Calculation Logic
This tool operates purely on the client-side: it reads archives as binary ArrayBuffers and uses native File APIs. For ZIP processing, it utilizes JSZip for deflate algorithms; for TAR processing, it executes clean Javascript header calculation and null-padding.
All conversion and repacking runs inside the browser sandbox, which ensures zero remote network exposure.
FAQ
Is it safe to convert archives containing proprietary code or private keys here?
Yes, absolutely. Unlike standard cloud-based converters, this tool runs 100% locally in your browser. Your files are never sent to any server.
Do you support encrypted or password-protected archives?
No. Due to browser sandbox constraints, we do not support converting password-locked ZIP, RAR, or 7Z archives.
What is the maximum file size limit for converting?
There are no artificial limits from our side. However, since files are loaded into browser RAM, converting archives larger than 200MB may cause tab crashes on mobile or low-spec devices.
Why is converting local files so much faster than other sites?
Why is converting local files so much faster than other sites? Because there is no network transfer delay. You don't have to upload your files to a server and download them back, making the conversion almost instantaneous.
