How to Redact a PDF Without Adobe Pro: Free & Secure Methods

You can redact a PDF without Adobe Acrobat Pro using a desktop PDF editor, a Mac-native tool, or an online service. However, make sure the tool permanently removes the underlying content rather than simply placing a black or white box over it.

This guide explains how to redact a PDF without Adobe Pro and compares four practical alternatives so you can choose the right method for your document.

3 Best Ways to Redact a PDF Without Adobe Pro

Don't want to pay $20/month for solving how to redact in Adobe Acrobat Pro? Here's exactly how to redact it — for free, online, securely, and without uploading your files to unknown servers.

The right choice depends less on the number of features and more on what you're protecting and how you need to work with the document afterward.

The easiest options are:

• UPDF: Best for a desktop PDF editor with built-in redaction and search-based redaction.
• Preview: Best for basic PDF work on a Mac.
• Online redaction tools: Convenient for non-sensitive documents, but review their privacy and security policies before uploading files.

If the PDF contains highly sensitive personal, legal, financial, or business information, don't choose a tool based on price alone. Make sure it can permanently remove the underlying content, not simply cover it visually.

1. UPDF: Best for Desktop PDF Redaction

UPDF is a practical alternative if you want a dedicated PDF editor rather than a browser-based tool.

Its current redaction workflow supports manually marking text or images and using Search & Redact to find information across a document. You can also adjust redaction properties before applying the changes.

Why Use UPDF?

• Redact text and images manually
• Search for repeated text and redact multiple occurrences
• Redact pages
• Customize redaction properties
• Work within a broader PDF editing application
• Available across desktop and mobile platforms, with feature availability varying by platform

UPDF's current pricing page also shows that its free/trial experience has restrictions, including conversion limits and watermarks, while paid plans provide broader access. Therefore, don't describe the free version as completely unlimited.

How to Redact a PDF with UPDF

Step 1: Open your PDF in UPDF and select Tools → Redact.

Step 2: Select the text or image you want to remove.

Step 3: For repeated information, choose Search & Redact and search for the relevant word or phrase.

Step 4: Review the marked results carefully.

Step 5: Adjust the redaction properties if needed.

Step 6: Apply the redactions and save the result as a new PDF.

UPDF's current guide documents both manual redaction and Search & Redact workflows.

UPDF is a good fit if you regularly edit, annotate, convert, OCR, and protect PDFs in addition to redacting sensitive information.

What Else UPDF Can Do

Beyond redaction, UPDF is a complete PDF toolkit:

• Edit text and images — modify content directly in your PDF
• Annotate — highlight, underline, add sticky notes, and more
• Convert — export to Word, Excel, PowerPoint, and image formats
• Organize — merge, split, reorder, and delete pages
• AI features — summarize, translate, and chat with your PDF
• Cross-platform — Windows, Mac, iOS, Android

2. Preview: Best Free Option for Mac Users

Mac users can use Apple's built-in Preview for many basic PDF tasks without installing another application.

Redacting PDF in Preview is convenient because it is already included with macOS. However, it should be treated as a basic option rather than a full replacement for a professional PDF security workflow.

This way, you can redact the PDF with Preview. However, there are a few limits with Preview you should know about:

In short, Preview is a handy way to redact information on PDF without Adobe Pro if you are using macOS and want to fulfill basic redaction needs.

Preview makes sense when:

• You use a Mac
• You have a small number of PDFs
• Your redaction needs are basic
• You don't need advanced search-based or batch workflows

Limitations

Compared with dedicated PDF editors, Preview provides a more limited workflow for advanced redaction, document processing, and security management.

If you're dealing with legal, financial, medical, or other highly sensitive documents, verify that your version of macOS and Preview provides the exact redaction behavior you need before relying on it.

3. Online PDF Redaction Tools: Best for Convenience

Online tools can be useful when you need to redact a PDF quickly without installing desktop software.

However, online redaction introduces a different consideration:

You may need to upload the document to a third-party service.

For a non-sensitive document, this may be acceptable. For confidential documents, review the provider's privacy, retention, processing, and deletion policies before uploading the file.

1. PDFescape

PDFescape provides browser-based PDF editing features, including whiteout and shape-based ways to cover content. Its current free-plan limitations listed by UPDF include a 10 MB file limit and fewer than 100 pages, and it does not provide the same search-based multi-page redaction workflow as dedicated redaction tools.

For that reason, treat PDFescape as a basic PDF editing option rather than automatically assuming that every whiteout or rectangle operation is equivalent to secure redaction.

Follow the below steps to learn how to redact a PDF without Adobe Pro using the PDFescape online tool:

1. Go to the PDFescape website and upload the PDF you want to redact.
2. Click the "Insert" icon from the left sidebar and choose "Whiteout".

3. Drag the cursor over the text to whiteout.

4. You can also redact by inserting the rectangle. Click the second tap from the left sidebar and choose "Rectangle".

5. Drag the cursor over the text/image where you want to add the rectangle. Afterward, you can change the color of the rectangle if you want.

Although PDFescape provides an easy way to redact PDFs, there are a few cons associated with it, as follows:

In short, PDFescape provides a basic level of PDF redaction support. So, it is recommended to use only when you need to redact a few text/images in a small PDF file.

2. Redactable

Redactable is another online option focused specifically on PDF redaction. The workflow supports manual, search-based, and pattern-based redaction.

Its main trade-off is that the document is handled through an online service, so privacy requirements should be considered before uploading confidential files.

It allows you to redact text in the PDF manually, search-based, pattern-based, or autonomous. Follow the below steps to learn how to redact a PDF without Adobe Pro using Redactable:

1. Go to the Redactable website, sign up, and upload the PDF to redact.

2. Choose what type of redaction you want to perform.

3. Drag the cursor to redact the text you want. You can redact manually or use its search or pattern-based options to redact text quickly.

4. Once you have completed the redaction, click the "Finalize Redaction" to apply the redaction permanently and then download the file.

This way, you can redact PDFs with Redactable. However, you will notice some redaction limits while using Redactable, as follows:

In short, Redactable is useful if you just want to do basic redaction on small to large PDF files.

Now that we have looked into the above three alternatives, we can see that all have some limits/cons. File size limit, lack of search-based redaction, incompatibility to customize redaction colors, and similar others are major cons of many of them.

However, UPDF has no such cons. It provides the most intuitive, feature-rich, and limitless redaction support to redact easily and effectively. Therefore, why think more? Download UPDF and install the best PDF redaction alternative of Adobe Pro.

How to Redact a PDF Safely

Regardless of which tool you choose, follow the same basic process.

Before Redacting

1. Make a copy of the original PDF.
2. Identify every piece of sensitive information.
3. Search for repeated names, numbers, or phrases.
4. Check whether sensitive information also appears in images.
5. Decide whether hidden information needs to be sanitized.

After Applying Redactions

1. Save the redacted document under a new filename.
2. Close and reopen the PDF.
3. Search for the information you removed.
4. Check the redacted pages manually.
5. Verify that hidden information does not need additional sanitization.

Adobe specifically recommends saving a separate copy and provides a sanitization workflow for hidden information.
