PDFFiller saved my books! PDFFiller saved my books! As a young author, I had no idea what I was doing and deleted my original documents once the books were published. I only kept the print-ready PDFs. Years later, I realized there were a lot of spelling mistakes and errors in them, and wanted to re-publish. Since the books had photos, I couldn't simply convert to a doc. Most PDF tools online didn't work, or put on watermarks. PDFFiller allowed me to edit the text in the PDFs, to correct the spelling mistakes, and merge the documents into one cohesive PDF again. I was able to republish an edited book without the original documents, thanks to PDFFiller. The one thing I missed that could make this a fantastic tool- the original book was 8.5x11. I wanted to republish at 6x9. I ended up having to resize it through a different tool, which simply shrunk everything instead of being able to directly resize the content. Due to that, the book appears much smaller on the pages than it should, and I've received some complaints that it's harder to read. If PDFFiller had a viable PDF resize tool that worked to resize the content versus simply shrinking the document, it would be a stellar addition to the repertoire.

It's been a life saver in a lot of situations It's versatile and sleek and does just about everything that I need when working on PDF documents. I've loved having to school use as well. I wish that I could merge and split PDFs instead of just write on them. I also think it would be great if PDF filler had a better way to see where documents are in the signature process.
