What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Easy and intuitive to use - could fill out forms right away with little effort. Signature capture using the laptop camera did not work - the signature ink lines not clear after cleaning up the image. I scanned my signature at 300dpi using a scanner, and saved that image.
I tried this, liked it, and bought 1 year subscription.

I really love this program - saves me SO much time because I can merge documents or remove pages, along with making changes and corrections. SO much better than rescanning documents!

Fantastic customer service
For some reason I needed this and only once. I got the free trial and then forgot all about it until $115.00 was collected from my account, shock horror. All I can say is you have fantastic customer service, I explained my situation and a refund was issued that same day. Both friendly and speedy. Ace by name and by character, much appreciated. 1 star deducted as I would have liked a reminder email when the free trial was coming to an end.

Support is good but last release is bad
I am really fond of their support team. They are very friendly and provide all help the can. But that's not enough for good product. Support can't fix bugs or make it good for tablets. Try harder.

PdfFiller is one of the better pdf apps that I've used in some time. I was especially impressed with how it handles pictures/logos that one might use in a document.

Perfect for merging multiple JPG images into a compact PDF
This app / web page allowed me to easily merge six JPG image files (each 2550x3300 pixels, some included photos) into a single compressed PDF document that was small enough (7MB) to be easily shared as an email attachment. Did exactly the job I wanted it to!

How do you calculate sealing force?
To determine the force required for proper sealing of a device, the force per centimeter can be multiplied by the overall length of the boss around the perimeter of the device. Specifically, we are interested in the response to the membrane at around 0.4 strain of the boss into the membrane.
How much force does it take to compress an O ring?
The expected range of force needed to compress an bring 20% with a 0.070 diameter cross-section (purple) that is 50 durometers is between 4.5 and 14 pounds per linear inch.
How do you size an O ring?
Place the O-ring on a clean, flat, level surface. Determine the inside diameter. To measure the outside diameter, use a ruler or calipers to measure from one outer corner of the O-ring to the other outer corner. Measure cross-section.
What is O ring squeeze?
What is O-ring squeeze. The squeeze is a ratio of the amount of deformation applied to the seal expressed as a percentage of the free-state cross-sectional thickness. This contact force blocks the passage of liquids, gases, and dry powders, preventing them from flowing between the rubber seal and the mating hardware.
How do you calculate an O ring squeeze?
Find your o-ring's squeeze amount in inches by subtracting the gland depth from cross-sectional diameter with a calculator. For example, if your o-ring's cross-sectional diameter is 1.25 inches and its gland depth is 1.20 inches, subtract 1.20 from 1.25 to determine that the o-ring is able to squeeze out a total of.
How much crush Should an O ring have?
must be smaller than the piston groove diameter, so that the O-ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications.
How do you measure an O ring groove?
Use a little grease to hold 3 or more balls in the groove and use the gags. It's possible to measure deeper grooves by grinding a flat on the balls to allow them to fit. You don't measure the groove, you measure the o-ring. Then machine the groove to give the desired amount of crush.
What is a pressure sealer?
Pressure Seal is a system comprised of a one-page self sealing document and / or a folder / sealer for sealing the document. The form is sealed through a process of folding the form on a pressure seal folder / sealer.
