What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Initially, it was a bit confusing. However, after using the program a few times, I am delighted. I very much like the fact that I can take a printed form, scan it, and then fill it in and print it. The result is very professional looking. Still not sure how to change fonts.

PDF Filler is very convenient and well thought through. Now, if it only integrated with my tax return online service provider and auto-populated forms, ditto all others, it would be perfect.

A must have for your business Overall, this software is a very useful, less time consuming, and efficient addition for my business. I love that I can complete and sign required documents on the go with no hassle, without having to print and physically complete and sign any document. I love that this software is so convenient and easy to use. Its a must have for completing and signing documents for your business electronically in a quick and efficient manner. The mobile app for this software is not that easy to use as the online (desktop) version.

PDF editor that does the job. It does the job to edit documents to avoid printing and scanning official documents. I was impressed that I could place the cursor and be able to edit any online document. This enabled me to print or send a document without having to print ad scan the document. It was difficult lining up the cursor or lining up where I could input information on the document. I would have appreciated a tutorial that was available at the beginning of the trial or purchase.
