Adobe Acrobat Pro costs $30 AUD per month. That’s $360 per year for the privilege of editing PDFs — a file format Adobe created and then built a business around gatekeeping.

If you edit PDFs daily as part of your profession, Acrobat Pro might be worth it. But if you’re like most people — occasionally needing to fill a form, merge some documents, add a signature, or edit a few words — there are free alternatives that handle the job without the subscription.

I tested a dozen free PDF tools to find which ones actually work well and which ones are frustrating time-wasters. Here’s what I found.

What Most People Actually Need

Before diving into tools, let’s be honest about what most of us actually do with PDFs:

• Fill out forms (tax forms, applications, school paperwork)
• Sign documents (contracts, agreements, consent forms)
• Merge or split PDFs (combining scanned pages, extracting specific pages)
• Add annotations (highlighting, commenting, marking up documents for review)
• Basic text editing (fixing a typo, updating a date)
• Convert to/from PDF (Word to PDF, PDF to Word)

You don’t need Acrobat Pro for any of these tasks. You really don’t.

The Best Free Options

For Everything: Smallpdf (Free Tier)

Smallpdf is a web-based PDF toolkit that covers most common tasks: merge, split, compress, convert, sign, and annotate. The free tier limits you to two tasks per day, which is enough for occasional use.

The interface is the cleanest of any PDF tool I tested. Drop your file, pick what you want to do, download the result. No accounts required for basic tasks. The compression tool is particularly good — I reduced a 45 MB document to 8 MB without visible quality loss.

Strengths: Beautiful interface, works on any device with a browser, good compression. Limitations: Two free tasks per day, files are processed on their servers (privacy consideration for sensitive documents).

For Editing Text: LibreOffice Draw

Here’s a tip that most people don’t know: LibreOffice Draw can open and edit PDF files directly. Not perfectly — complex layouts sometimes shift, and heavily formatted documents can look odd — but for simple PDFs with text and basic formatting, it works surprisingly well.

You can click on text and edit it directly, add new text boxes, insert images, and even rearrange pages. It’s entirely free, open-source, and runs offline on Windows, Mac, and Linux.

I used it to update a date and contact details on a business proposal last month. Took about two minutes. Would’ve cost me $30/month in Acrobat subscriptions for a two-minute task.

Strengths: Real text editing capabilities, completely free, works offline, no upload to external servers. Limitations: Complex PDF layouts may not render perfectly, learning curve for first-time users.

For Forms and Signing: PDF Expert (Mac) / Xodo (Windows/Android)

If you’re on a Mac, the built-in Preview app handles form filling and basic annotation well. But PDF Expert offers a more polished experience for free (the paid upgrade adds OCR and advanced editing, but the free version covers signing and forms).

For Windows users, Xodo is the equivalent. It’s fast, handles form filling well, and the annotation tools are responsive. The signature feature lets you draw, type, or upload an image of your signature.

Both of these are also available as mobile apps, which matters when you need to sign something on your phone and send it back immediately.

Strengths: Fast, good form filling, signatures work well. Limitations: Limited editing capabilities in free versions.

For Merging and Splitting: PDF Arranger (Linux/Windows) / Preview (Mac)

Mac users have it easy: Preview lets you drag and drop pages between PDFs, delete pages, and reorder them. It’s built into macOS and works perfectly.

For Windows and Linux, PDF Arranger is a lightweight, open-source tool that does one thing well: rearranging, merging, and splitting PDF pages. The interface is simple — you see thumbnail previews of every page and can drag them around, delete them, or import pages from other PDFs.

No account. No internet connection required. No limitations.

Strengths: Simple, fast, does exactly what it says. Limitations: No editing, annotation, or form-filling capabilities.

For Batch Processing: pdf-tools Command Line

This one’s for slightly more technical users, but if you regularly need to process many PDFs (combining monthly reports, extracting specific pages from large documents), command-line tools like pdftk and qpdf are incredibly efficient.

A single command can merge 50 PDFs into one document, extract pages 15-20 from a 200-page report, or rotate all pages in a folder of scanned documents. Once you learn the basic commands, it’s faster than any graphical tool.

pdftk documentation is straightforward, and most common operations are one-liners.

Strengths: Fast, scriptable, handles batch operations effortlessly. Limitations: Command line interface isn’t for everyone.

The Privacy Question

One thing worth considering: web-based PDF tools like Smallpdf, ILovePDF, and PDF2Go process your files on their servers. For a recipe you’re converting or a public form you’re filling out, that’s fine. For tax returns, medical records, legal contracts, or business-sensitive documents? Think twice.

The tools that work offline — LibreOffice Draw, PDF Arranger, Preview, and command-line tools — keep your files on your machine. For anything confidential, these are the better choice.

What About Microsoft 365?

If you’re already paying for Microsoft 365 (and many people are, for Word and Excel), you’ve got decent PDF capabilities built in. Word can open and edit PDFs — with the same caveats as LibreOffice about complex layouts — and you can save any document as PDF from any Office app.

Edge browser also has built-in PDF annotation, form filling, and digital signing. It’s not the most feature-rich option, but it’s already on your Windows machine and handles the basics well.

When You Actually Need Acrobat Pro

To be fair, there are scenarios where free tools won’t cut it:

• OCR (Optical Character Recognition) on scanned documents. Making scanned PDFs searchable and editable requires good OCR, and Adobe’s is still the best. Some free tools offer OCR, but quality varies.
• Advanced form creation. Building interactive PDF forms with calculated fields, validation, and conditional logic is still an Acrobat stronghold.
• Legal/compliance workflows where specific PDF/A standards are required. Free tools don’t always maintain compliance with archival standards.
• Redaction. Properly redacting sensitive information (not just putting a black box over it, but actually removing the underlying data) requires tools that understand PDF structure. Getting this wrong can expose the information you thought you’d hidden.

For these use cases, the Acrobat subscription is justifiable. For businesses looking to streamline document workflows more broadly, AI automation services can help identify where PDF processing fits into larger efficiency improvements. But for everyday editing needs, the free alternatives covered here will serve you well.

My Recommendation

For most people, here’s what I’d suggest:

1. Mac users: Start with Preview (already installed). Add PDF Expert if you need better form handling.
2. Windows users: Install Xodo for forms and signing. Use LibreOffice Draw for text editing. Use PDF Arranger for merging and splitting.
3. Everyone: Bookmark Smallpdf for quick tasks on non-sensitive documents.

Save that $360 per year for something more enjoyable. Adobe won’t miss you.
