How to convert RAR to ZIP
- Choose a .rar or .7z file (up to 300 MB).
- Check the summary: number of files, unpacked size and format.
- Tap Convert to ZIP, then download the .zip file.
How it works
The archive is read with libarchive, an open-source library that has its own RAR, RAR5 and 7z readers, compiled to run in your browser. Each file is unpacked in memory and written into a standard ZIP. Files that are already compressed, such as JPG, MP4, PDF or DOCX, are stored as they are, because squeezing them again only takes time. Everything else is compressed with Deflate, the method every ZIP tool understands.
Example
A 270-byte 7z archive holding notes/readme.txt (20 bytes) and data/numbers.txt (10,000 bytes of repeated digits) becomes a 306-byte ZIP with the same two files in the same folders. The ZIP is slightly bigger because 7z packs text more tightly, but both files come out identical.
Good to know
- Up to 5,000 files and 1 GB unpacked. Bigger archives are refused before anything is unpacked, which also protects you from "zip bomb" files.
- File names are cleaned so nothing can be written outside the ZIP's own folders, and repeated names get a number, like
report (2).pdf. - Links inside the archive are skipped; empty folders are kept.
Only need one or two files? Open RAR files lists everything inside and lets you save single files. To unpack a ZIP, use the ZIP extractor.
