What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I was desperately trying to edit a pdf copy of the P&S and we could not convert it to a Word document. Finding your website where I could make edits to the form, made my life a whole lot easier. However, I work for a law firm and we normally do not have to do these types of documents. So I am afraid I will have to cancel once the document is finalized. At least, I will keep your website as a place to go to if there is a future need. Could you please cancel my membership after the 30 days I already paid? Thank you.

What do you like best?
PDFFILLER has been one of the best platforms I’ve used in client document transmission. The price is unmatched for the services available and the HIPAA compliance seals the deal.
What do you dislike?
The only downside is how long some forms such as registration can take to complete when adding in the initial fillable fields.
What problems are you solving with the product? What benefits have you realized?
Many of my clients are throughout the country, so the ease of securely transmitting documents while maintaining HIPAA compliance is the best problem solved. I recently discovered the ability to have documents faxed digitally through the services and it’s cut down on my physical paperwork.

Accounting Assistant
This software made it easy for me to complete a single 1099-MISC that i needed and that i wasn't able to use my current software for. I was able to quickly create the document and send it out to the necessary party on a time crunch.
This would not be good to use for a large amount of 1099's but, it did meet my needs.

This is the best site for PDF conversion
This is the best site that I have ever come across in terms of PDF converters and I highly recommend it. I was able to work on my piece for days with no fear of losing it, something which happens with some converters making you begin it afresh. I recommend this site for anyone with a large document to work on.

At first I had difficulty understanding how to use PDF Filler maybe because the way the dashboard was set up was that there were too many icons that made it seem too overwhelming.
2022-02-08
The learning curve is not too steep. I'd feel more confident with it, if there was a way to save the document other than clicking DONE which closes it....it's better than the government forms I've hassled with!
