How to convert an archive
- Select or drop one or more archives. ZIP, RAR, 7Z, TAR and TAR.GZ can all be read.
- Choose the target format: ZIP, TAR.GZ or TAR.
- Press Convert. Each archive is unpacked and repacked in your browser, then downloaded.
Private by design
This is the most self-contained tool on the site. The archive library is served from YUQUE itself rather than an external CDN, and unpacking and repacking both happen inside your browser tab. Your archives are not uploaded and their contents are never sent anywhere.
What this tool supports
- Reads ZIP, RAR, 7Z, TAR and TAR.GZ. The format is detected from the file's contents, so a mislabelled extension is handled correctly.
- Writes ZIP, TAR.GZ or TAR. RAR and 7Z can be opened but not created — those formats are read-only here.
- Folder structure preserved. One exception: empty directories are dropped, and the tool tells you when that happens.
- Encrypted archives not supported. A password-protected archive is rejected with a clear message rather than failing silently.
- TAR file names TAR stores names in 100 bytes. A longer path is reported instead of being silently truncated; choose ZIP for such archives.
- Browser support writing TAR.GZ needs the browser's built-in compression support. Where it is missing you are asked to pick ZIP or TAR instead.
- Size there is no fixed size limit. The whole archive is unpacked and repacked in memory, so a very large one uses more memory and takes longer; archives around 1 GB or more show a notice first and you can still choose to run the conversion.
Frequently asked questions
Are my archive files uploaded?
No. Archives are unpacked and repacked in your browser and are not sent to YUQUE or anywhere else.
Which archive formats can I convert?
You can open ZIP, RAR, 7Z, TAR and TAR.GZ, and save the result as ZIP, TAR.GZ or TAR. It is not an any-to-any converter: RAR and 7Z can be read but not written, so a RAR file can become a ZIP, but a ZIP cannot become a RAR.
Can I convert password-protected archives?
No. Encrypted archives are detected and rejected — there is nowhere to enter a password. Extract the archive with its password in another application first.
How large an archive can I convert?
There is no fixed limit. The whole archive is unpacked into memory and repacked there, so a larger one takes longer and uses more memory, and whether it finishes depends on how much memory the device has free — a tab has less to work with than a desktop program. Archives around 1 GB or more show a notice before the conversion starts, and you can still go ahead. If a conversion does run out of memory, you are told so instead of being left with a broken file.
