What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
So far it has been frustrating ( just because I am not tech savvy) I am just trying to reprint a pay stub that I have lost from a former employer and I just keep running into problems. However after watching a video I figured it out without a problem. Customer service is A1.

What do you like best?
I like that we can search the internet for fillable forms. I also like that we can email and fax right from pdffiller
What do you dislike?
The only issue I have had is when using the iPad or iPhone version. The dates become messed up for some reason. Very simple to fix once I’m back in a computer though.
What problems are you solving with the product? What benefits have you realized?
This allows me to send insurance documents without having to go through multiple websites.

What do you like best?
It is a simple process to upload, fill out typed forms, e-sign, and save/print externally.
What do you dislike?
I have not been able to drag and drop from outlook '07. The additional step of saving a document locally and then uploading seems unnecessary.
Recommendations to others considering the product:
This is a very intuitive product that can one can pick up and become proficient with little training or experience.
What problems are you solving with the product? What benefits have you realized?
I have been able to keep from printing countless documents that only need a quick signature only to be scanned in again and emailed out. There is a huge time saving as well being able to cut out those middle steps.

Easy to use! Service was easy to sign up for and use. There were clear menu bars showing the tools and how to use them to edit my PDF files. Would recommend to others, would keep the service if I didn't already have the full paid version of Adobe PDF I only needed this one time on a computer other than my own or would have continued my subscription.

The only complaint that I have is that… The only complaint that I have is that in the editing section it isn't user friendly. For me I had to just rewrite my whole paragraph since it wasn't easy to just copy and paste! Otherwise I am really pleased with the pdf revise site.Jacqueline Radell- McRaney

If you try to run a general-purpose compression algorithm on something that's has already gone through a specialized compression algorithm (e.g, if you zip a video file), you're likely to get a larger file out. If you want your file both compressed and encrypted, then do the compression before the encryption.
When you compare data compression ratios, it is clear that you must apply compression before encryption otherwise compression will have no effect. The results from my benchmark show the performance as the average number of nanoseconds it takes to complete each operation.
This means the value of compressing data will not exist, as there should be no patterns in encrypted data. Due to this, differential cryptanalysis can be used against this method to determine the sensitive data's value. Compression then encryption is much more resilient to differential cryptanalysis.
Encryption turns your data into high-entropy data, usually indistinguishable from a random stream. Compression relies on patterns in order to gain any size reduction.
