ezyzip.com
Opens and builds ZIP, RAR and 7z archives without uploading them.
Extracts and creates archives in the page itself — the site states plainly that files never leave your device — across a couple of hundred archive formats including split and password-protected ones. It is the answer on a locked-down work laptop where you cannot install 7-Zip but someone has sent you a .rar. Nothing is stored, so nothing can be recovered if you close the tab mid-job.
AltFTool does this too
If you would rather not leave the site, ZIP/TAR Archive Surgeon covers the same job here — free, no account, and it runs in your browser.

Works the moment the page loads. No account, no email, no trial. Ad-heavy, and because everything runs in the tab a multi-gigabyte archive is limited by your browser's memory.
No. ezyZip does the work inside your browser, so the file never leaves your device — you can load the page, disconnect from the network, and it still works. That makes it a reasonable choice for material containing personal data.
