Best tool with advanced features - PDF Filler
Add, edit, share & highlight option in one application. Easy to use and must have application if you publish documents frequently.
If you work on PDF files daily it is a must have application. It handles PDF files and let you edit and add content very easily.
- Easy to use tools
- Add text, edit text, highlight, notes etc. many features in one application
- No watermarks which makes it easy to edit and share.
It is working good till now and not found any such cons in the application. Conversion of files do takes times and using advance features needs a pro in that. It gets slower with big files.

This was pretty easy to use once I started. I only needed it for one form and do not edit a lot of PDF files normally.

If it were possible to drag and drop email addresses from my email to the pdf filler I believe it would be easier. I'm writing them down currently and then typing in the information.
2020-12-01
PDFfiller is very customer focused. When I emailed them they responded immediately and followed up with me to assure my questions were answered. I would highly recommend this company.
2020-06-04
Twice a year I need to turn a pdf form into a fillable form. I don't need a subscription for such a minimal need. I wish there was truly a free way to do this without creating a trial subscription.
