What happens when you convert 7Z to ZIP
- Every file and folder in the 7Z is extracted in your browser and packed into a new ZIP with the same structure. Nothing is uploaded.
- ZIP opens on every computer and phone without extra software, which is usually the point of converting.
- Password-protected archives cannot be converted, because they cannot be opened without the password.
How to convert 7Z to ZIP online
- Press "Choose 7Z files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to ZIP". The archive engine, about 1 MB, loads the first time; then the time depends on how much is inside the archive.
- Save each ZIP with its download button. Close the tab and every trace of the files is gone from memory.
Why convert 7Z to ZIP?
7Z files usually come from maximum compression for backups and software distribution. People convert them to ZIP because ZIP opens on every computer and phone with no extra software.
In short, 7Z is good at what it was made for, and ZIP is the more practical choice when the file has to open, upload or print somewhere else. 7Z opens natively in Windows 11 since its 2023 update; older Windows needs 7-Zip and a Mac needs The Unarchiver, while ZIP opens with the built-in tools of Windows, macOS, iOS and Android.

Best settings for 7Z to ZIP
There is nothing to set: every file in the 7Z is copied into the ZIP as it is.
Large archives are unpacked into your browser's memory, so very big ones, several gigabytes, are better handled by a desktop program such as 7-Zip. Archives split into several parts (.part1.rar, .part2.rar) need all parts, which this tool does not join.

About 7Z and ZIP files
What is a 7Z file?
7Z usually compresses tighter than ZIP by using the LZMA algorithm across files. The trade-off is that fewer built-in tools can open it.
What is a ZIP file?
ZIP is the one archive format every operating system opens without extra software, which is why converting other archives to ZIP is so common.
7Z to ZIP not working? Common problems
- The archive will not open. It may be password protected, damaged, or one part of a multi-part archive.
- The browser tab stops on a big archive. Everything is unpacked in memory; very large archives are better handled by 7-Zip or The Unarchiver.
- Files have odd names. Archives made on some older systems store names in a local character set; the files themselves are intact.
Convert 7Z to ZIP from the command line
7-Zip extracts any of these formats, and a second command packs the result:
7z x input.7z -oextracted
cd extracted && 7z a ../output.zip .The converter on this page does the same job in your browser, without installing anything.
7Z to ZIP converter FAQ
Will I lose quality converting 7Z to ZIP?
No. Archives are lossless: every file comes out byte for byte identical.
Why is the ZIP a different size from the 7Z?
Different archive formats compress differently, so the ZIP may be larger or smaller than the 7Z.
Are my 7Z files uploaded anywhere?
No. The conversion runs inside this browser tab using libarchive compiled to WebAssembly and the fflate ZIP library, so your files stay on your device. You can disconnect from the internet after the page and converter engine have loaded and it still works.

Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a ZIP file?
ZIP opens with the built-in tools of Windows, macOS, iOS and Android. ZIP is common for sending several files at once and downloading software.

Can I convert 7Z to ZIP on my phone?
