What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I worked fine for my needs of filling in a PDF file and saving it with data. I would like to see the ability to CREATE a fillable PDF file that I could distribute to others to fill out, save, and return to me.

LIKED THE ABILITY TO SAVE AND PRINT BUT IT TOOK SEVERAL TRIAL AND ERROR EXPERIENCES TO FIGURE OUT THE PROCESS. SOMEONE WITH VERY LITTLE COMPUTER EXPERIENCE WOULD FIND THIS FRUSTRATING

I have used it almost every day for over a week to fill out forms. I find it to be a bit awkward at times but I'm getting better at finding my way around. I will continue to use it.

What do you like best?
I like the idea that I can edit a PDF document that is not machine fillable. I have been using this program for several years now in personal and not for profit business.
What do you dislike?
This is not the most user friendly program to use. It lacks a search field or help section to answer questions as how to do something I do not know how to do. It would be nice to be able to save a document as you are finishing instead of having to go back and rename a document. This is the case when I am using a master form that gets updated each month. I work on my laptop and the print screen has the print button to low. I see a sliver of the print button, that if I mess around with it for a while, I can eventually click on it. I can't be the only person with this problem. It would be helpful if the print screen could open a little higher on the screen, reduce some of the preface before the print button or have the print button on the top of the form. I also get frustrated with getting an actual signature in the system. There are no clear instructions on how to do that. It took me hours and hours to get my signature as part of the program. It would be nice to be able to scan a signature into the program. I have used Adobe DC with work in the past and I find it is a superior product, but not worth the cost with the volume of paperwork I need to do. Also a typical example of issues I have with PDFiller is the instruction to take a screen shot of my log in page. I have no idea of how to do that so I attached a PDF master document I use pdfiller to complete each month.
Recommendations to others considering the product:
Don't expect to see the most beautiful documents as far as how things line up, but it is certainly a way to complete PDF forms typed instead of hand written,
What problems are you solving with the product? What benefits have you realized?
As I stated above I use PDF filler with forms that are not fillable. I have used them to complete tax returns when a fillable form is not available. I have used them to sign a document instead of having to print, sign and rescan the document before sending it back to the originator. I have not used it to obtain other peoples signature

Easy to use and efficient Excellent The software is easy to use and the efficiency is definitely worth the price. I would recommend this product to friends and colleagues. I haven't experienced any issues with the product.

PDF Filler is a must for me! I love it! As a small business owner who strives to maintain a professional business image (website, business cards, etc.) , PDFfiller does just that for the proposals I create for my customers ... both future, and repeat. I know for a fact my customers appreciate the quality and professionalism of the proposals they receive from me - they've told me so! Thanks PDFfiller! I love the ability to quickly, and easily, create/copy professional proposals for my customers. I then save each file as a PDF (with my logo embedded at the top left of each document), and attach via e-mail for completing my estimation process with each customer. The only thing I've discovered is with the particular template I use for my particular proposals - my template has an area that indicates "Page 1 of _" ... well, there are no additional pages that are affiliated with my template, so I end up either having to re-edit to ensure my entire proposal fits into "Page 1", or I have to continue additional pages outside of PDFfiller.

Kara, The Support Agent The Support Agent, Kara, that helped me with what I wanted to do was very accommodating and friendly. I had not fully explored the features of this application but I needed to get something rather urgently. Kara was very patient in explaining to me all that I needed to do. I am quite impressed with the Support provided by Kara and by PDFFiller itself.

organization I wish the updates had an option to keep the title and not make duplicates. I like to keep "my documents" organized and not all the downloads unless I want to save it as multiple copies. I love that it combines pdfs w other docs. I love the highlight and annotate features.

Instructions and Help about Unite Sum Document Gratuito

Unite Sum Document: easy document editing

The PDF is a standard document format for business purposes, thanks to its availability. You can open them on whatever device you have, and they will be readable and writable identically. It will open exactly the same no matter you open it on a Mac or an Android smartphone.

The next primary reason is data protection: PDF files are easy to encrypt, so they're safe for sharing data from person to person. Apart from password protection features, some platforms offer opening history to track down those who read or filled out the document.

This web platform integrates with major Arms and allows users to sign and edit documents from Google Docs or Office 365. Use the completed document yourself or share it with others in any convenient way — you'll get notified when a person opens and completes the form.

Use editing tools to type in text, annotate and highlight. Change a page order. Once a document is completed, download it to your device or save it to cloud. Collaborate with others to fill out the document and request an attachment if needed. Add images to your PDF and edit its layout. Add fillable fields and send documents to sign.
