What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
The only issue I have is that old documents that I thought would be saved are not. That is my issue, however, and not yours. Everything else is great.

User friendly. In past years I've been able to bring up the forms I need from www.irs.gov and fill out the forms, save and print the forms. Same is true for Louisiana Dept of Revenue. Now neither of the websites supports filling out any forms. I was extremely frustrated with this change. PDFfiller has made my life so much easier. Thank you

I needed PDF Filler (or something like it) for a specific purpose and for a short time. It got the job done.
I was surprised to see the Annual Fee ($72.00) show up on my credit card statement, instead of the monthly fee ($6.00).
I cancelled my subscription on 4/11/2016, and have been checking my statements for a refund. Am I waiting in vain?
2016-06-05
It would probably be a big plus for most. I have been this job for 13 years and I'm so used to it as well as my clients being used to me. It just works to handwrite them for me. It is easy to use, it just takes longer for me to do.
Great product, reasonable price.

The go-to for creating useful PDF files
This software has become a go to for pretty much every PDF file I have to create. I have used it to create forms that our midsize business uses on a daily basis. I find it to be very user friendly and a quick and easy way to get what you need. It has positively affected our costs of printing and paper, and it's good not only for our budget but for the environment too!
Customer service is not the fastest and sometimes I have a question that needs to be resolved that day. I read online that it depends on the plan you have purchased and I don't think that is the best way to treat your customers.

Makes forms easy
Easily able to make fillable forms for PT's, Able to edit pdf's easily
There are times when it will make multiple copies of documents
2019-07-20
What do you like best?
It is user friendly, very easy to navigate and to find the features I need regularly such as text and erase
What do you dislike?
Nothing that stands out. Again I use it every day and it has greatly reduced time spent on admin work
Recommendations to others considering the product:
It's worth the investment
What problems are you solving with the product? What benefits have you realized?
I have many forms sent to me (employee evaluations, intern evaluations) that are in pdf and pdf filler has been an affordable way to turn those forms around quickly

Great customer service. My Employer needed a form off their website, and he had signed up for the subscription, the following month his credit card **** was almost a thousand dollars- so, myself, the office manager, I knew my boss only needed the one form he went on the website for, I went on the site,started talking to a live help agent, (very nice and helpful) I explained the situation, was asked basic information, and was told within 5 to 7 days the refund would be back to my boss's institution. Without any issues, or problems. This company is very helpful and has GREAT Customer Service! 5 stars plus! thank you!

What is the formula for resolution?
Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 (where is the standard deviation) and the peak FHM is W0. 5h = 2.354.
How do you calculate the resolution of a microscope?
NA= n x sin Where n is the refractive index of the imaging medium and is half of the angular aperture of the objective. ...
d= /2 NA. Where is the wavelength of light used to image a specimen. ...
d= 2 /NA2 ...
R= 1.22 /Naomi+Second.
What is the limit of resolution of a microscope?
The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object. It is the distance between two points in the object that are just resolved in the image.
How can the resolution of a microscope be improved?
The resolution of a specimen viewed through a microscope can be increased by changing the objective lens. The objective lenses are the lenses that protrude downward over the specimen. Grasp the nose piece. The nose piece is the platform on the microscope to which the three or four objective lenses are attached.
How do you know if a microscope has a good resolving power?
The resolving power of an objective lens is measured by its ability to differentiate two lines or points in an object. The greater the resolving power, the smaller the minimum distance between two lines or points that can still be distinguished. The larger the N.A., the higher the resolving power.
What is light resolution?
Resolution is the amount of detail you can see in an image. ... In a compound microscope, the wavelength of the light waves that illuminate the specimen limits the resolution. The wavelength of visible light ranges from about 400 to 700 nanometers.
Which light is suitable for maximum resolution?
Light Wavelength and Refractive Index Near-ultraviolet light has the shortest usable wavelength and offers the greatest resolution. Following near-ultraviolet in descending order of wavelength are red, orange, yellow, green, blue and violet.
What affects the resolution of a microscope?
The primary factor in determining resolution is the objective numerical aperture, but resolution is also dependent upon the type of specimen, coherence of illumination, degree of aberration correction, and other factors such as contrast-enhancing methodology either in the optical system of the microscope or in the ...
What is the resolution of a light microscope?
The maximum magnification of light microscopes is usually ×1500, and their maximum resolution is 200 nm, due to the wavelength of light. An advantage of the light microscope is that it can be used to view a variety of samples, including whole living organisms or sections of larger plants and animals.
How do you find the lateral resolution?
Lateral resolution is approximated by the 6 dB full-width half-maximum beam profile, given by LR = 0.4 × A F/L, where LR is the lateral resolution, is the ultrasound wavelength, F is the focal depth, and L is the active aperture length [20]. So, the greater the aperture, the better the LR.
