I have used PDF filler a couple of times and so far I love it! Just a little suggestion, maybe you can add/give the option to be able to change the size of the fonts without having to add a text box where there is already one to fill (does it make sense?). Thank you!

There was one issue- the orange pen would pop up when highlighting a word or sentence, suggesting an edit I assume. I would click it then stare at a blue circle waiting waiting waiting. I would just close the entire website and come back.

Excellent tool, very useful and easy to use In my work we use a lot of PDF for contact with the client and the truth is that it is useful to have such a tool to make it quick and easy; It's something less to think about. The best thing about this tool is that it solves a basic problem with the PDFs we receive: editing them. It is also very easy to use, saves a lot of time and has the possibility of adding a digital signature to each document. Some form formats are more complex to edit and the tool gets confused, but it happens with all other tools.

Handy programme for the home office I'm still getting used to all the available functions, but so far am enjoying being able to combine various documents, and edit and sign .pdfs

What do you like best? Ease of use and the editing tools available. What do you dislike? It would be great if the system would take me straight to the My Docs page at login. What problems are you solving with the product? What benefits have you realized? Great for needed digital signatures on contracts, etc. We also use it to edit maps we use in our business for clarity.

New to this software but appears to be want I needed working with the many aspects of PDF's for our website. PDF Filler offered an excellent annual rate. I am concerned a little about getting to involved with them. You see it happen often after one year with service providers the rates start increasing. Than you need to find a new service to merge your existing business with. We'll see. Overall though the company has been excellent.

Why you should choose pdfFiller

The fundamental functionality of a good PDF editing platform is to create, edit, share and convert documents in a fast and effective manner. A PDF editing tool should be able to convert your documents into various file formats in order to use them in any other program. Yet there are many platforms offering this functionality, most of them are limited or provide it as a paid feature.

Nowadays, most users won't use a program or website to just change some text in a document — they need a multi-purpose tool to make a workflow fast and efficient. From document creation to placing a digital signature on it, you'll need a solution that does it all in a single browser window.

pdfFiller is a browser-based fully-featured tool which allows you to produce, edit, sign and store documents across all of your devices. In addition, it’s cloud-based which means that your documents are safely stored in the cloud and can be easily accessed by you, your teammates, or anyone who has a permission, simultaneously.

With pdfFiller, you're able to:

01
Create professional documents on your own: business, tax, legal, etc.
02
Get a cloud-based mobile application for iOS or Android
03
Discover the library of over 25 million ready-made documents
04
Distribute forms via QR Code or hyperlinks through email, SMS or social media
05
Discover numerous integrations with Google Drive, Dropbox, OneDrive and more

pdfFiller keeps things simple while at the same time providing you with a full suite of editing features: highlighting, redlining, fillable fields, signing and much more. We might be biased, but we know users tend to choose pdfFiller for many reasons.
