What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
It's very good the only thing about it is you can't copy and paste because the words will go off the documents also the little box you can type in be off so it makes the documents look odd

Since this was my first experience using this app. I found it to be very user friendly. I am sure it will be simpler with additional experience.
With the second use, this app. is very user friendly.

it's pretty good. sometimes when you edit, it looks like your edits are going to look funky, but when you print it looks alright. I wish it matched the text font and size as the original. You kinda have to hunt around and size accordingly

I wish there were more typfaces I could use. Also, I couldn't figure out how to italicize titles within the document without it italicizing all around it. I gave up after several attempts. Wish that part were more user friendly.

could be better
I feel that adobe does a better job at converting PDFs. Although PDFfiller has a good trial period that you can use all their resources. I like that it has a notary with the plan you choose.
some documents don't fit what you search for. Conversion to PDF could be simple.

Their customer support was one of the…
Their customer support was one of the best I’ve seen. Within minutes my problem was resolved. Kara was very polite and professional. Rare you see customer support like this

Great app, but even better customer service. I needed to cancel my membership for financial reasons, but I failed to do so before it renewed and my bank account was drafted. I submitted a request through the website for support and requested a refund. *** replied via email within an hour and had already issued the refund. Clearly they care about their customers, provide easy communication options and have fair policies in place.

I am a relatively new user to pdffiller, but have found the platform user friendly and does exactly what I need it to. Helping me modernise a lot of statutory requirements for e-signatures and template creations.
When I experienced issues loading documents due to permissions through my work network, the support team at pdffiller responded quickly and continued assisting myself and co-ordinated with my employers IT support function to resolve it within 24 hours, allowing me to get on with my job.

This app is not flooded with ads and/or private tools as far as I could check
I just needed to merge stuff and this website (didn't know it, it just popped after a simple search) showed me tutorials for all the tools they have to make my documents complete and personalized as needed. I am here because we live in an era where an app that does not flood you with advertisement and charge your for each tool available calling some of them 'premium' or 'plus' or 'pro max' is RARE. I want to be explicitly thankful about this. Useful for the purpose of being useful. Didn't believe stuff like this existed anymore.

DID phone numbers used to have letters?

What year did phone numbers have letters?
In the most areas of North America, telephone numbers in metropolitan communities consisted of a combination of digits and letters, starting in the 1920s until the 1960s. Letters were translated to dialed digits, a mapping that was displayed directly on the telephone dial.

How do American phone numbers work?
The standard American telephone number is ten digits, such as (555) 555-1234. The first three digits are the “area code,” which, in the past, indicated in what part of the country the phone was located. If the phone you're calling from is a cell (mobile) phone, then the '1' is not required but the '011' is required.
How do I enter an American phone number?
00 — the exit code to dial outside the States. 1 — the US country code. 202 — the local DC area code. 588-6500 — the rest of the embassy's number.
Are all US phone numbers 10 digits?
In the United States and Canada, ten-digit dialing is the practice of including the area code of a telephone number when dialing to initiate a telephone call. When necessary, a ten-digit number may be prefixed with the trunk code 1, which is often referred to as 11-digit dialing or national format.
