As an IT professional and technology enthusiast, I‘ve explored virtually every option for annotating and editing PDF documents over the years. In this comprehensive 3000+ word guide, I‘ll share my insights on the best PDF editing tools and techniques based on extensive hands-on experience.

Whether you need to sign a document, fill out a form, or revise text, I‘ve got you covered with the most effective solutions in 2023. Let‘s dive in!

Why Edit PDF Files?

Before we get into the how-to, it‘s important to understand why you might need to digitally write on or modify a PDF file. Here are some of the most common uses cases:

Adding Notes and Comments

Annotating documents with highlights, underlines, and text notes is one of the most universal PDF requirements. Being able to add contextual comments makes PDFs infinitely more useful for collaboration and reference.

Filling Out Forms

From tax documents to insurance paperwork, many essential forms are distributed as static PDFs. Without form filling capabilities, these documents would be painful to complete.

Editing Text

Fixing typos, updating information, or making revisions all require directly editing text within a PDF. For content-heavy documents, full text editing capabilities are essential.

Signing Documents

Legally validating digital agreements, approvals, and contracts often necessitates an e-signature added directly to a PDF document.

Redacting Confidential Information

When sharing sensitive documents, you‘ll likely need to permanently remove confidential text, numbers, or images by covering them with black boxes.

Between adding annotations, filling forms, signing documents, and editing text/layouts, the ability to write on PDFs is a necessity in the digital workplace. Next I‘ll explore the top techniques and tools to accomplish these critical tasks.

The Old Standards: Adobe Acrobat and Microsoft Word

Historically, the original gold standard tool for editing PDF documents was Adobe Acrobat. As the inventor of the PDF format in the early 1990‘s, Adobe offered the most fully-featured options for manipulating PDF files.

The capabilities include:

  • Adding, editing, and formatting text
  • Annotations like highlights, notes, drawings
  • Redaction tools to permanently remove text
  • Form field recognition and editing
  • Page insertion, deletion, rotation, reordering
  • OCR conversion of scanned documents
  • Digital signature creation and validation
  • Password protection and document rights

With these robust features, Adobe Acrobat provides unparalleled control over PDF content and formatting. It remains the most powerful PDF tool available.

However, there are some significant downsides to Acrobat:

  • Cost – As part of Adobe‘s Creative Cloud, a full Acrobat license runs $180-360 per year. The free Reader app only allows viewing PDFs.

  • Steep learning curve – Acrobat‘s dense interface has a high barrier to entry for casual users.

  • Overkill for simple edits – Not everyone needs industrial-strength PDF tools.

For these reasons, many users turned to converting PDFs to Word documents for basic editing needs. Using Microsoft Word‘s editing capabilities and then reconverting back to PDF format works reasonably well with a few limitations:

  • Formatting inconsistencies on PDF→Word→PDF conversions
  • Loss of non-text elements like images, charts, etc.
  • Requires purchasing Word (part of $100/year Office 365)
  • Tedious multi-step process

Between the cost and complexity barriers, a growing market emerged for more affordable and usable PDF editing alternatives. Let‘s look at some of the top options now available.

Modern Solutions for PDF Annotations

If you just need to add some quick highlights or text notes to documents, dedicating Acrobat or Word feels like overkill. Luckily there are now many lightweight tools perfect for simple PDF annotations.

Preview App on Mac

All modern Mac computers come pre-installed with the Preview app. For basic annotations, Preview may meet your needs with no additional software required.

It allows you to:

  • Add text boxes, lines, shapes, highlights
  • Redact sections by covering with black boxes
  • Insert text signatures
  • Reorder pages
  • Type over text

While more robust programs offer greater controls, Preview provides usable free annotation features for most Mac users.

Markup on iOS

Similarly, iPhones and iPads include integrated Markup tools for annotating PDFs in the Books or Files apps. With just a few taps, you can:

  • Add text boxes
  • Draw shapes/lines
  • Highlight passages
  • Insert signatures
  • Markup images

It’s dumbed down compared to full PDF editors, but handy for quick notes and fills on-the-go.


