How to Change an EPUB Cover Image

The cover is the first thing anyone sees when browsing an eBook library. If you have an EPUB with a wrong cover, a missing cover, or just an ugly one — this guide shows you how to fix it in seconds.

Why Would You Want to Change an EPUB Cover?

There are more reasons than you might expect:

The cover is wrong: Some EPUBs downloaded from the web have incorrect or placeholder covers.

The cover is missing: Older or poorly formatted EPUBs sometimes have no cover at all, showing a blank thumbnail in your library.

You made the EPUB yourself: Authors and self-publishers often need to swap in a final cover image after assembly.

You want a cleaner library: If you manage a large eBook collection, consistent, recognizable covers make browsing much easier.

You prefer a different edition's artwork: Different releases of the same book often have different cover designs.

What You'll Need

Your EPUB file

A replacement cover image (JPG or PNG works best) — or nothing, if you just want to remove the cover

That's it. No software to install, no account to create.

How to Change an EPUB Cover — Step by Step

Step 1: Open the Tool

Go to the Change EPUB Cover tool. It works in any browser on any device.

Step 2: Upload Your EPUB

Click the upload area or drag your EPUB file in. The file is processed on our servers and not stored.

Step 3: Upload a New Cover Image (Optional)

Upload the image you want to use as the new cover. JPG and PNG are ideal. If you leave this empty, the existing cover will be removed.

Step 4: Download the Modified EPUB

Click the button and your updated EPUB downloads automatically. Load it into your eBook reader or library app and the new cover will appear.

Removing a Cover Instead of Replacing It

If you just want to strip the cover out — without adding a new one — simply leave the image upload empty. The tool will blank out the cover page, keeping the rest of the book intact.

You can also add a short line of text (like the title or author name) to appear on the blank cover page instead of leaving it completely empty. Useful when you don't have a cover image handy but still want something to show in your library.

Tips for a Good Cover Image

Use JPG for Photos, PNG for Graphics

If your cover is a photograph or has a lot of color gradients, JPG is fine. If it has sharp text, flat colors, or transparent areas, PNG will look cleaner.

Keep the File Size Reasonable

A cover image over 1–2 MB is usually unnecessary and adds size to the EPUB. Most cover images are well under 500 KB.

Check the Result in Your Reader

Different eBook apps display covers differently. After replacing the cover, open the EPUB in your preferred reader (Apple Books, Kindle, etc.) to confirm it looks right.

Common Questions

Will changing the cover affect the rest of the book?

No. The tool only modifies the cover image and the metadata that points to it. The text, chapters, and formatting of the book are untouched.

What if my EPUB didn't have a cover to begin with?

If there's no existing cover in the EPUB, the tool will still work — it removes the old cover (if any) and adds the new one. The result is an EPUB with a clean, properly registered cover image.

Does this work on MOBI files?

The tool works with EPUB files. For MOBI, convert to EPUB first, then change the cover.
