Do I need to install any software?

No installation required. The converter runs entirely in your web browser. No plugins, extensions or desktop apps needed.

How do I know the conversion was successful?

Xonvert validates the output file and shows a success confirmation. You can preview the result before downloading. If any issue occurs, a clear error message is displayed.

Is batch conversion available?

Yes. Drag or select multiple AZW3 files and they'll all convert to CBT simultaneously. Download results individually or as a ZIP.

Is this AZW3 to CBT converter free?

Yes, completely free. No registration, no hidden fees. Free users can convert files with Xonvert's full engine.

Why is my converted CBT file larger than the original AZW3?

File size depends on compression settings and content complexity. Try the Medium quality preset for smaller output, or the file may simply contain data that resists CBT compression.

What browsers are supported?

Chrome, Firefox, Safari and Edge (all recent versions). Any browser supporting WebAssembly will work.

Is there a watermark on converted CBT files?

No. Free conversions produce clean output with no watermarks. Your CBT file is identical to what a paid desktop tool would produce.
