PDF Filler is great. However, I wish it had some photo cleanup like features. For instance the ability to white out, or clean up shadows, or dark areas, while leaving all printed in black areas in tact.

Effortless Document Filling with pdfFiller! Overall, pdfFiller has been a great tool for me. It's saved me so much time and hassle, and I'm really happy with the results. Highly recommend! I've been using pdfFiller to fill out documents for a while and I have to say that I'm very impressed with its ease of use! It's incredibly straightforward and makes it so easy to fill in the blanks on forms. Plus, they have a wide selection of templates that make my job even easier! The only downside to pdfFiller is that the free version has some limited features. If you need more robust features, you'll have to upgrade to the premium version.

Can't Wait to Convert So far I am just playing around with things to figure out how everything works. I've used pdfFiller as a signer before but never in any other capacity. I'm looking forward to being able to covert PDF's to Word documents.
