I was frustrated trying to work with another program, then gave up. I found your site on the internet and I am able under a very stress time limit to finish the work and I was pleased with the results.

I would like to attend a webinar at some time, but for next few months I am far to busy to take time and energy for the webinar. I'm sure there is much to learn although I did succeed in working on document that needed to be done. This is a great tool; I look forward to continuing to use it. Thank you!

Nice service, but entering in text into some of the fields can result in wonky formatting if more text than can be displayed is entered. And it's not easy to re-visit the fields and edit/shorten the text.

Easy to use, the functions are very intuitive
Easy to complete documents online and share electronically instantly
Pdf filler is very easy to set up and use. The monthly fee is at a low cost. Using this service makes completing and sharing electronic documents simple and efficient.
It is not free but is a very good value. You can try it for free to see how the program works but if you chose to use it, you will pay a small fee before you can print or send a completed document. Some pdf files are not compatible or are difficult to get the text exactly where I want it.

This is the first app that I found that… the process to combine two files onto one page was simple.
This is the first app that I found that it will actually let you combine two files onto one page simply. The only bummer was that I had to convert the .pdf file into a .jpeg first before I could combine them together.

I used you to arrange a document and I must point out that it was easy to operate and arrange. Very convenient to use and the customer service is pleasant and courteous.

Is there a way that 1 page can be…
Is there a way that 1 page can be flipped? sometimes there are documents that are written horizontally and there is no way to fill it in unless the sheet is rotated. If there is no way to do this then it should be. That is why one star is missing. otherwise great.

Can a flattened PDF be edited?
Once a PDF is flattened, it becomes a single-layer, non-editable document.
What is the purpose of flattening a PDF?
"Flattening" a PDF is necessary to reduce a document's size, if a PDF includes a form, or to meet sponsor formatting requirements. PDFs that are not flattened can create errors when users upload documents to a sponsor's system.
Is flattened PDF format better than editable?
In most cases, Flattened PDFs are recommended due to their smaller file size, compatibility with most PDF viewers, and the ability to make handwritten text searchable, similar to regular text. However, if you wish to preserve outlines or hyperlinks in the exported PDF, opting for the Editable PDF Format is necessary.
What is flattened vs editable PDF Goodnotes?
"Flattened" means that everything becomes one layer and can't be edited, clicked or modified after exporting. If you want to preserve these hyperlinks and outlines in an exported document, set the PDF Data Format to "Editable" in the Export Options.
