The archive a friend sent in a format your device refuses — opened and repacked as a universal ZIP, on your own device.
RAR, 7Z, TAR, TAR.GZ, ISO… · converted to ZIP on your device, nothing is uploaded
No size limit · files are processed on your device and never uploaded · how it works
Runs in your browser. Files are never uploaded — you can go offline after the page loads.
How to use the Archive Converter (RAR/7Z → ZIP)
Drop one archive — RAR, 7Z, TAR, TAR.GZ, ISO and more.
It opens on your device; every file inside is listed (password prompt if the archive is locked).
Download the whole thing as a ZIP, or grab single files directly.
Easy to use
Drop files, pick options, download. Whole folders at once, no signup, no daily limit.
Best quality
The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.
Private & secure
Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
ZIP is the format that just opens
RAR needs WinRAR, 7Z needs 7-Zip, TAR.GZ confuses everyone outside Linux — but every operating system opens ZIP
natively, including phones. Converting an archive once removes the "can you resend that as a zip?" round-trip
forever. The conversion is a real repack: the archive is fully extracted by libarchive (the same engine behind
many desktop tools, compiled to WebAssembly) and rebuilt as a standard ZIP.
Because everything happens in your browser, the archive — and its password, if it has one — never leaves your
device. Often you don't even want the whole ZIP: every file inside is listed with its own download button. For
plain ZIP files, Unzip Files opens them directly, and Create
ZIP makes new ones.
Frequently asked questions
Why convert to ZIP at all?
ZIP opens everywhere with nothing installed — Windows, macOS, iPhones and Android all handle it natively. RAR and 7Z need extra software; converting once means the recipient (or future you) never hits that wall.
Which formats can it open?
RAR (incl. RAR5), 7Z, TAR and its compressed forms (.tar.gz, .tgz, .tar.bz2, .tar.xz), plus GZ, ISO, CAB, LZH and ZIP itself — everything the libarchive library reads, running as WebAssembly in your browser.
Are password-protected archives supported?
Yes — if the archive is encrypted you are asked for the password, and decryption happens entirely on your device. A few encryption variants (7z with encrypted headers, some AES modes) are beyond this build; the tool says so rather than failing silently.
Is there a size limit?
No fixed limit — the ceiling is your device’s memory, since the archive is unpacked and repacked in the browser. Multi-hundred-megabyte archives are fine on a laptop.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
