Is my EPUB file uploaded to a server?

No. Everything runs in your browser using the JSZip library. Your file never leaves your device.

What if the EPUB has no cover image?

The tool will show a "No cover image found" message. Some EPUBs, particularly older or plain-text ones, do not include embedded cover art.

What image formats can be extracted?

EPUBs typically embed covers as JPEG, PNG, GIF, or WebP. The tool previews the embedded image and converts it to a real JPEG file before download.

The cover shown looks low-resolution — why?

The resolution is determined by the image embedded inside the EPUB itself. Some publishers include only a thumbnail-sized cover; others include a full-resolution image. This tool displays whatever is stored in the file.

Can I extract images from individual pages?

This tool focuses on the declared cover image. Extracting images from arbitrary pages of an EPUB requires a full rendering engine and is beyond the scope of this tool.

What EPUB versions are supported?

Both EPUB 2 and EPUB 3 are supported. The tool reads the OPF manifest and metadata to locate the cover regardless of version.
