The problem
A recipient may need a PDF, an image or another audio format. Conversion should create a usable file, not merely change its extension.
A practical answer
GJ File Manager groups conversion tasks into images, audio, documents and ebooks, with compatibility information and progress.
Step by step
- Open the conversion center from the sidebar and choose the source category.
- Add a sample file, choose an output format and read compatibility notices.
- Keep the original and choose a separate output directory before starting.
- Open the result and inspect text, layout, imagery or sound for the intended use.

Know the limits
Complex Office layouts are not guaranteed to reconstruct exactly. Editable PDF conversion needs review; DRM-protected ebooks are unsupported.
Common question
Is renaming an extension enough?
No. Real conversion generates the target format's contents and should be checked in a suitable reader.
