Free Archive Converter
Convert archives between ZIP, TAR, TAR.GZ and GZIP, bundle loose files into one archive, or open one to pull the files out. It all runs in your browser, so your files never get uploaded. Free, no sign-up, no watermark.
Convert archives in four steps.
Add an archive or some files, pick a format, and download. There is no queue and no upload, because everything happens right on your device.
Add an archive or files
Drop a ZIP, TAR, TAR.GZ or GZIP to convert it, or drop loose files to bundle them into a new archive. Add as many as you like.
See what is inside
Any archive you add is opened on the spot and its files are listed, so you always know exactly what will go into the result.
Choose the output format
Pick ZIP, TAR, TAR.GZ or GZIP. Deflate and gzip compression run natively in your browser, so you can shrink the archive as you convert.
Convert and download
Build the new archive and save it, or pull the files out one by one. It all happens on your device, with nothing uploaded.
What it can read and write.
ZIP, TAR, TAR.GZ and GZIP are fully supported both ways. RAR and 7z need their own software to open, so we list them honestly rather than half-working.
ZIP .zip
The everyday archive, readable everywhere. Read from stored and deflated ZIPs, and write a new one with compression on or off.
TAR .tar
The Unix tape archive. It bundles files without compressing them, so it is usually paired with gzip. Fully read and written here.
TAR.GZ .tar.gz
A TAR wrapped in gzip, the standard on Linux and macOS. Convert a ZIP straight to TAR.GZ, or open one to get the files back.
GZIP .gz
Gzip compresses a single file. Use it for one file on its own. For several files, TAR.GZ is the right choice and the tool will nudge you there.
RAR .rar
A proprietary format that browsers cannot open. To convert a RAR, extract it with its own software first, then bundle the files here.
7-Zip .7z
A powerful format, but it needs a heavy engine to open in a browser. Extract it in 7-Zip first, then archive the files here.
Put the converter to work.
Turn a ZIP into a TAR.GZ
You were sent a ZIP but the server, the pipeline or the person on the other end wants a TAR.GZ. Convert it in one step without touching the command line.
Bundle files to email
Drop a handful of documents and download a single ZIP, so an email or an upload carries one tidy file instead of a dozen loose ones.
Open an archive quickly
No unzip tool handy on a locked-down or borrowed machine? Open the archive here and pull out just the file you need.
Shrink before you upload
Text, code, CSVs and logs compress well. Convert to a deflated ZIP or a TAR.GZ to cut the size before it goes over a slow or capped connection.
Match a required format
A portal only accepts ZIP, or a Linux job only accepts TAR.GZ. Convert to exactly what the other side expects and move on.
Repackage a download
Take the files out of one archive, drop in or remove a few, and build a fresh archive in the format you actually want.
Moving files at scale?
Converting one archive is easy. Packaging exports, wiring up file pipelines, and handling uploads, compression and delivery safely inside your own system is a different job. That is the kind of software we build at Techliphant, shaped around how your business actually runs.
Common questions.
It is a free online tool that changes an archive from one format to another, for example a ZIP into a TAR.GZ, or bundles a set of loose files into a new archive. You add an archive or some files, pick the output format, and download the result. It can also open an archive so you can pull individual files out.
It reads and writes ZIP, TAR, TAR.GZ and GZIP. You can convert freely between them, bundle files into any of them, or extract from any of them. RAR and 7z are not supported, because they are proprietary or need a large engine that browsers cannot run, so extract those with their own software first.
No. This is the key difference from most online archive tools. Every file is read, decompressed and repackaged inside your browser, on your own device. Nothing is uploaded, so it is safe for private, sensitive or commercial files. Because the work runs locally, there is also no queue and no size limit set by us.
Drop the ZIP onto the tool. It opens the ZIP and lists the files inside. Choose TAR.GZ as the output format and press convert, then download the new archive. The whole thing happens on your device in a second or two for a normal-sized archive.
TAR bundles many files into one without compressing them. GZIP compresses a single file but cannot hold more than one. TAR.GZ combines the two: it tars the files together, then gzips the bundle, which is why it is the standard way to share several files compressed on Linux and macOS. This tool builds all three.
Because gzip is a single-file format by design. It compresses one stream and has no concept of multiple files or folders. If you have more than one file and want compression, the tool points you to TAR.GZ instead, which tars everything into one file and then gzips it.
No. Archiving is lossless. The files that come out are byte-for-byte identical to the ones that went in, whichever format you choose. Compression only changes how the bytes are packed for storage, not the file contents, so a document, image or spreadsheet is exactly the same after a round trip.
No. Encrypted archives need the password and the matching cipher to open, and this tool does not handle encryption. If your ZIP is password-protected, unlock it in a desktop tool first, then bring the files here to convert or repackage them.
There is no fixed limit set by the tool. Because everything runs in your browser, the real limit is your device memory, since the files are held in memory while they are converted. Very large archives or a huge number of files can be slow on an older phone, so work in smaller batches if it starts to lag.
Yes. It runs in any modern browser on a phone, tablet or computer, and once the page has loaded it keeps working even without a connection, because there is no server call. There is nothing to install.
Private by design: this converter runs entirely in your browser. Your files are read, decompressed and repackaged on your own device, so nothing is uploaded to a server or stored anywhere. That makes it safe for private, sensitive and confidential files. Because the work happens on your device, very large archives depend on how much memory your device has.
