I like it but wish there was an edit instead of erase and text to change something. There may be but I'm not aware of it so a webinar would be very helpful.

I am finding it very helpful. I would be interested in learning how to use it better, so a webinar would be helpful. We have a business account and most of our staff do not know how to use it at all yet, so a webinar would be really helpful.

A Great Source for Reference As soon as I came across PDFFiller I immediately subscribed. Any time I need to make a fake document for a Movie or TV show I go right to the site and look up what I'm trying to mimic. 9 times out of 10 I find what I need. I love PDFfiller because it provides me with a wealth of real life uploaded document references for any design I may be trying to mimic. The search feature could be a little better.

What do you like best? We have used PDFFiller for years. I like the ability to use editing tools other apps charge extra for. The ability to use the mobile app was especially useful when we were in a bidding war for the purchase of our home. We were able to edit and sign purchase agreement on the fly. What do you dislike? User interface has not been updated in a while and feels a little clunky. What problems are you solving with the product? What benefits have you realized? We have clients sign documents and contracts. We are able to edit PDFs directly rather than scanning or retyping documents in a word prove easier.

Easily Add and Delete Pages From PDFs PDFfiller has saved me a lot of time combining PDFs and adding/deleting pages. Definitely a must have software. I like that I can easily add and delete pages from PDFs. They also make it super easy to combine PDFs together. Overall, very happy with the platform. Might be nice if there was an option to upload and download to Google Drive.

Great service. I thought my subscription had expired but the tech support hooked me back up in a jiffy! I prefer to use PDFfiller program rather than the Acrobat Reader DC program. I will always renew my subscription in the future.

Provide the required text in the label. Provide a graphic * image in the label with appropriate alt text. Providing a star (asterisk) symbol. Use of color to identify if a form control is required. Providing HTML5 and ARIA required attributes.
Most designers use asterisks to indicate the required fields. But it is necessary to stop, the research on the subject is clear, and it is already the case for quite some time, used asterisks for the required field is a common mistake.
”Field is required” is a flag that has absolutely nothing to do with screens. You either need to remove the flag in the field configuration, making it optional, or you need to add the field to the screen, so the user can obey the mandatory rule you've set.
Mandatory fields are questions that must be answered before the form can be submitted. Mandatory fields are also called compulsory or required fields. The opposite of a mandatory field is an optional field. Optional fields are also sometimes called voluntary fields.
Asterisk (*) next to a form control's label usually indicates it as “required”.
