FAQ

Frequently Asked Questions

What formats are supported?
Upload .epub or .kepub.epub files (EPUB2, EPUB3, and Kepub formats) and .png, .jpg, .jpeg, or .webp cover images. The new image replaces the existing cover inside the EPUB package while preserving all other content.
Is there a file size limit?
EPUB files up to 100 MB and cover images up to 20 MB. All processing happens locally in your browser, so speed depends on your device.
Are my files uploaded anywhere?
No. EPUB Cover Changer processes everything client-side using JavaScript. Your EPUB and images never leave your device — complete privacy by design.
What image dimensions should I use?
Most e-readers display covers at 1600 x 2560 pixels (roughly 2:3.2 ratio). Use that resolution or higher for the sharpest results across all devices.
How to change EPUB cover on iPhone?
Open this page in Safari or Chrome on your iPhone. Tap the left slot to choose your EPUB file from the Files app, tap the right slot to pick your new cover image from Photos, then tap Change. The new EPUB downloads to your Files app — open it with Apple Books and the new cover appears immediately.
Can I change EPUB cover on Kindle?
Yes. Change the new EPUB cover on any device using this tool, then send the updated EPUB file to your Kindle via Send to Kindle, email, or USB cable. This works for Kindle Paperwhite, Oasis, Scribe, and the Kindle app.
How to change EPUB cover without Calibre?
EPUB Cover Changer is a browser-based alternative to Calibre for changing EPUB covers. No software installation needed — upload your EPUB and a new cover image, click change, and download. Works on phones, tablets, and computers.
