What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
My experience has been wonderful. I paid a lot of money for a divorce site that would allow me to use fillable forms. It was frustrating from the beginning. I started using PDFfiller instead, and requested a full refund from the other service. They refunded my money. I have had great luck finding everything I need for this divorce. Your help support is great! I would certainly recommend this company/service to anyone.

Pretty straight forward but when you want to print multiple forms of the same type I don't see a way to easily clear the info, I have to overwrite or clear each field manually. Thank you, Fred McFaddin

Very smooth and easy. A little set back by only being able to elect monthly or yearly before being able to print, basically buying something you haven't seen. I paid for a year, doubtful I'll use it more than a few times. Would have preferred a "This Time Only" charge. But I like the ease of the product.

I had issues at first as connections failed and I lost my documents that I had updated which took me a long time to do. I have had another go and it has worked a lot better.

What do you like best?
Huge time saver because we spend a great deal of time filling out forms, and we fill out the same forms with the same info year after year, and pdffiller keeps it for us and all we have to do is change the date.
What do you dislike?
Nothing really. It's an odd process, fill in your forms, hit this button, then hit that button, and then go find the finished product in your downloads. I would prefer to specify where it goes and rename it before it goes there.
Recommendations to others considering the product:
If you are an insurance agent that uses Acord forms, this is for you.
What problems are you solving with the product? What benefits have you realized?
This definitely saves me money because it save my staff huge amounts of time. Everything is now done digitally, so we need our forms in a digital format that we can save from year to year and change information in the forms at will.

What do you like best?
The program is user friendly and helps me with the essential tools I need to fill in and change my PDF files. I use this on a daily basis for work and works very well with other programs I use.
What do you dislike?
The font match is the only downside of the program i face especial when I have to fill in words and characters onto the document. It takes time for to match the font that is similar to the original font. Collating pages in a certain order is difficult for me but I decided not to use this feature.
What problems are you solving with the product? What benefits have you realized?
I am facing no problems using the program. The main benefit I use this program is the editing of the documents revived for out business to use for our needs.

ePub is the industry standard ebook file format. Mobi is amazon's proprietary format. Most readers can read ePub as well as other formats, only kindle reads mobi and no ePub. Amazon's kindle previewer program will convert an ePub to mobi, but you'll have to use something like calibre to go from mobi to ePub.
If you're using anything other than a Kindle or the Kindle app, then EPUB is the better format. The only real reason to use MOBI is for compatibility with Amazon's e-reader and app, but otherwise it has no advantages over EPUB, which is a widely accepted format that is much easier to work with.
