Notes on Licensing Restrictions for Proprietary RAR Format
The RAR compression algorithm is a proprietary format. Its open-source tools only provide decoding licensing, and do not offer encoding licensing. Therefore, it only supports one-way conversion from RAR to ZIP, and cannot generate RAR format in reverse.
For compression tools to implement RAR encoding, they need to obtain commercial licensing from the original developer. Most free tools and online tools have not obtained this license, so they do not provide encoding output for RAR format.
Workflow of Online RAR Extraction and Conversion to ZIP
Users upload local RAR files to the online RAR extraction and conversion to ZIP tool, and the tool completes decoding and extraction of the RAR file on a cloud server to extract the original file content.
The tool re-encodes and packages the extracted original files into ZIP format, then provides the new ZIP file for users to download. The entire process does not require local installation of decompression software.
Native ZIP Format Support Across All Platforms
ZIP is an open format, and all mainstream operating systems have built-in native decompression support for ZIP format. After users download the converted ZIP file, they can directly open and view its content in the system without installing third-party software.
This solution is compatible with devices that cannot install third-party software, such as mobile phones, Mac computers, and office computers without administrator permissions, to meet the demand for temporarily opening RAR files.
| Operating System | Native System Decompression Support |
|---|---|
| Windows XP and later versions | Built-in ZIP decompression support |
| All official versions of macOS | Built-in ZIP decompression support |
| iOS 11 and later versions | Built-in ZIP decompression support |
| Android 8.0 and later versions | Built-in ZIP decompression support |
Processing Boundaries and Security Rules for Special RAR Files
Encrypted RAR files require users to enter the correct decompression password to complete decoding conversion. The tool does not store user-entered passwords, and cannot crack encrypted files with unknown passwords. Split RAR files require users to upload all volumes in order to complete full decompression and conversion.
The online RAR extraction and conversion to ZIP tool sets a 256MB decompression security limit. This restriction is used to prevent malicious compressed files such as zip bombs, and avoid damage to user devices and servers. Files exceeding this size are recommended to be processed with local decompression software.
الأسئلة الشائعة
Can encrypted RAR files be cracked online if the password is forgotten?
Cracking is not supported. Online tools only provide normal decompression and conversion services. Brute-force password cracking is an illegal act, and the tool does not provide this function. Any tool that claims to be able to crack passwords carries risks.
Why can't I extract while retaining the original RAR format online?
Most mobile devices and computers without dedicated software do not support native opening of RAR. Retaining the original format cannot solve the problem of opening without installation. Converting to ZIP is a solution that complies with licensing rules and allows native opening.
Will file content be leaked during online RAR conversion?
Regular tools will regularly clean up user files stored on the server after conversion is completed. Most tools do not retain user file content. For specific privacy rules, please refer to the public notice on the tool's official website.
