What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I had to refile my last 4 years 1040 and all tax docs. After going through the IRS web docs but unable to edit them I found all the docs on the PDFfiller website. After a little work with the editors I was able to process professional docs. I bought a year sub and look to see if I can use this app for other business uses.

While easy to use, plenty of features and very helpful for my needs, even with the follow-along snap menu to the right, it is simply not an intuitive dashboard..

What do you like best?
It works. Easy to use platform. I've subscribed for several years and they continue to make improvements. I tried docusign and this was just as good.
What do you dislike?
I don't like that it won't link up with business accounts on OneDrive so I can't store my files on OneDrive. Really would be nice to have them fix that! Also for some weird reason, the system only can connect with personal accounts. Sometimes, it's not easy to find my documents. Finally, the plug-in for Chrome doesn't always work well. Usually, it's just better to go into the app itself.
Recommendations to others considering the product:
Compare the functionality you need to what it offers. I suspect you'll find it's sufficient.
What problems are you solving with the product? What benefits have you realized?
Send out paperwork for signatures and fill out paperwork online instead of printing, signing, and scanning it.

PDF filler proved to me that they care about clients. PDF filler proved to me that they listen to the customers and react to client questions and comments quickly and with a positive approach.

PDF filler works great and has helped print some documents that we used to have to type. Less time spent on creating forms for the clinic. Document creation - used it for paper billing, in house forms, and staff checklists. Easy to create the document and implement Alignment is sometimes different on the document than what prints. Can take a little trial and error to make it align perfectly.

Effortless Document Filling with pdfFiller! Overall, pdfFiller has been a great tool for me. It's saved me so much time and hassle, and I'm really happy with the results. Highly recommend! I've been using pdfFiller to fill out documents for a while and I have to say that I'm very impressed with its ease of use! It's incredibly straightforward and makes it so easy to fill in the blanks on forms. Plus, they have a wide selection of templates that make my job even easier! The only downside to pdfFiller is that the free version has some limited features. If you need more robust features, you'll have to upgrade to the premium version.

Data safety is the primary reason professionals choose PDF files to share and store information. That’s why it is important to pick a secure editing tool when managing documents.

Use editing features to type in text, annotate and highlight. Add fillable fields and send documents to sign. Change a page order. Add and edit visual content. Ask your recipient to fill out the document. Once a document is completed, download it to your device or save it to the third-party integration cloud.