For non-Apple devices, PDFescape provides one of the best free cloud-based PDF markup tools available:


Key features:

  • Add text, arrows, lines, shapes
  • Highlight and underline
  • Insert images
  • Free with no signup required

PDFescape works on any device with a browser giving you basic annotation powers without needing to install any apps.


For more advanced document markup capabilities, PDFelement provides a robust set of annotation tools:

PDFelement Annotation Tools

It enables:

  • Text boxes, callouts, annotations
  • Drawing markup tools
  • Typewriter tool for easy form filling
  • Shape recognition for drawing perfect lines/boxes
  • Collaboration via shared markups

With its sophisticated toolset, PDFelement excels at centralizing document markups for teams.

Key Takeaways

  • For personal use, built-in Preview and Markup apps provide adequate basic annotation features for free.

  • For business use, PDFelement hits the sweet spot with enterprise markup powers at an affordable price.

  • For maximum markup capabilities, Adobe Acrobat remains the leader (if you can afford it).

Editing PDF Text, Images, and Layout

Annotating is just one piece of the PDF puzzle. Many use cases require editing the actual text, images, layouts, and forms within a PDF file. Let‘s explore the key players in advanced PDF editing capabilities.

Microsoft Word (Roundtrip Method)

As mentioned earlier, Microsoft Word can edit PDF text by first converting to Word‘s native .docx format.

The pros of roundtripping through Word for PDF editing include:

  • Utilizes Word‘s superior text formatting capabilities
  • Easy to insert, delete, rearrange text
  • Familiar Word editing interface

However, there are also multiple downsides:

  • Tedious multi-step export/import process
  • Risk of formatting loss between PDF→Word→PDF
  • Unable to edit PDF elements like images

Round-tripping through Word works in a pinch, but falls short for complex PDF projects with specific formatting needs.

Adobe Acrobat DC

At the top of the PDF editing food chain sits Adobe Acrobat DC. It remains unrivaled in features for modifying PDF text, images, links, forms, and layouts.

Key capabilities:

  • Edit fonts, styles, spacing, alignment inline
  • Insert/replace text and images
  • Split, merge, delete, rearrange pages
  • Convert scans into editable documents via OCR
  • Create and integrate fillable forms
  • Batch process multiple documents
  • Built-in redaction tools

Frankly, there‘s little you can‘t do in terms of PDF manipulation with a full Acrobat license. But again the subscription pricing and learning curve limits the accessibility for many users.


For a friendlier PDF editing option, Wondershare‘s PDFelement offers a compelling balance of power and ease-of-use:

  • Intuitive ribbon interface

  • For larger business needs, Nitro Pro offers Acrobat-level features for less.

  • For maximum editing horsepower, Adobe Acrobat remains the leader, albeit at a premium price.

Specialized PDF Needs

Beyond annotations and editing, there are a few specialized use cases worth calling out separately:

OCR – Converting Scanned Docs to Text

When dealing with scanned or image-based PDFs, you‘ll need optical character recognition (OCR) to extract text for editing:

OCR PDF Example

  • Adobe Acrobat – Best OCR accuracy with close to 100% text conversion success.

  • PDFelement – Excellent integrated OCR engine with reasonable accuracy.

  • ReadIris Pro – Specialized OCR software with precision formatting retention.

Redaction – Removing Confidential Text

For securely sharing documents while permanently removing sensitive information:

Redacted PDF

  • Adobe Acrobat – Robust redaction tools built-in.
  • PDFelement – Very capable integrated redaction capabilities.
  • Microsoft Word – Basic redaction by covering text with black boxes.

PDF Accessibility – Text Readability

To create PDFs accessible to users with disabilities:

  • Adobe Acrobat – Industrty standard for authoring accessible PDFs.
  • Microsoft Word – Limited built-in accessibility checker.
  • CommonLook PDF – Adds accessibility features like tags/reading order.

Hopefully these specialized recommendations provide guidance for handling advanced PDF use cases as well.
