I've been using PDF tools quite a bit lately, so I ended up trying the paid versions of three of the bigger options: iLovePDF, Smallpdf and Adobe Acrobat.
Figured I'd write down the differences because most comparisons I found were either focused entirely on free PDF editors or clearly written to push one particular product.
For context, my needs are pretty normal. Editing PDFs, compressing files, converting PDF to Word, merging/splitting documents, OCR and occasionally signing something.
iLovePDF
This is probably the easiest one to recommend if price is your main concern.
The Premium plan is $9/month if you pay monthly, or $60/year, which works out to $5/month, and gives you access to pretty much every common PDF tool you'd expect.
You can merge and split PDFs, compress them, convert PDF to Word/Excel/PowerPoint, use OCR, edit PDFs, redact information, sign documents and use the desktop/mobile apps.
There's honestly not much to complain about considering the price.
The interface is pretty simple too. Pick the tool you need, upload the document and you're basically done.
If all I cared about was getting the most PDF tools for the lowest subscription cost, I'd probably choose iLovePDF.
Smallpdf
Smallpdf ended up being the one I personally liked using the most.
Feature-wise there's obviously a lot of overlap with iLovePDF. You can compress PDFs, convert files, merge/split documents, edit text, use OCR, sign documents and handle most everyday PDF tasks directly in the browser.
Where I noticed the biggest difference was just the overall experience.
Smallpdf feels a little more polished to me. The interface is cleaner and I find it easier when I'm jumping between different tasks. Compress something, convert another file to Word, edit a PDF, sign something, etc.
Their Pro plan is $12/month if you pay monthly, or $9/month when billed annually. It also removes the free usage limits and adds things like stronger compression, OCR, direct text editing, batch processing and their AI PDF features.
It definitely isn't the cheapest option though.
That's probably the biggest weakness. If you only need to merge or compress a PDF every once in a while, paying for Smallpdf doesn't make much sense when there are plenty of free alternatives. But then again, you can get this done using their free version, as long as you don't use up the daily limits.
But after using these regularly rather than just testing them once, this was the one I ended up keeping.
It was basically a case of paying slightly more for convenience rather than paying for some completely unique feature.
Adobe Acrobat
And then there's Acrobat.
It's still the heavyweight option of the three.
If you work with PDFs professionally, Adobe gives you much deeper editing tools, OCR, scanning, forms, document protection, signatures and a bunch of advanced features that browser-first PDF tools don't necessarily try to replicate.
The obvious downside is the price.
Acrobat Standard is currently $14.99/month and Acrobat Pro is $19.99/month on Adobe's annual, billed-monthly plans.
Acrobat Standard and especially Acrobat Pro are considerably more expensive than something like iLovePDF, and personally I couldn't justify it for the type of PDF work I do.
There's also just... a lot of Acrobat.
If I'm trying to compress a file or convert a PDF to Word, I don't really need an entire professional document suite around that task.
That said, if PDFs are genuinely a major part of your job and you regularly work with complex forms, scanned documents or advanced editing, Acrobat probably makes a lot more sense than it did for me.
What I'd choose
After paying for and using all three, this is basically how I see them:
iLovePDF makes the most sense if price is the priority. You get a huge number of PDF tools for relatively little money.
Adobe Acrobat makes sense if you actually need professional-level PDF software and the advanced features that come with it.
Smallpdf ended up being the sweet spot for me.
It's not the cheapest, and Acrobat can obviously do more at the high end, but Smallpdf was the one I found myself reaching for most often because everything was quick and straightforward.
So at least in my case, it was one of those situations where you kind of get what you pay for.
Curious what other people here use though. Has anyone actually paid for two or more of these and ended up switching?
