Online-Convert takes the complexity out of file conversion by handling everything through your web browser. Upload your EPUB, MOBI, AZW, or FB2 files, choose your target format, and get converted files ready for any device or platform. It's particularly useful for self-publishers who need to distribute across multiple platforms that each demand different file types.

How Online-Convert Works

Within minutes, you get a download link for your converted ebook, ready to upload to your chosen platform or load onto any compatible device.

  • Publishers working on different computers or devices regularly
  • Anyone dealing with foreign or legacy ebook formats

Online-Convert Pricing

Online-Convert offers a free plan that handles basic conversions with some file size restrictions. When you need to process larger files or want faster conversion speeds, paid plans start at $6. The upgrade removes size limits and gives you priority processing, which makes sense if you're converting full-length novels or image-heavy books. For occasional use, the free tier works fine, but regular publishers will likely find the paid version worth the investment.

Reviews of Online-Convert by Other Users

Users consistently praise the tool's reliability and ease of use, particularly compared to more complex desktop alternatives. Many self-publishers appreciate that it just works without requiring technical knowledge. The batch conversion feature gets frequent mentions as a time-saver. Common complaints center around file size limits on the free plan and occasional formatting issues with complex layouts. Some users wish for more detailed conversion settings, though most find the current options sufficient for standard publishing needs.

Online-Convert FAQ

Q: Will converting my ebook affect the formatting or image quality?

Most conversions preserve your formatting well, though complex layouts or custom fonts might need minor adjustments. Images typically maintain good quality unless you choose aggressive compression settings.

Q: How large can my files be on the free plan?

The free plan has file size restrictions that can block larger manuscripts, especially those with many images. The paid plan removes these limits entirely.

Q: Can I convert DRM-protected ebooks I purchased?

No, the tool cannot and will not convert copy-protected files. It only works with DRM-free ebooks that you own or have permission to convert.

Q: How long does conversion typically take?

Most standard ebook files convert within 2-5 minutes, though larger files or complex formats may take longer. Paid users get priority processing for faster results.

Q: Is my manuscript safe during the conversion process?

The service uses secure connections and automatically deletes files from their servers after conversion. Still, many authors prefer converting finished works rather than early drafts for extra peace of mind.

Summary

Online-Convert delivers exactly what most self-publishers need: reliable, straightforward ebook conversion without the learning curve. If you're distributing across multiple platforms or dealing with format compatibility issues, it solves the problem efficiently. The free plan works for occasional use, while the paid upgrade makes sense for regular publishers. Authors comfortable with technical tools might want more control, but for everyone else, this removes a genuine headache from the publishing process.
