What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
The features are great. It would be nice to have the option to combine PDF documents. I also have an issue when entering text where the text box disappears and I have to click on the document again to enter text. Aside from that, he existing features are great and I would like to see how PDFfiller can improve in the future.

What do you like best?
I like that you can save the template for a certificate of insurance or an application and send it out that way. It still saves it as new but also creates the new Document.
What do you dislike?
The same feature that I love so much, isn’t quite as easy to navigate on the App. It’s super easy on the full online version though.
What problems are you solving with the product? What benefits have you realized?
Super easy to use on the go with the App access. I live that part of it.

Review of PDFfiller I like this software. It makes the process of editing and filling out pdf files faster, especially when it comes to long documents. It's definitely worth trying. My only con is that sometimes the program freezes and I need to restart it.

I think 40 dollars is too much, but... I think 40 dollars is too much, what you offer is well worth it except for the fact that it's a service I would only use occasionally. So 40 bucks every month is way too much for me. But I do love what you offer.

I initially thought that PDFfiller was a free tool. Even though they asked me for my credit card information with a free 30 Day trial I forgot about the same. When I got an email a month later stating I had been charged for the whole year I logged in and chatted with Customer Service. They were so kind as to immediately understand, cancel my subscription, and agree to issue me a refund. At the time of writing this, I am still awaiting my refund as I just requested the cancellation today - but I must say that this gesture was amazing by PDFfiller and this review is the very least I can do. Thank you for brightening up 2020 a bit! Amazing business ethic and professional courtesy.

How to set a password to protect PDFs on Android. Begin by navigating to the password protection page on your preferred browser. Click the Select A File button to choose and upload your PDF. Create a password and enter the password, then retype it to confirm.
Open the file with the right password. It's very easy to open password-protected PDF documents even on Android if you know the password. Any mobile PDF readers worth their salt support passwords and can unlock the files. Simply open the PDF document and enter the password when your Android device prompts you for it.
Yes – but only with a PDF DRM solution like Safeguard Security. Though you can encrypt the file before emailing it, it won't protect the document after it is opened on the other end. The user would still be able to copy and share the decrypted PDF file.
