What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I wanted to be able to duplicate a filled form and make a couple of changes. Then save with a new name. I did download and rename before I did this. glad I did. PdfFiller overwrote the file. All is well since I downloaded the original.

What do you like best?
It offered me a complete fillable PDF forms using data from spreadsheets in a matter of minutes. It Kept all of my completed forms secure and organized in one folder and I could easily access them anytime from its desktop software or its mobile application. PDFfiller’s add-on for Google Spreadsheets spared me tons of time I would use filling out multiple forms with data from my Google Sheets by hand. PDFfiller instead allowed me to automate the entire process by quickly merging data collected from the spreadsheet’s cells with fillable fields in the forms. It also helped me to easily share completed forms with my teammates and colleagues directly from it instead of having to download and share on various platforms separately.
What do you dislike?
It's a bit slow and too many requirements to return to the dashboard to make a new order or start over. It's a little difficult to use and I didn't really find the editor interference convenient at all. Also if you're using it online you should have a medium to fast internet connection as it works terribly with slow connections and lags a lot.
Recommendations to others considering the product:
It helps you export spreadsheets into PDFs in secs and saves you all the effort and time you'd have to go through if you tried to do it manually. I totally recommend it.
What problems are you solving with the product? What benefits have you realized?
I personally use a lot and to solve many issues I go through with spreadsheets. I deal and work with spreadsheets very often be it for registration of events we organize in ASCE student chapter or for our technical work in construction filling in dimensions, quantities and/or areas. I would always face this problem when I have to export the spreadsheet in a PDF format as every time the pdf file ends up being incomplete and I lose a lot of my spreadsheet data because the spreadsheet has no size restriction as in PDF; Landscape A3 or Letter A4 sizes and even if it put all of the spreadsheet content in the PDF, the font size is becomes very small and unreadable. So I used this software ad ever since It became really super easy to export sheets into PDFs without losing any data and only with a few clicks.

the experience was mostly good, however, when coming from a google doc and putting the document here to convert into a pdf, the drop down tabs that were originally in the google doc did not work- in that way, it was tedious.

What is digital certificate PDF?
Digital certificates are electronic credentials that bind the identity of the certificate owner to a pair of electronic encryption keys, (one public and one private), that can be used to encrypt and sign information digitally.
What is a PDF certificate?
A certificate stores the public key component of a digital ID. For more information about digital IDs, see Digital IDs. When you secure a PDF using a certificate, you specify the recipients and define the file access level for each recipient or group.
How do I certify a PDF document?
On the Protect tab, in the Certify Document group, click Certify.
On the Certify Profile Wizard, choose the actions you want to permit from the Permitted actions list.
Click Next.
Select a digital ID to certify with, and choose whether to make the certificate visible.
Click Next.
What is a PDF signature?
An electronic signature, on the other hand, is merely an image of your signature overlaid on top of a PDF document. You can do it with all kinds of apps, and it's what most people will require when they send you a document to sign. Send them a PDF file with a digital signature, and they won't know what to make of it.
