot afford an attorney. With the robust capabilities, and plenty of time on my hands, I can plow through the case law and ca civil codes, but I can't readily find and fill out forms. PDFfiller has the forms I need and does a credible job of filling them out.
The pdf filler has been excellent to use to date. I haven't explored the other options available, such as sign and send, although, I will definitely look into a full options account.

Converting from and to pdf, faxing and email options along with notarize service
It is useful. Only thing I would like is for it to figure out what font I had on the document BEFORE I edit it. I have contract templates that I use that I have to edit sometimes and finding the font that will match that size and actual type is very difficult. i usually end up just dealing with whichever one I find. If there is a way to do that, please let me know via email.
What do you like best?
I like to be able to upload multiple documents and then have the ability to rearrange them if needed, or remove, or even add to my entire document.
What do you dislike?
I do not like that the desktop extention frequently has errors, and continues to lag. I also do not like that the fax portion is uncustomizable.
What problems are you solving with the product? What benefits have you realized?
It helps me to add or remove specific line items, which I do not want others to see. It also allows us to add pictures to the PDF documents, such as signatures, and or stamps for notary.
Works Perfectly!
I don't typically need a lot of editing, but what I do need this service does perfectly. No guessing about what you need to do like with some other apps, and although I do sort of enjoy the uncertainty of wondering whether things will actually edit or not pdfFiller has definitely helped me be more productive.
I like it very much, I think it has great fearures and it has helped me a lot... so much that I was ready to become a paid user. However, 2 of the last documents I uploaded to the system were cut-off and seriously changed (different format, things missing, etc) the uploaded document did not show as an identical version of the original document and that made me change my mind. I use it for contracts and they need to be exactly as the original document. These are legally binding documents, so because of that, I decided not to continue the service after the free trial ends.
