About this conversion
The files inside stay exactly the same; only the container changes, for example so the archive opens without extra software.
Good to know
All files are unpacked and packed again; their contents stay identical byte for byte.
Password-protected archives cannot be converted.
How it works
ZIP, TAR and TAR.GZ are unpacked and packed by compact JavaScript code, so this conversion needs no extra download.
libarchive, compiled to WebAssembly and loaded only when needed, unpacks the archive; it is then packed again in a background thread on your device.
Your browser can
- Built-in image codecs
- Hardware video (WebCodecs)
- Multiple threads
- Create AVIF natively
If something is missing, the conversion takes a little longer but still works.
About ZIP archive
ZIP is the most widely supported archive format; Windows, macOS, Linux and phones open it without extra software.
- Sending several files at once
- Downloads and backups
- Office files and apps are ZIPs inside
About TAR.GZ / TGZ (gzip-compressed TAR)
A tar.gz file is a TAR archive compressed with gzip, the most common archive format on Linux and for software downloads.
- Compresses the whole archive in one stream, often smaller than ZIP
- Standard for Linux, macOS and open-source projects
- Keeps folder structure and long paths

Frequently asked questions
Are my files uploaded to a server?
No. The conversion runs entirely in your browser with local code. Your files never leave your device, and there is no upload.
Is there a file size limit?
There is no limit on our side, but your browser memory is. Images work for very large files; for videos, files above a few hundred megabytes can fail on devices with little memory.
Will the quality suffer?
That depends on the target format and settings. Use the quality option to balance size and detail; lossless targets keep everything the source contained.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox and Safari. Fast hardware paths are used where available, with a compatible fallback otherwise.
