OpenAnyFile
Works
Viewing, inspecting and verifying. You get the vector artwork after gzip decompression. File details, exact byte size and the detected signature are always shown.
How to open a .svgz file
If double-clicking a SVGZ file did nothing useful, that is normal: the format is fine, your operating system just has no default application registered for it. This page explains the format and gives you a way to read one immediately.
What is a .svgz file?
Compressed SVG is a vector graphic format developed by W3C, first appearing in 2001. It is normally produced by Inkscape, map tile servers.
A gzip-compressed SVG. Servers must send Content-Encoding: gzip or browsers show markup gibberish instead of the drawing.

Open a .svgz file in your browser
OpenAnyFile routes .svgz to its vector renderer, which decompresses and renders the vector artwork after gzip decompression.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .svgz file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the vector renderer.
- Your SVGZ opens on its own viewer page: the vector artwork after gzip decompression.
- Use fullscreen for a closer look, or download the file back out unchanged. Nothing is transmitted anywhere — the parsing happens in your own browser process.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
Local-only by design, not by promise
Plenty of sites promise they delete your uploads. OpenAnyFile avoids the promise by avoiding the upload. When you drop a .svgz file in, the browser grants the page temporary read access to those bytes and nothing more — the page has no path to send them anywhere. You can verify it in seconds: open DevTools, switch to the network tab, and open a file. The request list stays empty.
Frequently asked questions about SVGZ files
Can I open a .svgz file without installing special software?
Yes. OpenAnyFile's vector renderer runs in your browser, so you can read a SVGZ file with nothing installed. You get the vector artwork after gzip decompression. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a SVGZ file?
Look at the first bytes rather than the extension. A genuine SVGZ begins with 1F 8B. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .svgz by mistake is easy to spot.
Is it safe to open a SVGZ file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .svgz file, exactly?
Compressed SVG — an image/svg+xml format created by W3C since 2001. A gzip-compressed SVG. Servers must send Content-Encoding: gzip or browsers show markup gibberish instead of the drawing.
Does the same viewer handle formats related to SVGZ?
Yes — the same engine also opens .ai, .eps, .ps, so you can compare related files without switching tools.

These open with the same engine, so if you have one of these sitting next to your .svgz file, it will open too:
