Got an EPUB file that needs to be a PDF? Maybe you want to print an ebook, share a document that looks the same on every device, or just open it in a reader that doesn’t support EPUB. Whatever the reason, the conversion is straightforward once you know which tools actually work.
I tested 8 converters over the past two weeks – desktop apps, online tools, and a couple of browser extensions. Some nailed the formatting, others mangled it. Here’s what I found, starting with the tools that gave me the cleanest output.

1. Calibre – Best Overall (Free, Desktop)
Calibre has been the go-to ebook management tool since 2006. I’ve used it on and off for years. For EPUB-to-PDF conversion specifically, nothing free comes close in terms of output quality and control.
How to convert EPUB to PDF with Calibre
- Download Calibre from calibre-ebook.com (Windows, Mac, Linux)
- Click “Add books” and select your EPUB file
- Select the book, click “Convert books” in the toolbar
- Set output format to PDF (top-right dropdown)
- Adjust page size, margins, and fonts under “PDF Output” tab
- Hit OK and wait – usually takes 5-30 seconds
The PDF Output tab is where Calibre shines. You can set custom page sizes (A4, Letter, or pixel-exact dimensions), control margins, choose serif or sans-serif fonts, and even insert headers/footers with page numbers. I converted a 400-page novel and the output looked like a professionally typeset book.
Pros
- Completely free, no ads, open-source
- Batch convert hundreds of files at once
- Granular control over page layout, fonts, margins
- Works offline – no file uploads to third-party servers
- Handles EPUB, MOBI, AZW3, DOCX, and 20+ other formats
Cons
- Needs installation (about 130 MB)
- Interface feels cluttered if you just want a quick conversion
- Complex CSS in some EPUBs may render differently than expected
2. CloudConvert – Best Online Option
When I don’t want to open Calibre for a single file, CloudConvert is my fallback. The free tier gives you 25 conversions per day, which is generous compared to most online tools.
Upload your EPUB, select PDF as output, and download. The whole thing takes maybe 15 seconds for a typical ebook. CloudConvert processes files on their servers and deletes them after 24 hours (they claim – I can’t verify that, obviously).
Formatting was solid in my tests. A tech manual with code blocks, tables, and inline images came through cleanly. One thing I noticed: footnotes sometimes end up as endnotes in the PDF output. Not a dealbreaker, but worth knowing.
Pros
- 25 free conversions daily – more than most competitors
- 1 GB max file size on free tier
- Batch processing (up to 5 files simultaneously)
- API available if you need automation
Cons
- Requires uploading files to their server
- Occasional queue wait times during peak hours
- Paid plans start at $8/month if you exceed free limits
3. Zamzar – Simplest Interface
Zamzar has been around since 2006, and honestly the interface hasn’t changed much. That’s not a complaint – it’s three steps: upload, choose format, convert. No account needed for basic conversions.
The catch: the free tier only allows 2 conversions per day with a 50 MB file limit. For occasional use that’s fine. For anything more, you’re looking at $18/month for their Basic plan.
Output quality was acceptable. Text-heavy EPUBs converted well. An illustrated children’s book I tested lost some image positioning – images that were supposed to wrap text ended up on their own lines instead.
Pros
- Dead-simple interface, no learning curve
- No account required
- Email notification when conversion is done
Cons
- Only 2 free conversions per day
- 50 MB file size cap
- Less control over output formatting than Calibre
- Paid plan is expensive for what you get
4. Convertio – Good Middle Ground
Convertio sits between Zamzar’s simplicity and CloudConvert’s flexibility. You get 10 free conversions per day, 100 MB file limit, and the interface is clean without being oversimplified.
I tested it with five different EPUBs in one session. Four came out great. The fifth – a technical manual with SVG diagrams – had rendering issues where some diagrams appeared pixelated. If your EPUB contains mostly text, you won’t have problems.
One nice touch: Convertio lets you convert files directly from Google Drive or Dropbox. Saves the upload step if your EPUBs are already in cloud storage.
Pros
- 10 daily free conversions
- Google Drive and Dropbox integration
- Supports 300+ format combinations
- Clean, modern interface
Cons
- 100 MB file size limit on free tier
- SVG and complex vector graphics may not render perfectly
- Creates an account automatically if you provide email
5. Online-Convert – Best for Custom Page Settings
Online-Convert gives you more control than most web-based tools. Before converting, you can specify target ebook reader, change page size, set DPI, and even apply optional OCR if your EPUB contains scanned images.
The free tier is limited to 3 conversions per day. Not great. But if you need specific page dimensions or DPI settings without installing Calibre, this is the tool.
I used it to convert an EPUB to a print-ready A5 PDF. The output was clean, margins were correct, and the font sizes scaled properly for the smaller page format. None of the other online tools offered this level of customization.
