Blogger - PDF Filler
Online use without having to download anything onto your computer. If you are a blogger you have too much on your desktop already!
Easy to use. No need to have other software to fill-in your PDFs (contracts, flyers, etc.). This can be used online on any computer. You can even have docs e-signed. There's also a free trial.
I do not have anything bad to say about it. It was easy to use. I will continue to use and refer people to it.

PDFfiller note editor
Overall, it is a good site to use when you need to edit PDF's, especially for classes.
I like how easy it is to upload your PDF on the website by just dragging it into an area that automatically brings it up. When it downloads on the site, you are given so many options to edit the PDF by writing directly on the PDF, attaching shapes, underlining, etc. If the PDF is many pages, all you have to do is scroll through the pages, which makes it very accessible to edit the whole PDF.
Something I didn't like about PDFfiller is the pages of the PDF become a little blurry when it downloads on the site. It doesn't effect the editing options, but it does effect how it comes out and looks.

Haven't used much just for a few document but so far very satisfied. Easy to scan and load to fill in docs. I'm hoping it will be worth the price paid

So far so good
So far so good, i personally like the documents you created are saved on the main screen and I can use it without having to look up instructions.

Tons of functionality for a great price. Excellent customer response time.
Feedback: when using the "home"/"end" keyboard buttons, it immediately takes you to the top/bottom of the form instead of beginning/end of the text box you are editing. Just an unintuitive and weird feature.
Also, it would be great if there was a way to save LinkToFill settings so that they can be applied across other documents.
Overall really happy with this product!

Great for PDF editing
How easy it is to fill out pdf forms and add signatures. Much cheaper than adobe alternative.
I am happy with all aspects of the product.
2023-01-13
Really came through for me when I was charged a subscription fee. Being a small business owner, things get hectic. I had used it for my taxes and meant to cancel it but forgot. They cancelled my subscription and refunded the fee with no questions asked. Too bad it really wasn't a good fit for my business."
