The table tells a clear story: iLovePDF has breadth, JustPDF has privacy and simplicity. The rest of this page unpacks what those differences mean in practice.
Where iLovePDF wins
Credit where it's due. iLovePDF has been around since 2010 and has built one of the most comprehensive PDF toolkits available online. Here's where it genuinely holds an advantage:
- More tools (25+).iLovePDF covers niche operations like PDF to PDF/A conversion, page numbering, watermarking, and HTML to PDF that JustPDF doesn't currently offer. If you need a very specific PDF operation, iLovePDF is more likely to have it.
- Desktop application. iLovePDF offers a native desktop app for Windows and Mac. If you prefer working outside the browser or need offline access without loading a webpage first, this matters.
- Larger file support. Because iLovePDF processes files on their servers, they can handle very large files that might push a browser-based tool to its limits. The free tier allows up to 100MB per file.
- More mature ecosystem. With over a decade of development, iLovePDF has a bigger community, more tutorials, and broader third-party integration support.
- Team and enterprise plans. iLovePDF offers business plans with centralized billing, user management, and priority support that suit larger organizations.
Where JustPDF wins
JustPDF takes a fundamentally different approach. Every file operation runs inside your browser using JavaScript and WebAssembly. Nothing gets uploaded. That architectural choice creates several practical advantages:
- True privacy.Your files never leave your device. Not for one second, not to any server. You can verify this yourself by opening your browser's Network tab during any operation. Zero upload requests.
- No ads, ever. JustPDF has no banner ads, no interstitial popups, and no sponsored recommendations between operations. The free tier is clean.
- No account required. You can merge PDFs, compress files, or sign documents without ever entering an email address. Three operations per day, no strings attached.
- Much cheaper API.JustPDF's API plan is $9/month. iLovePDF's developer API starts at $4,500 per year. For small teams and indie developers building PDF workflows, that's a significant difference.
- No file size popups.Because processing is local, there are no server-imposed file size warnings. Your limit is your browser's available memory, which for most users means files well over 100MB work fine.
- Faster processing.There's no upload step and no download wait. When you split a PDF or convert PDF to Word, the result appears immediately. No progress bar watching your file crawl to a server in Barcelona and back.
- Cleaner interface.No upsell banners. No "upgrade now" overlays mid-operation. Just the tool, your file, and the result.
The ad and upsell experience
This is worth calling out separately because it affects every free user on every visit. iLovePDF's free tier comes with friction that goes beyond a simple daily limit:
- Banner ads on every page.iLovePDF displays advertising throughout the interface, including on tool pages where you're actively working with documents.
- Interstitial upgrade prompts.After completing an operation, you'll frequently see full-screen or modal prompts encouraging you to upgrade to Premium before you can download your result.
- File size warnings. Free users get file size limit warnings that push you toward a paid plan, even when the file is well within the stated 100MB limit.
- Feature gating mid-workflow.Some options appear available in the interface but reveal a paywall when you try to use them. You discover this after you've already uploaded your file and configured the operation.
- Repeated account prompts. After a couple of free operations, iLovePDF pushes you to create an account. Without one, continued use becomes increasingly restricted.
JustPDF has none of this. The free tier gives you 3 operations per day. When you hit the limit, you see a clear message. There are no ads, no interstitials, no bait-and-switch feature gates. If you want unlimited usage, the Pro plan is $4/month with no annual commitment required.
The privacy question: where do your files go?
This is the most important difference between the two tools, and it deserves a clear explanation.
When you use iLovePDF, your file is uploaded to their servers in Barcelona, Spain. The server processes it and sends the result back. iLovePDF states that files are deleted after two hours. They use encryption during transfer and hold ISO 27001 certification. These are reasonable security measures.
But the upload itself is the issue. During those two hours, your document exists on infrastructure you don't control. For a flyer or a public brochure, that's harmless. For a tax return, a contract, or a medical record, it creates exposure you can avoid entirely.
When you use JustPDF, your file stays on your device. The compression, OCR scanning, Word to PDF conversion, and every other operation runs in your browser. No network request carrying your file data is ever made. You can read more about this approach in our post on whether online PDF tools are safe.
Who should choose which?
Both tools serve real needs. The right choice depends on what you prioritize.
Choose iLovePDF if:
- You need a desktop application for offline PDF work without a browser
- You rely on niche tools like PDF/A conversion, page numbering, or HTML to PDF that JustPDF doesn't offer yet

- You handle sensitive documents — contracts, financial records, HR files — and want zero server exposure
- You want faster results without waiting for uploads and downloads
- You value transparent, straightforward pricing with no annual lock-in

Frequently asked questions
Is iLovePDF safe for sensitive documents?
iLovePDF uses encryption and claims to delete files after two hours. They hold ISO 27001 certification, which is a legitimate security standard. However, your files are uploaded to their servers for processing, which means they exist outside your control for a period of time. For highly sensitive documents, a browser-based tool like JustPDF that processes files locally is inherently more private.
Can I use iLovePDF completely for free?
iLovePDF offers a limited free tier with 1-2 operations per day and file size restrictions. You'll encounter ads, upgrade prompts, and eventually be asked to create an account. JustPDF offers 3 free operations per day with no account, no ads, and no file size popups.
Which is cheaper: JustPDF Pro or iLovePDF Premium?
JustPDF Pro costs $4/month with no annual commitment required. iLovePDF Premium is $7/month on a monthly plan, or $4/month if you commit to annual billing. On a month-to-month basis, JustPDF is nearly half the price. Both offer unlimited operations on their paid tiers.
Does JustPDF have all the same tools as iLovePDF?
Not all of them. iLovePDF offers 25+ tools, including some niche operations like PDF/A conversion and HTML to PDF that JustPDF doesn't currently have. JustPDF covers 17 tools including all the core operations: merge, split, compress, convert, sign, and OCR. For most users, the overlap covers everything they need.
Why is JustPDF's API so much cheaper than iLovePDF's?
Different business models. iLovePDF's developer API is priced for enterprise clients at $4,500/year. JustPDF's API is designed to be accessible to indie developers and small teams at $9/month. Both provide programmatic access to PDF operations, but the pricing targets very different audiences.
The bottom line
iLovePDF has earned its popularity. It's a comprehensive tool with a massive feature set and a proven track record. If you need the widest possible selection of PDF tools and don't mind the server-upload model, it's a solid choice.
But if you care about where your files go, want an ad-free experience, or just don't want to create yet another account to do something as basic as merging two PDFs, JustPDF offers a cleaner alternative. Your files stay on your device, the interface stays out of your way, and the pricing is straightforward.
You don't have to pick one permanently. Use iLovePDF when you need a niche tool it offers. Use JustPDF for the everyday PDF tasks where privacy and speed matter more than feature count.
