sometimes when i save my pdf everything…
sometimes when i save my pdf everything is out of alignment. even though in the preview everything is in place. when i save it seems some lines and words are shifted
Excellent easy-to-use online file editor
Super easy and practical tool. Without a doubt the best I could use. It makes my tasks much easier in my work area allowing me to edit documents quickly.
PDF FILLER is a great editor. It allows me to make changes to my documents, files and easily save them on my computer making my work much easier.
One of its disadvantages is that to be able to use this software it is essential to have an internet connection since it is a service that implies having a user and opening a session.
It's diffcult to make some changes or fix mistakes. I have notice that it is had to find a blank form. So if you need to file say 2 941 forms. I couldn't just choose another 941 form from menu. I had to use one of my saved forms or let the site and choose to file 941 and log back in
This has been a lifesaver for me
This has been a lifesaver for me. I have several contracts with jobs that I am doing. To be able to fill out contracts, questionnaires, job interview questions and send project proposals has been amazing. THANK YOU FOR THIS APP!
