What our customers say about pdfFiller

Just started using the program today. Easy so far. A little problem with the aligment of fields. It would have been great to use the "tab" key to toggle between fields.

The log in process is a little clunky. I have not been able to copy paste a field in the template creator. I have 30 fields or so that will each have the same sized field, I should be able to duplicate the specific field a number of times and paste. No?

I own a few franchise restaurants and have to use this product about once a week and it makes my time with documents way faster and easier. I don't have to download a document, scan it, sign it, and then rescan it and then send it. I can do it all electronically thanks the PDFfiller.

Thanks for the one-time use
You acknowledged that people need a one-time use for. While this site was great, I don't need it in the near future. You made cancelling the subscription easy and not a giant maze of site's you need to navigate through.

Does flattening a PDF make it Uneditable?
Flattening the layers combines them into a single layer, making them no longer editable independently. Similarly, an editable field in a PDF is simply another layer that the PDF format supports, and they can be flattened to make any entered contents static.
What does it mean to flatten file?
When you finish editing all the layers in your image, you can merge or flatten layers to reduce the file size. Flattening combines all the layers into a single background layer.
Should I flatten my PDF?
Flattening a PDF is necessary to reduce a document's size, if a PDF includes a form, or to meet other sponsor formatting requirements. PDFs that are not flattened can create errors when users upload documents to a sponsor's system.
