What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
As a Realtor I am constantly having to merge PDF files, or fill in forms, or add notes to contracts, or rotate pages from horizontal to vertical. My hand writing is not very legible, but PDFfiller makes all of my docs look professional.

After using many other PDF editors finally a user-friendly, is fast, does not freeze and gives me any problems login in or crashing after I purchased.

So far, it is excellent for moderately tweaking content. It would be nice if I could select images and move them like Adobe but this is so rarely needed....

What do you like best?
Easy to use but comprehensive options for editing. Quick and efficient which is important with time sensitive docs and a busy life. Some recent new features tells me the company is progressive. I was having technical difficulties one day and support was responsive. I've tried numerous PDF/Editing programs. and this is by far my favorite. It's web based not some ap that you have to download that later crashes your computer. Can access it from any PC so that helps too.
What do you dislike?
The price is substantially more that I'd like to see. Takes a bit to save file to PC once done editing. can be a little slow at times but still a reliable tool I use at least weekly if not daily. Something in the $50 range would be delightful and it's well above that currently. Maybe efax for this price I have not used the esign feature yet so maybe will try that given our member benefit program is lapsing.
What problems are you solving with the product? What benefits have you realized?
Quick way to edit and correct documents. Easy to save and access later. Lots of options for composing sending and revising. I only use basic functions but there are several ways to use this valuable tool beyond the features I use that exceed other competitors.

What do you like best?
I can remove text with the delete button rather than having the use the eraser tool
What do you dislike?
If I delete all of the characters from a text box, I have to put a space for it to stick; I can't add or drag in other pdfs to merge them. I have to merge them using a separate tool.
Recommendations to others considering the product:
Inexpensive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Redacting resumes in PDF form. Easy to fill out forms as well as it recognizes what the form is asking.

Meralis Acevedo Meralis AcevedoI was able to find the form I needed. The only thing is that it was a little difficult figuring out how to use all the features it has. How to modify the text was not something I was able to do through erasing. Maybe using PDFfiller more often will help me maneuver the site with time.

Filling out Veteran forms made easy This PDF filler is so efficient and easy to learn. I help so many veterans with their forms and always had to print them out and fill them out myself. Thank you for helping me help them and others that cannot fill out forms on their own.

Works Perfectly! I don't typically need a lot of editing, but what I do need this service does perfectly. No guessing about what you need to do like with some other apps, and although I do sort of enjoy the uncertainty of wondering whether things will actually edit or not pdfFiller has definitely helped me be more productive.

It's great It's great. Not as good as adobe in the areas of text replacement or image addition. It is also not as sophisticated for selection mechanisms. If you need to fill in documents or create PDFs this is a solid application that can do the stuff that you will need quickly and cheaply.

Crack growth rate is defined as crack extension per cycle, the/DN. The crack growth rate is obtained by taking the slope of the crack growth curve at the crack length, a, as shown in Figure 2.
(11) and the ASTM standard E399 that measures plane-strain fracture toughness. The equation used by the above ASTM standard to calculate the crack length is [1](20) a/W=0.99973.95U+2.982U 2 3.214U 3 +51.52U 4 113.0U 5 where(21) U=1/{1+[(ABV m /P)(4W/S)] 1/2} and Vm is the COD.
Regrouping gives the critical crack size for a given applied tensile stress: SCR = NCR/Y(c)0.5. The critical crack size, the largest flaw survives for a given applied stress is: Max=(NCR/Is)2. Once the critical stress is reached, fast fracture occurs with the upper limit of the crack tip velocity the speed of sound.
In addition, crack length can also be measured by using an optical microscope, an optical grid technology (Gucci et al., 1972, Must et al., 1976, James et al., 1981), an acoustic emission method (Gautama et al., 1994) and an ultrasonic method (Ahumada et al., 1983).
Note that the stress concentration factor is a function of the geometry of a crack or notch, and not of its size. As the radius of curvature approaches zero, like the tip of a sharp crack, the maximum stress approaches infinity and therefore stress concentration factors cannot be used for a crack.
A crack growth equation is used for calculating the size of a fatigue crack growing from cyclic loads. The growth of fatigue cracks can result in catastrophic failure, particularly in the case of aircraft. Fatigue life can be divided into an initiation period and a crack growth period.
Crack growth stability is called the resistance curve, or R-curve. For brittle materials, is a constant value equal to. For other materials, increases with increasing.
Pubs are areas that rise above (extrusion) or fall below (intrusion) the surface of the component due to movement of material along slip planes. This leaves tiny steps in the surface that serve as stress risers where fatigue cracks can initiate.
