What do you like best?
I can send as many documents out for signature as I want. No restrictions. I used to use Adobe, but they had a cap on the amount of documents you can send for signature. When I tried to get that upgraded, they had outlandish prices for this same service. With PDFfiller, I can send all the documents I want and I'm also able to save all of them securely.
What do you dislike?
I wish the PDF conversions didn't come out like pictures. When I convert a PDF to Word, it always comes into Word as a picture instead of being able to edit the document. As a recruiter, I receive a lot of resumes that need some work before we can submit them to clients. I still have to use Adobe for this function, so now I'm paying for two PDF programs. I can't just stay with Adobe though because of the above mentioned issues.
Recommendations to others considering the product:
If you need eSignatures, this is the program to go with.
What problems are you solving with the product? What benefits have you realized?
Remote onboarding is a breeze with PDFfiller. I am able to send HR documents to people across the country and still get them to work on time. I'm in VA and have to get employees to work in all states across the country, as well as oversees. We have to get documents to them for signature and faxing doesn't always work. With PDFfiller, we can send anyone any document and get it back fully signed by them. It's truly wonderful.
Angela Camacho
What do you like best?
Ease of changing a PDF to suit a particular need and/or make corrections to a PDF to present to a different customers
What do you dislike?
Only downside is not having an autosave when working on a PDF and after being distracted by other people returning to the PDF to find you need to restart.
Recommendations to others considering the product:
Quality solution to alter PDFs to be tailored to suit a particular presentation to a client
What problems are you solving with the product? What benefits have you realized?
Changing PDF's to be tailored and personal as per each individual client that we present to

Outstanding Online Support I have used Pdffiller for the past 4 years to file tax returns for an investment group with over 40 members. I made an error when creating my template and when I went to print the 40 documents an erroneous number was appearing, the result of my error in creating the document. Fortunately Pdffiller has an online support staff. So many online companies require you to submit a ticket and then promise a 24 to 48 hour response time. Pdffiller offers that option but they have an outstanding online chat support. I had the benefit of working with Ryan and got access to him immediately upon opening up the online chat support. This was in the evening but Ryan thoroughly researched and tested my issue. Sadly the only option that appeared to be the answer was to create a new set of 40 documents which Ryan was willing to teach me how to create the docs in way that would avoid this error. When I expressed my issue with not having another 6 hours to re-create my work, Ryan persisted in finding a work around that was very creative and saved me from over six hours of new work!!! Needless to say I was ecstatic!!! Thank you Pdffiller for not only a great product but an online support staff that truly cares about helping customers get the results they require!!

Ridiculously time-saving and easily customizable PDFfiller is a lifesaver as an office assistant, as I'm able to quickly populate imported forms with the info I need without filling them in by hand-which saves me time, ink, and effort! Little drawbacks to using this-while some files I import aren't already OCR-friendly, it's easy to navigate around and create text input on my own.
Julian S.
I was able to edit the pdf… I was able to edit the pdf appropriately. When I converted to a word document, the places I had checkmarks in the pdf did not align properly in the word document, but that's really the only issue I had.
Linda Catlett
Cancelling a subscription can be an intimidating and anxiety creating experience. NOT WITH THESE PEOPLE!!! Today I logged in to my account. ***** linked in as my Chat contact and in less then 1 minute the subscription was taken care of for me!!!! I have had to fight too many providers about cancelling subscriptions so THIS WAS REFRESHING!!! Such a contrast and it makes me want to stay connected with them if I ever need their services again.Don't hesitate to access their services and products.
