RAR to ZIP, in bulk.
RarZap extracts RAR archives and repacks them as ZIP — cleanly and fast. A native Rust app that streams each archive straight into its ZIP output, so even large files stay light on memory. The core is free and open source (MIT); the Commercial edition adds a real batch engine for converting whole queues.
Two editions, one tool
The converter itself is free and open source. If you convert archives in bulk, the Commercial edition unlocks the batch engine. No subscription either way — the Commercial edition is a one-time purchase.

Built for the pile, not the one
The Commercial edition's batch engine runs many conversions at once without freezing the UI — and keeps a single bad archive from ruining the run.
Parallel jobs
A task queue with a worker pool sized to your CPU, so several archives convert at once — smoothly.
Double progress
An overall progress bar plus a per-file progress column, so you always know where the queue stands.
Cancel anytime
Cancel-all stops cleanly at the next checkpoint and removes half-written output — no corrupt ZIPs left behind.
Failure isolation
One broken archive doesn't stop the batch. You get a summary with a one-click "retry failed items".
Thousands of rows
A virtual-scrolling list stays at full frame rate even with a thousand files queued.
Tune the load
Set the parallelism yourself — conservative for HDDs, higher for SSDs — so throughput stays healthy.
How it works
RAR is a read-only, proprietary format — nothing but RAR's own tools can create one. So RarZap does the honest thing: it extracts the archive and repacks the contents into a standard ZIP.
Open the RAR
Reads the archive with a fast batch-capable extractor.
Repack as ZIP
Streams each entry straight into a Deflate ZIP — no giant temp copies.
Write the output
Produces a portable .zip next to the source, ready anywhere.
Fast and memory-light
The extractor is tuned for batch workloads, and archives are processed as a stream rather than loaded into memory — so a 2 GB RAR doesn't need 2 GB of RAM. Output uses Deflate by default for maximum compatibility.
Built native
RarZap is a native GPU-rendered desktop app — no Electron, no browser engine. It starts fast, scrolls huge lists without stutter, and has no web view to sandbox.
Everywhere you work
Native builds for the three desktop platforms, in eight languages (English by default — it follows your system language and falls back to English).
🪟 Windows
Inno Setup installer. A Microsoft Store listing for the Commercial edition is coming.
🍎 macOS
Signed and notarized .dmg, so it opens without security warnings.
🐧 Linux
A .deb package for Ubuntu / Debian and friends.
Questions, answered
What's the difference between the free and Commercial editions?
The free, open-source edition converts RAR to ZIP one archive at a time. The Commercial edition adds the batch engine — queues, parallel jobs, per-file progress, cancel-all and failure isolation — plus an activation code and priority updates. Everything else is identical.
Why convert RAR to ZIP at all?
ZIP opens natively on every system — Windows Explorer, macOS, Linux — with no extra software. RAR requires a dedicated extractor, and RAR's format can't be created by third-party tools. Converting to ZIP makes the contents universally readable.
Is there a free trial of the Commercial edition?
No. RarZap doesn't use a trial: the converter is free and open source, and the Commercial edition is a one-time $9 purchase that unlocks the batch engine. There's nothing to cancel.
How do I get it?
The free edition is on GitHub Releases. The Commercial edition can be bought here (card / Apple Pay / Google Pay via Creem) and, once listed, on the Microsoft Store. Your activation code is emailed and stored in your account.
Will it lose or alter my files?
No. RarZap extracts the original entries and writes them into a new ZIP — the file contents are copied as-is.
Your source RAR is left untouched; the .zip is written alongside it.
Does it need an internet connection?
Only to activate the Commercial license. Converting is fully offline.
