AZW3 to MOBI questions

Short answers about limits, privacy, and keeping the converted file.

Why won't my AZW3 convert?

If the book came from a store, it probably has DRM, which blocks conversion. DRM-free ebooks convert normally.

Is the AZW3 to MOBI converter free?

Yes. Without an account you can convert up to 10 files a day, 2 at a time, up to 25 MB each. A free account adds monthly conversion credits and larger files.

How long are my files kept?

Guest uploads and results are deleted automatically after 1 hour. Conversions stay temporary when you are signed in too, unless you save a result to your workspace.

Can I get a permanent link to the MOBI file?

Yes. Save the result to a SteadyLink workspace and it gets a stable link. If you make a new version later, replace the file and the link stays the same.
