What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
App produces error during install for smartphones. Should favor browser entry, or at least make link more prominent. Also, the way that some of the advanced features are not available to a subscription is a bit misleading they way they are presented IMO... At the very least, the base subscription should provide limited quantities of some of the more advanced features... (monthly counter etc.) ~ Because the casual user may really benefit from these features (in low volume.) And there's little incentive to not just "get by" with the free services if they're not available.

Simple and easy to use even for the novice computer user. It's made my documents look professional and well presented which has received a few thumbs up from people I have forwarded the documents to.

I moved across the country since I had my brochure designed and printed. Meanwhile Covid-19 restrictions gave me the extra push to go 100% virtual with my business. Thus the online marketing material had to be accurate and up to-date. [pdfFiller made it easy for me to easy to update/edit my existing marketing materials.

What do you like best? Easily convert PDFs to word and rotate pages withing an improperly scanned PDF What do you dislike? The text writing font options are few and when the writing box dissapears the text changes size and font that what it was displayed. Recommendations to others considering the product: More font options and ability to match font of the original document. When editing in a document your software changes the size and font of the edited text. What problems are you solving with the product? What benefits have you realized? Filling out forms and signing documents.

I love the product and help via chat has been great but it would be nice to have some training videos to help me get up and running with the product. This is my busy season and it slows me down having to chat for help a video would be so much nicer. Thank you for a great product.
