How do I convert 7Z to ZIP?

Add your 7Z file to the upload area above, then press Convert. The ZIP file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to ZIP reduce quality?

File contents are byte-identical; only the container changes.

How large a file can I convert?

Up to 500 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

7Z and ZIP explained

7z uses LZMA compression and creates solid archives, treating the files as one continuous stream. That yields notably better ratios than ZIP, especially with many similar files.

ZIP bundles multiple files into one and compresses them. Its indispensable property is that every operating system can open it with no extra software.

Where 7Z files come from: Large downloads and backups where size matters.
Where ZIP is used: Email attachments, downloads and file transfers.

7Z vs ZIP

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

7Z compared with ZIP
Property	Source	Target
Compression	Lossless	Lossless
Introduced	1999	1989
Browser support	Needs 7-Zip, Keka or similar.	Built into every operating system.

7Z is stronger at: Substantially better compression than ZIP. Strong AES-256 encryption. Open format.
ZIP is stronger at: Built into Windows, macOS and Linux. Individual files can be extracted without unpacking everything. Optional encryption.

Why convert 7Z to ZIP?

People make this switch when they run into the limits of 7Z: sending to someone non-technical. ZIP is the better fit when sending several files to someone whose setup you cannot control.

7Z limitations that prompt the switch: Requires third-party software on both Windows and macOS. Slower to compress. Solid archives make single-file extraction slow.
What you give up: Compresses each file separately, so it is less efficient than solid archives. Its encryption has known weaknesses in the older variant.

What is preserved when converting 7Z to ZIP?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.
