Is there any Mac software to handle archives (zip, rar, 7z, tar, etc.) that allows browsing?

iUnarchive seems to be quite nice. It is available at the App Store.

iUnarchive can be used to preview and extract files from archives. Instead of cluttering the disk with files, you can preview and open files directly from within iUnarchive.

Only files selected for preview and extracted files are actually uncompressed.

Supported archives include zip, rar, 7-zip, tar, gzip, bz2/BZip2, LhA and StuffIt, including password protection for zip, 7-zip, rar and multi part rar.

Edit: Not sure if you looked for a free application. It costs 4 Euro now (I think it was free before).

Zipeg allows you to browse and uncompress a number of formats, but does not allow compressing.

Apple actually has an example application called ZipBrowser on their developer site. The direct download is located here. Unfortunately this only works with zip files. The actually app is only 600K so it's nice and small. (Note that ZipBrowser only works on 10.6+)

I know this thread is old, but to anyone looking for an answer; the best tool I have found is the B1 Free Archiver.

It works on all platforms (even Android), and is simple and easy to use. It's fast, free, and it supports most compression formats (including zip, 7-zip, rar, dmg, and more :)).

Springy can do this.

From Softonic:

Springy integrates with Finder to make archiving as simple as drag and drop or through Springy’s Finder contextual menu. One thing I really like is that you can preview and browse archives before extracting them - very useful if you're dealing with big archives. Extracting and compression is extremely quick and you can modify files within an archive just by double clicking. Most major formats are supported including: ZIP, TAR, RAR, 7Z, PAX, CPIO, CPGZ, GZIP, BZIP2, UNIX Compress, SIT, JAR, DMG and ISO disk images. Note that as an added bonus, you can also create disk images with it as well.
