Add your 7Z file
Drop one or more .7z files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
7Z to ZIP
Repacking a .7z archive as .zip moves the same files into a container with different compression and compatibility trade-offs. Free, private, and validated — the file never leaves your browser.

Repacking a .7z archive as .zip moves the same files into a container with different compression and compatibility trade-offs. A .7z file is a 7-Zip archive built around the LZMA family of compressors, which routinely beat ZIP's ratios by 30-50% on typical data. It is the open, free-software answer to high-compression archiving.
A .zip file bundles files and folders into a single archive, compressing each entry individually. It is the only compression format that every major operating system can open and create without extra software, which is why .zip remains the default way to send multiple files. For this route the practical draw is opens natively on Windows, macOS, Linux, iOS, and Android and random access: any single entry extracts without decompressing the archive — balanced against weaker ratios than 7z or xz, especially across many small similar files, which is worth knowing before you commit a large batch.
Why convert 7Z to ZIP?
The practical trigger for this conversion is usually a mismatch: with .7z, historically no OS opened it out of the box, so recipients often need 7-Zip or a similar app. Switching to .zip buys you opens natively on Windows, macOS, Linux, iOS, and Android, which is why it is the better fit for emailing or sharing a batch of files as one attachment. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
7Z vs ZIP at a glance
| Aspect | 7-Zip archive (.7z) | ZIP archive (.zip) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | solid compression concatenates files into one stream before compressing, exploiting redundancy between files at the cost of random access | every entry is compressed independently, usually with DEFLATE, so a single file can be extracted without touching the rest |
| Strongest at | backups where every saved gigabyte counts | emailing or sharing a batch of files as one attachment |
| Weak spot | historically no OS opened it out of the box, so recipients often need 7-Zip or a similar app | weaker ratios than 7z or xz, especially across many small similar files |
| Metadata | preserves modification times by default, with creation and access times plus file attributes available as optional flags at creation | stores modification times at DOS 2-second resolution and, through the Unix extra field, permission bits — though Windows-made ZIPs usually omit those bits, a classic cause of scripts arriving non-executable |
Pick ZIP as the output
Select .zip in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if ZIP is selectable, the route is real and validated.
Convert on your device
Press Convert. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid ZIP file. Outputs keep the original filename with the .zip extension.
7Z to ZIP questions, answered
Will converting 7Z to ZIP lose quality?
Since 7z is container-oriented and zip is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .zip itself requires.
Is it private to convert 7Z files here?
Yes — the .7z file is processed inside your browser tab and never uploaded. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser. Close the tab and the file is gone from memory.
Where will the ZIP file work?
File Explorer has handled ZIP since Windows XP, Finder and the GNOME/KDE file managers extract it with a double-click, and iOS and Android manage it through their Files apps. No mainstream platform requires any third-party install for basic ZIP work.
Will the ZIP file be bigger or smaller than my 7Z?
It depends on the content: every entry is compressed independently, usually with DEFLATE, so a single file can be extracted without touching the rest. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my 7Z file?
In .7z, preserves modification times by default, with creation and access times plus file attributes available as optional flags at creation. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
