I was in a jam! Law School needed me to fill out three documents and sign them and return. The only problem was that I did't have a fax, or scanner. With PDF filler I accomplished my mission at a fraction of the time and cost.

This is a tool which I never thought I would use so much! I love it! I think the dashboard is cluttered and not the easiest to navigate, and a "strike through" option for documents would be nice to have.

PDFfiller is a good value application for PDF file editing, filling and file management. My limited use of the application so far leaves a lot of its functionality to be discovered. However, it is very user friendly and simple to work with.

Fast, helpful assistance from their support team I forgot to cancel my subscription with them. The money came out unexpectedly, and I was honestly pretty worried because it was the full year's subscription and I have had issues with internet companies not wanting to refund subscription fees in the past even when I asked for it immediately, without using it during the period I asked for the refund for. PDFFiller was great, though. I emailed them early this morning (late for me) and woke up to their response, which was that since it was less than 24 hours after the payment came out, they were able to just void the transaction. Assuming my bank is cool about it, I'll have my money back today.5/5 Do trust.

Sam, on-line support did a great job! I was very happy that Sam at the On-line Support, came on very quickly and helped me with what I needed and waited until I was sure it worked. I was also very happy that the program did "not" shrink the size of the words in the document like many other programs I have tried.

An effective strategy: draft a checklist based on compliance requirements to guide your redaction process and cross-check your documents before sharing or filing.
Free tools for redacting in PDF documents often come with significant limitations, such as insufficient security features that may not adequately protect sensitive information. They may also lack advanced functionality such as permanent redaction, meaning the sensitive content could potentially be recovered. For optimal results, it's advisable to invest in a comprehensive solution like pdfFiller that ensures secure redaction. A practical consideration: evaluate any free service's redaction capabilities by testing them before use with sensitive information.
When selecting a tool to redact in PDF documents, prioritize features such as robust security protocols, user-friendly interfaces, and the ability to batch-process documents. Tools like pdfFiller also offer automatic text recognition and detailed audit trails, which enhance document management efficiency.