Pros
- Custom page size, DPI, and margin settings
- Optional OCR for image-based content
- No account required
Cons
- Only 3 free conversions daily
- Interface is busier than competitors
- Ads on the free version
6. EPUB.to – No Signup Required
EPUB.to is a single-purpose site. You upload an EPUB, it gives you a PDF. No signup, no email, no daily limits that I could find (I converted 8 files in one afternoon without hitting any wall).
The tradeoff is zero customization. You can’t adjust page size, margins, or fonts. What you get is what you get. For most novels and simple non-fiction, the default settings produce a readable PDF. For anything with complex formatting, use Calibre instead.
Pros
- No signup or account needed
- No apparent daily conversion limit
- Fast processing
Cons
- No formatting options at all
- 50 MB file size cap
- Ad-heavy website
7. To PDF (toepub.com) – Minimal and Fast
Another straightforward converter. Upload, convert, download. I’m including it because it handles batch uploads better than EPUB.to – you can drag multiple files and it processes them in sequence.
Quality is average. Text formatting holds up, but images sometimes lose resolution. Headers and footers from the EPUB structure don’t always carry over into the PDF correctly.
Pros
- Drag-and-drop batch uploads
- No registration
- Processing is fast (under 10 seconds per file)
Cons
- Image quality can degrade
- Headers/footers may not translate
- Limited to 50 MB files
8. LibreOffice – If You Already Have It
LibreOffice can open EPUB files (with the writer2epub extension) and export to PDF via File > Export as PDF. Honestly, I wouldn’t install LibreOffice just for this. It’s a 300+ MB download. But if it’s already on your machine, it works.
The PDF export dialog in LibreOffice is actually powerful – you can set PDF/A compliance, embed fonts, control image compression, add watermarks, and set security permissions. For creating archival-quality PDFs from EPUBs, it’s overkill in the best way.
Pros
- Free, open-source
- Advanced PDF export options (PDF/A, encryption, compression)
- Works offline
Cons
- Requires extension installation for EPUB support
- Large download if you don’t already have it
- EPUB rendering can be inconsistent
Which Method Should You Use?
Here’s the thing – your choice depends on two factors: how many files you need to convert and whether you care about formatting control.
Converting one file right now? Use CloudConvert or EPUB.to. No install, takes 20 seconds.
Converting multiple files or need specific formatting? Install Calibre. The 5 minutes you spend downloading it will save you time compared to uploading files one by one to web tools.
Need print-ready output with exact dimensions? Calibre or LibreOffice. Online tools don’t give you enough control over page layout for printing.

Tips for Better EPUB to PDF Conversion
After running dozens of test conversions, a few things stood out:
Check the source EPUB quality first. Open it in an EPUB reader (like Apple Books or Thorium Reader) before converting. If it looks broken there, no converter will fix it. Garbage in, garbage out.
Embedded fonts matter. Some EPUBs use custom fonts that don’t embed properly in PDF. If your converted PDF shows wrong fonts, try Calibre with the “Embed font family” option set to a standard font like Georgia or Arial.
Page size makes a huge difference for readability. EPUB text is designed to reflow, so cramming it onto a small PDF page creates tiny text. For reading on screen, use Letter or A4 size. For e-reader devices, try 6×9 inches.
Images in EPUBs are often low-resolution. They look fine on a phone screen but appear blurry when printed from a PDF at 300 DPI. There’s no way around this – the original images need to be high-resolution.
DRM-protected EPUBs won’t convert. If you bought an ebook with DRM, standard tools will refuse to process it. You’d need to contact the publisher for a DRM-free version or purchase the PDF edition separately.
FAQ
Can I convert EPUB to PDF for free?
Yes. Calibre is 100% free, open-source, and handles unlimited conversions offline. Online tools like CloudConvert and Zamzar offer free tiers with daily limits (typically 2-25 files per day).
Does converting EPUB to PDF lose formatting?
Some formatting changes are inevitable because EPUB is reflowable (text adjusts to screen size) and PDF is fixed-layout. Calibre preserves formatting best when you set the correct output profile and page size. Complex layouts with embedded fonts may shift slightly.
What is the best free EPUB to PDF converter?
Calibre is the best overall option. It’s free, has no file limits, works offline on Windows, Mac, and Linux, and gives you full control over the output. For quick one-off conversions without installing software, CloudConvert works well from a browser.
Can I convert DRM-protected EPUB to PDF?
No. DRM-protected EPUB files cannot be converted by standard tools. Calibre and most online converters will refuse to process DRM-locked files. Contact the publisher or purchase a DRM-free version if you need a PDF.
Is Calibre safe to download?
Yes. Calibre is open-source software maintained since 2006 with millions of active users. Always download it from the official site (calibre-ebook.com) to avoid bundled adware from third-party download sites.
