What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
What do you like best?
I like being able to edit and/or fill-in .PDF documents. I also like that I can retrieve documents that I have previously worked on.
What do you dislike?
I'd like to be able to change the font in the text option, as it doesn't always look right if mismatched.
Recommendations to others considering the product:
I'm not sure how I first heard of PDF FILLER, but am I ever glad that I found it. My advice would be to try it out and see if it suits your needs. I like many of its features, especially the left pane that shows the document pages, and the ability to select only those that you want to include in a print or save maneuver.
What problems are you solving with the product? What benefits have you realized?
One use that I have for the program is for one of our telecommuter workers - so that she can enter details on employee time cards, and it looks better than handwriting in notes. Uploading the documents she needs is a breeze, and the program alerts me to activity, for example, when she emails the documents to us for distribution.

Easy PDF completion app Overall from what I've used, this has been a really great way to complete and sign documents. I liked that you can basically fill out forms but digitally. Everything is digital these days and instead of having to download and do a bunch of cumbersome steps to complete a document, you can do it straight from the app. It's much easier and cleaner. I wish you could edit things and make changes. If you need something changed you'd have to contact the other party and have it changed then resent. But even so it's not that big a deal and it's still a great software.

PDFFiller saved my books! PDFFiller saved my books! As a young author, I had no idea what I was doing and deleted my original documents once the books were published. I only kept the print-ready PDFs. Years later, I realized there were a lot of spelling mistakes and errors in them, and wanted to re-publish. Since the books had photos, I couldn't simply convert to a doc. Most PDF tools online didn't work, or put on watermarks. PDFFiller allowed me to edit the text in the PDFs, to correct the spelling mistakes, and merge the documents into one cohesive PDF again. I was able to republish an edited book without the original documents, thanks to PDFFiller. The one thing I missed that could make this a fantastic tool- the original book was 8.5x11. I wanted to republish at 6x9. I ended up having to resize it through a different tool, which simply shrunk everything instead of being able to directly resize the content. Due to that, the book appears much smaller on the pages than it should, and I've received some complaints that it's harder to read. If PDFFiller had a viable PDF resize tool that worked to resize the content versus simply shrinking the document, it would be a stellar addition to the repertoire.

Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed the 1year subscription. Advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. They communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month and cancelled my future subscription. I would happily use this again. Thank you.

Just retired and pdfFiller saves the day. Just retired and found several entities I need to work with to get all my personal business done still require faxing and filling out lots of documents. pdfFiller has help me out immensely with the modification of scanned documents and the ability to fax them...

I tried the software and then cancelled… I tried the software and then cancelled it. For me it was too challenging to use. However they still charged my account for a year up front. I didn't authorize that. I called and requested a refund and they gave one right away, so they said. It was just today I requested a refund so I will check my account in a few days to see if they actually sent it. If you don't see a complaint from me here on Trust Pilot then PDFFiller honored my request. My name is MarioV.

I am not computer techy I am not computer techy - and I have been able to figure this out to do what we need. I am sure there are features that I have not figured out yet - but I stay very busy @ work so doing a webinar would be tricky to schedule.
