Free Redaction Tools: A General Overview

Now that we’ve reviewed the free redaction tools from, PDFfiller, PDF Buddy, and AvePDF online, it’s essential to note that these platforms all share the following limitations:

  • Manual Redaction

Most free redaction tools online require you to manually select each occurrence of the sensitive information you want to remove from your document one by one.

If your redaction needs only extend to a page or two per day, these tools may suit your purposes. However, for organizations that handle larger volumes of sensitive documents that might contain tens or hundreds of pages, manually redacting every instance of sensitive data is time-consuming, expensive, and prone to human error. Once redaction has been applied, there is no way to ensure that all sensitive data has been eliminated without multiple people reviewing the file to ensure that nothing has escaped the redaction process.

  • Security

You need a highly secure redaction tool to meet your redaction needs if you deal with large organizations that handle sensitive data, such as government bodies, healthcare providers, court systems, law firms, and HR departments.

Using free online redaction tools poses significant risks to data security, as these platforms may not always securely handle or delete sensitive information, often lack encryption, and could even retain data after deletion. Many such tools do not employ proper redaction techniques, potentially allowing sensitive data to be uncovered. Additionally, these tools can be exploited by malicious actors to steal information, do not always offer accountability if data is compromised, and may not comply with strict data protection regulations like HIPAA or GDPR.

Why is Redactable a better option?

The service provided by free online redaction tools may be adequate for casual or personal use, but when it comes to performing redaction in the course of business, you need a more serious tool.
