What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I found it relatively easy to use, it would be nice if it had an undo selection. And getting the right size font was not easy. Had to wait for print out to see.

What do you like best?
I started using PDFfiller as an alternative to Adobe Acrobat, which is not available for Chromebook. I expected it to be something I could use to make small edits to PDFs and also to fill in non-fillable forms. It has proven to be way WAY more than that. I like that the program is incredibly versatile
What do you dislike?
I wish I could save files to by Google Drive into the folders that I want rather than having to move them from the PDFfiller folder.
Recommendations to others considering the product:
Try it first, but it really is that good.
What problems are you solving with the product? What benefits have you realized?
editing PDFs, converting PDfs to Power Point, signing documents directly,

This is the only app I can erase and… This is the only app I can erase and fill-in easily so I love it. However, the signing function is glitchy so I use Docu or Adobe sign for that. Still, soooo worth it b/c of the Erase and Fill features.
