How to change an EPUB cover online without damaging your ebook

Replacing an EPUB cover sounds simple, but a bad tool can stretch the image, crop important text, or package the EPUB incorrectly. The safest workflow is to preserve the original book structure and only replace the cover image you intentionally choose.

Quick answer

Use a browser-based EPUB cover changer, upload your EPUB, choose a new JPG, PNG, or WebP cover, preview the result, and download the updated EPUB. If privacy matters, choose a tool that processes files locally in your browser.

Step-by-step workflow

  1. Step 1

    Choose your EPUB file.

  2. Step 2

    Upload the new cover image you want to use.

  3. Step 3

    Pick the platform-ready output size.

  4. Step 4

    Use fit or fill mode to control whether the full image stays visible or fills the cover edge to edge.

  5. Step 5

    Preview the result, then download the updated EPUB.

What to check before export

The original preview should show the real original cover without fake cropping. The new cover preview should make it clear whether the image is being fitted with background space or filled edge to edge with some cropping. A trustworthy tool should never silently stretch the image.

If the image is smaller than the selected output size, resizing can make the file larger, but it cannot create real detail that was not in the source image. In that case, use the best original image you have.
