As someone who regularly deals with e-books, I've explored various tools to convert EPUB files to other formats, but converting EPUB to EPUB seems unnecessary at first glance. However, there are valid reasons—like fixing corrupted files or optimizing metadata. Online tools like 'Online-Convert' and 'Zamzar' can handle this, though they often require uploading your file to their servers, which might raise privacy concerns for some users.
For those who prefer not to upload sensitive content, Calibre is a fantastic offline alternative. It’s a powerful e-book management tool that allows you to tweak EPUBs without compromising quality. You can edit metadata, fix formatting issues, or even split/merge chapters. While online tools are convenient, I always recommend Calibre for its reliability and advanced features, especially if you’re dealing with a large library of e-books.

Editing an EPUB after converting from PDF can be tricky, but it’s totally doable with the right tools. I usually start by opening the EPUB file in Calibre, which is a fantastic ebook management tool. From there, I use the built-in editor to fix formatting issues, adjust fonts, or tweak the layout. Sometimes, the conversion messes up paragraph breaks or images, so I manually correct those. If the file is really messy, I might extract the HTML and CSS files using Sigil, a dedicated EPUB editor, and clean up the code directly. It’s a bit technical, but it gives me full control over the final look of the book. For minor edits, like fixing typos or adding bookmarks, I sometimes use EPUBee or online tools, but they’re not as powerful as Calibre or Sigil.

As someone who's been juggling ebook formats for years, Calibre is my go-to tool for all things conversion. Yes, it can convert EPUB to EPUB, which might sound redundant, but it's actually super useful. Sometimes EPUBs have hidden formatting issues or bloated files, and converting them to the same format can clean them up. I've fixed countless broken metadata or weird font issues just by running an EPUB through Calibre's conversion engine.
Another perk is adjusting the EPUB's structure—like removing embedded fonts or optimizing images—without changing the format. Calibre's 'Polish' feature is also great for tweaking EPUBs without full conversion. It’s like giving your ebook a fresh coat of paint while keeping everything intact. If you’re dealing with a messy EPUB, this trick can save you hours of manual editing. Just pick EPUB as both input and output, and let Calibre work its magic.

I’ve been a Mac user for years and love organizing my ebook collection, so batch converting EPUB files is something I’ve figured out. The best tool I’ve found is 'Calibre,' which is free and super powerful. After installing it, you just open the app, add all your EPUB files to the library, select them, and click 'Convert Books.' Make sure to choose EPUB as both the input and output format in the dropdown menu.
Calibre also lets you tweak metadata, covers, and other details in bulk, which is a lifesaver for large collections. If you’re dealing with DRM-protected files, you’ll need to remove the DRM first using tools like 'DeDRM' (though that’s a whole other process). For simpler conversions, 'Epubor Ultimate' is another option, but it’s paid and not as versatile as Calibre. Either way, batch conversion on Mac is totally doable with the right tools!

As someone who has spent years organizing digital libraries, I find EPUB to EPUB conversion incredibly useful for refining metadata, fixing formatting issues, or optimizing file sizes without altering the core format. EPUB is the gold standard for reflowable text, making it ideal for e-readers. Converting to another format like PDF or MOBI might break dynamic features like adjustable fonts or dark mode.
Sometimes, I just want to clean up an EPUB file—remove DRM, correct typos in the metadata, or embed fonts properly—without losing compatibility. Tools like Calibre allow batch conversions while preserving hyperlinks and table of contents. It’s like tidying up a book’s digital shelf without needing to rebuild it from scratch.

Converting an EPUB to EPUB might seem redundant, but it can involve subtle metadata tweaks depending on the tool or software used. The most common changes occur in the OPF file, which stores metadata like title, author, publisher, and language. Some converters might update the 'modified' date or clean up redundant tags, while others could accidentally strip out custom metadata like series information or reading progress.
Font embedding and cover image formats might also shift if the converter optimizes file sizes. If DRM was present in the original, it could be removed during conversion unless explicitly preserved. Some tools even normalize the EPUB's internal structure, altering file paths or compression methods without changing the visible content. Always check the output with an EPUB editor like Sigil to verify metadata integrity.

As someone who frequently manages digital libraries, I can say that converting an EPUB to EPUB typically doesn't reduce file size unless you modify the content or compression settings. EPUB files are essentially ZIP archives containing HTML, CSS, images, and metadata. If you recompress the files within the EPUB using higher compression ratios or remove redundant data like unused fonts or high-resolution images, you might see a reduction. However, a straightforward conversion without tweaks won't change much.
Tools like Calibre or online converters sometimes offer optimization options, such as stripping metadata or downsizing images, which can help. But if the original EPUB is already efficiently packed, the difference might be negligible. It's more about what you're willing to sacrifice—like image quality or extras—than the conversion itself.

As someone who's been collecting ebooks for years, I've dealt with DRM more times than I can count. Converting an EPUB to EPUB itself doesn't inherently remove DRM because it's just repackaging the same content. The DRM protection is like a digital lock on the file, and simply changing the container doesn't pick that lock.
However, if you use conversion tools that specifically strip DRM (like some Calibre plugins), then yes, the protection can be removed during the process. It's important to note that bypassing DRM is often against copyright laws and the terms of service of most ebook platforms. I've seen many discussions in tech forums where people debate the ethics of this, especially for personal backups of purchased books.
