Why use A → B → C?

A pipeline feeds each result directly into the next compatible converter. Use one when the destination needs an intermediate representation or when you want to inspect and normalize that middle format.

JSON → CSV → XLSX turns records into rows before building a workbook.
Markdown → HTML → DOCX resolves markup before creating a document.
SVG → PNG → PDF intentionally flattens vector artwork before placing it on a page.

Only type-compatible next steps are offered. Lossy steps are marked before you run them.

About this conversion

How to convert RAR to TAR.XZ

Before you start

Paste RAR content or drop a matching file.

Accepted: .rar · application/vnd.rar, application/x-rar-compressed

Choose or drag one or more RAR files onto the drop zone.
Confirm the detected format and adjust the available settings. Mixed-format batches are flagged before conversion.

How this converter behaves

Compression and extraction happen against an in-memory file tree with path and expansion limits.

What happens to your data?

The conversion engine runs in this browser tab. OmniCastConverter has no upload API and never sends your content, file name, or converted result to a server.

Fidelity and limitations

This route is classified as lossless. The converter preserves meaning and structure supported by both formats.

No route-specific limitations beyond browser memory and the capabilities shared by both formats.
