10 Best PDF Remediation Tools of 2025

PDFs are one of the most convenient and widely used file formats across industries. Yet, despite their popularity, accessibility remains a major challenge. Over 90% of PDFs today are still at least partially inaccessible, often appearing blank, blurry, or unreadable to individuals with disabilities. With trillions of PDFs in circulation, this presents both a compliance risk and a lost opportunity for inclusivity.
Making PDFs accessible is essential to meet standards like WCAG, PDF/UA, and Section 508, and to potentially stay out of legal trouble. Fortunately, advancements in PDF remediation tools have made the process far more efficient. Reports show that automated remediation can save up to 80% of document processing time, reducing costs from dollars per page to just cents for large repositories.
In this article, we highlight the 10 best tools to remediate your PDFs in 2025, ensuring your documents are accessible and compliant.

How to Choose the Right PDF Remediation Tool/Software?

With so many PDF remediation tools available in 2025, selecting the right one can feel overwhelming. The key is to evaluate your organization’s size and compliance needs before investing. Below are the most important factors to consider when choosing your right PDF remediation tool:

Define Document Volume

Start by understanding the size and type of your document workload. Organizations handling thousands of PDFs or complex file types like forms, tables, and scanned images need PDF remediation tools that support batch processing and advanced automation. On the other hand, smaller teams working with simpler documents may find lightweight solutions sufficient.

Determine Essential Compliance Standards

Accessibility regulations vary depending on region and industry. Whether you must meet WCAG 2.2 AA, PDF/UA, ADA Title II, or Section 508, it’s crucial to select a tool that aligns with your regulatory landscape. If your organization undergoes regular audits, look for tools that provide detailed compliance reports to simplify record-keeping.

Evaluate Control Needs

Not every workflow requires the same level of automation. Some teams prefer remediation tools that offer 90 to 95% automation with AI-based tagging, while others may need manual control for precision. Features like built-in accessibility checkers, real-time validation, and guided workflows can help balance speed with accuracy, especially if you’re still learning how to remediate your PDFs.

Think About Integrations

The right tool should fit seamlessly into your existing technology ecosystem. Look for features like API access, cloud vs. on-premises deployment, and compatibility with learning management systems or content management platforms. Collaboration features such as multi-user access, version control, and project management can also improve efficiency across teams.

Consider Budget & Licensing

Pricing models for different PDF remediation companies and tools vary widely. Some may follow a pay-per-document model, while others may cater to enterprise-level licenses. Consider whether the tool can scale as your accessibility requirements grow. A cost-effective option today should not limit you tomorrow if your document volume or compliance needs increase.

Look Into Security & Data Protection Requirements

If you work in industries like healthcare, finance, or government, a tool with strong data protection standards is non-negotiable. Look for encryption in transit and at rest, SOC 2 or ISO certifications, and compliance with regulations like GDPR. Enterprise-grade security ensures that sensitive information stays protected throughout the remediation process.

Availability of Support & Training

Even the best PDF remediation tools require proper onboarding. Evaluate whether the provider offers documentation, tutorials, live training, or direct support channels. Some even provide accessibility academies or dedicated experts to ensure smooth adoption. This is especially helpful if your staff is new to the remediation practices.

Take the Trial & Evaluation Route

Never invest without testing. Most top tools provide free trials or demos, allowing you to benchmark performance in terms of speed, ease of use, and compliance accuracy. Run real-world tests on your own documents to see whether the tool delivers the results your organization needs.

Base Your Decision on Industry Needs

Finally, match the tool to your specific industry requirements. A university may prioritize LMS integration, while a financial institution may demand high-volume transactional document support. By aligning your choice with sector-specific needs, you’ll ensure your investment in a PDF remediation tool pays off in the long run.
