What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
All of my forms have looked super professional, and when I applied for my new job, the HR department thought it was going the extra mile to type out my application instead of handwriting it.

When I had a deadline to meet and needed to get a series of pdf documents ready ASAP, I was able to use the template feature to save certain information to all docs at once and just fill in the info that differed. This allowed me to meet my deadline and send each completed form with password protection so the client knew I took his privacy seriously. Thank you, PDF Filler, for providing this great platform!

What do you like best?
PDFFILLER has been one of the best platforms I’ve used in client document transmission. The price is unmatched for the services available and the HIPAA compliance seals the deal.
What do you dislike?
The only downside is how long some forms such as registration can take to complete when adding in the initial fillable fields.
What problems are you solving with the product? What benefits have you realized?
Many of my clients are throughout the country, so the ease of securely transmitting documents while maintaining HIPAA compliance is the best problem solved. I recently discovered the ability to have documents faxed digitally through the services and it’s cut down on my physical paperwork.

PDF filler works great and has helped print some documents that we used to have to type.
Less time spent on creating forms for the clinic.
Document creation - used it for paper billing, in house forms, and staff checklists. Easy to create the document and implement
Alignment is sometimes different on the document than what prints. Can take a little trial and error to make it align perfectly.

What do you like best?
I encounter a lot of reasons to amend, annotate, merge, separate, and complete PDF documents. I used the free version of pdfFiller for a while and realized that I used it so much and liked using it so much that I actually paid for the upgraded version. I have been using pdfFiller for about a year and it is a go-to part of my toolbox for document management. In fact, I just grabbed a couple of model forms from my trade association and (with permission) stripped off their information and inserted my firm info and logo. In 15 minutes I had professional forms tailored to my business - I cannot even estimate how much that saved me in time and money. pdfFiller makes me look good, so I am giving them a review to make them look good - it's what I can Good Business quid-pro-quo.
What do you dislike?
Nothing is perfect, and while I gave pdfFiller the highest rating I could, it too is not perfect. I have found that scrolling through documents I have edited rather than being able to create folders to store my completed documents is slower than I want. I come from a Windows environment and have become spoiled by the Windows' file structure. Still, this is probably more about me than about pdfFiller.
What problems are you solving with the product? What benefits have you realized?
I annotate, merge, duplicate, and complete more pdf forms than I like. Most are government or bureaucratic forms and they insist upon too much information. It helps to have forms done one and stored on pdfFIller that I can access to update the dates or other data and resubmit.

Feature filled and easy to use.
I've had an overall great experience using PDFiller. The variety of features gives me the convenience to edit my documents, save them, upload them to my account and allows me to easily send them by email to be signed.

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 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.
What is the resolution of a compound microscope?
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. The best compound microscopes cannot resolve parts of a specimen that are closer together than about 200 nanometers.
What is the limit of resolution?
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.
What is Abbé's equation?
Abbé's equation. This is the diffraction-limited resolution of an optical system. If all aberrations and distortions are eliminated from the optical system, this will be the limit to resolution. If aberrations and distortions are present, they will determine the practical limit to resolution.
What is Abbé's Law?
Abbé's principle relates to accuracy when measuring dimensions. This principle states that, “In order to improve measurement accuracy, the measurement target and the scale of the measuring instrument must be placed in a collinear fashion in the measurement direction.”
What is Abbé's diffraction limit?
The Abbé diffraction limit for a microscope is called the numerical aperture (NA) and can reach about 1.41.6 in modern optics, hence the Abbé limit is d = /2.8. To increase the resolution, shorter wavelengths can be used such as UV and X-ray microscopes.
