What’s new in iLovePDF Desktop for working with large PDFs?

iLovePDF Desktop  is now faster and more reliable when working with large PDFs, with improvements to reading performance, secure redaction, IT deployment and digital signature validation.

Working with big PDFs can be frustrating: slow loading times, lag when scrolling or uncertainty around sensitive information. These are everyday challenges for teams handling contracts, reports, scans or invoices at scale.

That’s why we’ve introduced a new set of updates in iLovePDF Desktop, focused on making large PDFs easier to manage without compromising security or control. From faster rendering and a more reliable PDF Reader to permanent removal of sensitive information and simplified deployment for the IT team, these improvements are designed to support real workflows.

In this article, we’ll walk through what’s new, why it matters and how each update helps teams work more efficiently with PDFs - including digital signature and certificate validation.

Permanent removal of sensitive information from PDFs

What does “permanent removal” of sensitive information from a PDF mean?

It means deleting sensitive content from a PDF in a way that it cannot be recovered later, even by inspecting hidden layers or metadata.

When people ask “how do I permanently remove sensitive information from a PDF?”, they’re usually worried about more than just what’s visible on the page. Simply covering text or applying visual redactions isn’t enough, sensitive data can still exist beneath the surface.

Why is visual redaction not always enough

PDF files often contain hidden elements that aren’t immediately visible but can still expose information if the file is shared or reused.

This can include:

• Hidden text layers
• Embedded metadata
• Content that can be revealed by copying or extracting text

For teams handling contracts, invoices, reports or documents with personal or financial data, this creates a real risk - especially when PDFs are shared externally or stored long term.

How iLovePDF Desktop removes sensitive information permanently

With iLovePDF Desktop, you can permanently remove sensitive information from PDFs so that deleted content is fully erased from the file, not just hidden.

This means:

• The information cannot be recovered later
• The file is safer to share externally
• Documents are easier to manage in compliance-focused workflows

You can learn more about how permanent removal of sensitive information works directly in iLovePDF Desktop.

When does this matter most?

Permanent removal of sensitive data is especially useful when:

• Sharing documents with external partners or clients
• Storing PDFs for long-term archiving
• Working with legal, HR, or financial documents
• Ensuring compliance with data protection and privacy standards

Key points

• Permanent removal deletes sensitive PDF content completely  
• Visual redaction alone may leave recoverable data behind
• iLovePDF Desktop helps teams securely remove sensitive information and reduce the risk of data leaks

macOs signature and certificate validation

How can you verify digital signatures and certificate trust on macOS?

On macOS, iLovePDF Desktop allows you to verify digital signatures and validate certificate trust, helping ensure PDFs are authentic and suitable for secure, legally binding workflows.

When working with signed documents, it’s not enough to see that a PDF “looks signed.” What really matters is whether the digital signature is valid and whether the associated certificate can be trusted, especially in professional, legal or compliance-driven workflows.

Why digital signature validation matters on macOS

Digital signatures help confirm that:

• A document hasn’t been altered after signing
• The signer’s identity can be verified through a trusted certificate
• The PDF can be relied on in formal or legally binding contexts

Without proper validation, it’s difficult to know whether a signed PDF can truly be trusted, particularly when documents are exchanged between teams or external partners.

How iLovePDF Desktop supports signature and certificate validation

With iLovePDF Desktop on macOS, users can verify digital signatures and validate certificate trust directly within their PDF workflow.

This allows teams to:

• Confirm whether a digital signature is valid
• Check the trust status of the associated certificate
• Review signed PDFs without relying on external tools

These capabilities are designed to support secure and legally binding PDF workflows, while keeping the validation process simple and accessible.

When this is especially useful

Signature and certificate validation on macOS is particularly important when:

• Reviewing contracts or legal agreements
• Handling signed financial or compliance documents
• Verifying documents received from external parties
• Ensuring document integrity before approval or storage

Key points

• iLovePDF Desktop lets you verify digital signatures on macOS
• Certificate trust can be validated directly within the app
