Where ILovePDF wins

1. Bigger feature surface

ILovePDF offers 30+ PDF tools, including:

• PDF to Word / Excel / PowerPoint (premium)
• Word / Excel / PowerPoint to PDF (free)
• OCR (image-PDF → searchable PDF, premium)
• Compare PDFs (premium)
• Sign PDF (premium)
• Edit PDF (premium)

DuneTools currently offers ~10 most-used PDF operations: compress, merge, split, rotate, watermark, page numbers, protect, unlock, organise, repair, plus PDF-to-JPG and JPG-to-PDF. If your need is in the longer tail (PDF-to-Word for instance), ILovePDF has it; DuneTools doesn’t yet.

2. Mobile apps

ILovePDF has solid iOS and Android apps that integrate with the system Files app. DuneTools is web-only, works in mobile browsers but no native app. For frequent on-the-go PDF work, ILovePDF’s apps are better integrated.

3. Established brand and ecosystem

15 years of operation, integrations with cloud storage (Google Drive, Dropbox, OneDrive), enterprise plans, decent customer support. DuneTools is newer (2025) and more lightweight.

Where DuneTools wins

1. Privacy: PDFs never leave your device

This is the headline difference. ILovePDF, like all server-based PDF tools, requires you to upload your PDF. Their privacy policy is reasonable (files deleted after 2 hours), but:

• The file was on their infrastructure.
• You can’t audit deletion.
• Subpoena, breach, or insider access could expose contents.

For PDFs containing:

• Tax returns and financial records
• Medical reports (HIPAA / GDPR)
• Legal contracts (potential privilege issues)
• NDA-bound client work
• Identity documents (passports, IDs, scans)

…uploading is a real risk.

DuneTools runs PDF processing entirely in your browser via WebAssembly libraries (pdf-lib, pdfjs, pdf-lib-with-encrypt for AES-256 encryption). Verify in DevTools → Network: zero outgoing payload during processing.

2. No daily quota

ILovePDF free caps at 25 file operations per day per IP. After that, you need to sign up (still limited) or pay (~$9/month). DuneTools has no quota, process 5, 50, or 500 PDFs today; same tomorrow. Free.

3. Larger file sizes accepted

Both offer 100 MB max files on free tiers. DuneTools’ real limit is your device’s RAM, an 8 GB laptop comfortably handles 200-300 MB PDFs (e.g. multi-hundred-page scanned contracts). ILovePDF can’t be coaxed past their server-side cap without a paid plan.

4. AES-256 encryption that actually works

Both tools offer “Protect PDF”. DuneTools uses pdf-lib-with-encrypt with AES-256, the same standard banks use. Verifiable in any PDF reader (Adobe will say “AES 256-bit”). ILovePDF does the same. Both are equivalent here, but DuneTools’ encryption happens client-side, your password is never transmitted.

5. No sign-up, no email, no upsell

DuneTools: drop, process, leave. ILovePDF: free quota → “Sign up for more” → “Try premium for advanced features” → marketing emails. If you value zero-friction tools, DuneTools wins.

Feature-by-feature deep dive

Compress PDF

Both use similar approaches: re-compress embedded images, preserve text vector data, optionally drop fonts. Compression ratios are within 10% of each other for typical inputs.

DuneTools advantage: smart target-based presets like Compress PDF to 1MB, drop the file, click the target, the algorithm hits within 5%. ILovePDF offers “low / medium / high” generic presets that don’t always hit specific size requirements (e.g. government 1 MB upload limits).

Merge PDF

Both drag-and-drop, reorder, merge. Equivalent functionality. ILovePDF has slightly better UX for very large merges (50+ files) due to server-side processing not constraining browser memory.

Split PDF

Both support split-by-page-range and split-by-page-count. Equivalent functionality.

Protect PDF / Unlock PDF

Both use AES-256 (industry standard). DuneTools’ implementation is client-side via pdf-lib-with-encrypt, your password never travels. ILovePDF does it server-side. For passwords, client-side is meaningfully more secure: even if ILovePDF is fully honest, a man-in-the-middle attack on the upload exposes the password.

Watermark / Page Numbers

Both offer text/image watermarks and configurable page numbering. Equivalent.

PDF-to-JPG, JPG-to-PDF

Both support common image conversions. Equivalent.

What ILovePDF has that DuneTools doesn’t

• PDF to Word / Excel / PowerPoint (premium-only on ILovePDF)
• OCR (premium-only)
• Compare PDFs (premium)
• eSign PDFs (premium)
• Edit PDF text (premium)

If any of these are critical, ILovePDF (or its Pro tier) is the right tool. DuneTools may add some of these in 2026 but currently doesn’t have them.

When to use which

Pick ILovePDF when:

• You need PDF-to-Word, OCR, or other ILovePDF-exclusive features
• You want a polished mobile app for on-the-go editing
• You’re already paying for an ILovePDF Pro account
• You’re processing 50+ MB scanned archives where browser RAM is a concern

Pick DuneTools when:

• The PDF contains sensitive content (legal, medical, financial, NDA, IDs)
• You’re hitting the 25/day free quota wall
• You want exact size targets (compress to 1 MB)
• You don’t want to sign up or share an email
• You’d rather your password and PDF stay on your device

Pricing breakdown

ILovePDF:

• Free: 25 ops/day, 100 MB max file, watermark-free
• Premium: ~$9/month, unlimited ops, larger files, OCR, PDF-to-Word
• Business: ~$60/user/month, team management, API

DuneTools:

• Free: unlimited ops, ~100 MB+ files (RAM-limited), all features
• No paid tier
• No team / API / OCR yet

For an individual or small team doing common PDF operations (compress, merge, split, protect), DuneTools’ free covers what most ILovePDF Pro users buy the subscription for.

The bottom line

ILovePDF is a strong, broad PDF toolkit, especially valuable if you need PDF-to-Word, OCR, or a polished mobile app. The 15-year track record matters; the integrations matter.

DuneTools is a credible alternative for the most-used PDF operations with two meaningful advantages: privacy (nothing leaves your browser) and no quota walls (process unlimited PDFs free). For 70% of “I just need to compress / merge / protect this PDF” cases, it’s the simpler and more private choice.
