Quick Comparison Table

Detailed Reviews

1. CheersPDF — Best Overall

CheersPDF stands out as the only online EPUB to PDF converter that works entirely in your browser. No file upload, no account, no limits. The conversion takes 2-5 seconds for typical ebook files.

Pros: 100% free, zero upload, offline capable, fastest speed, completely private

Cons: Ebook formats only (no Word, Excel, or image conversion)

2. Calibre — Best Desktop App

Calibre is the gold standard for ebook management. Its conversion engine is powerful and customizable, supporting 20+ formats. It processes locally, so privacy is excellent. The downside is it requires downloading and installing software.

Pros: Powerful, customizable, huge format support, local processing

Cons: Requires installation, steep learning curve, complex interface

3. CloudConvert — Best for Developers

CloudConvert offers reliable EPUB to PDF conversion with advanced options. Its REST API and integration with Zapier/Make make it ideal for automated workflows. Free tier allows 25 conversions per day.

Pros: API access, advanced options, reliable quality, GDPR compliant

Cons: Requires file upload, credit-based pricing, slower than local tools

4. Convertio — Good All-Rounder

Convertio handles EPUB to PDF alongside hundreds of other format combinations. Quality is generally good, but the free tier has meaningful limitations.

Pros: Wide format support, decent quality, no account for basic use

Cons: File upload required, premium plans expensive, daily limits

5. Zamzar — Established Option

Zamzar has been converting files since 2006. It handles EPUB to PDF reliably but with a 50 MB free limit and slower processing due to server round-trips.

Pros: Long track record, simple interface, many formats

Cons: 50 MB limit, relatively slow, expensive premium ($18/mo)

6. online-convert.com — Feature-Rich

Online-convert offers EPUB to PDF with extra options like custom page sizes and margins. It’s more configurable than most online tools but requires file upload.

Pros: Custom options, good quality, no account needed for basic use

Cons: File upload required, ads on free tier, limited free conversions

7. PDFCandy — Limited Free Tier

PDFCandy offers EPUB to PDF among its 47 tools. Quality is acceptable, but the one-task-per-hour free limit makes it impractical for multiple files.

Pros: Clean interface, desktop app available

Cons: 1 task/hour free limit, requires file upload

8. iLovePDF — PDF Suite Only

iLovePDF focuses on PDF manipulation (merge, split, compress) and has limited ebook conversion support. Not the best choice specifically for EPUB to PDF.

Pros: Good for PDF editing tasks

Cons: Limited EPUB support, requires upload, limited free tier
