5 Best Smallpdf Alternatives in 2026 (Free & Paid)

Smallpdf is one of the most well-known online PDF tools, but it's not without drawbacks. The free tier is limited, the Pro plan costs $12/month, and all your files get uploaded to their servers for processing. If any of those are dealbreakers for you, here are 5 alternatives worth considering in 2026.

What to Look for in a Smallpdf Alternative

Before diving into the list, here's what matters most:

• Core tools: Merge, compress, split, and convert should be available at minimum.
• Privacy: Does the tool upload your files to a server, or process them locally?
• Free tier: How much can you do without paying?
• Pricing: If you need a paid plan, is it reasonable?
• AI features: Can you chat with or summarize your PDFs?

1. AskPDF — Best for Privacy & AI

AskPDF processes PDFs entirely in your browser. Your files never touch a server. That's the single biggest differentiator — no other tool on this list can make that claim for all core operations.

Beyond privacy, AskPDF includes AI-powered features that Smallpdf doesn't have: chat with your PDF (ask questions and get answers from the document) and AI summarization (get structured summaries with key takeaways). These are powered by Claude, one of the most capable AI models available.

• Free tier: 5 operations/day, 10MB file limit, 3 AI questions/day
• Pro: $5/month — unlimited everything, 50MB file limit
• Privacy: Browser-based processing, no file uploads
• AI features: Chat with PDF, AI summarization
• Missing: PDF editing, e-signatures, PDF to Word

2. iLovePDF — Best for Feature Breadth

iLovePDF has been around for years and offers the widest set of PDF tools. Beyond the basics, it includes page numbering, watermarking, rotation, PDF editing, and more. If you need a Swiss Army knife for PDFs and don't mind server-side processing, iLovePDF delivers.

• Free tier: Limited daily operations, ads
• Premium: $7/month
• Privacy: Files uploaded to their servers
• AI features: None
• Strengths: Largest feature set, desktop apps, PDF editing

3. PDF24 — Best Completely Free Option

PDF24 is a German-made tool that offers most features for free without significant limitations. It has a web version and a desktop app for Windows. The interface is more utilitarian than polished, but it gets the job done.

• Free tier: Generous — most tools free with no daily limit
• Pro: Not needed for most users
• Privacy: Files processed on their servers (German hosting, GDPR compliant)
• AI features: None
• Strengths: Truly free, OCR, fax support, Windows desktop app

4. Sejda — Best for Power Users

Sejda is less well-known but packs serious functionality. It offers a full PDF editor, form filling, and even a desktop app. The free tier allows 3 tasks per hour with files up to 50MB — more generous on file size than most competitors.

• Free tier: 3 tasks/hour, 50MB file limit, 200-page limit
• Pro: $7.50/month
• Privacy: Files deleted after 2 hours; server processing
• AI features: None
• Strengths: Full PDF editor, generous free limits, desktop app

5. Adobe Acrobat Online — Best for Enterprise

Adobe literally invented the PDF format, so their tools are comprehensive and reliable. The online version offers basic merge, compress, and convert tools for free. However, anything beyond basics requires Acrobat Pro at $19.99/month — making it the most expensive option on this list by far.

• Free tier: Very limited (basic tools only, Adobe account required)
• Pro: $19.99/month
• Privacy: Files processed on Adobe servers
• AI features: AI Assistant in Acrobat Pro only
• Strengths: Industry standard, full editing, e-signatures, enterprise features

The Verdict

There's no single "best" tool — it depends on what you value:

• Privacy + AI: AskPDF. Browser-based processing and AI chat/summarization make it unique.
• Feature breadth: iLovePDF or Sejda. They have the widest tool sets.
• Completely free: PDF24. No meaningful limits for casual use.
• Enterprise/advanced editing: Adobe Acrobat. The industry standard, if you can afford it.

If you're reading this, you're probably looking for something that handles the core PDF tasks well, respects your privacy, and doesn't cost a fortune. That's exactly what AskPDF was built for.
