PNG to SVGZ Converter
Processing entirely on your device — large files may take a moment.
PNG is a lossless image format that preserves every pixel exactly and supports transparent backgrounds, which makes it the standard for screenshots, logos and graphics containing text or sharp edges. Convert SVGZ exactly like SVG — the converter inflates it first — or gzip an SVG back into SVGZ for shipping.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the PNG format
PNG was created in 1996 as a free, open replacement for the patent-encumbered GIF, and it has been the reference lossless image format ever since. Pixels are compressed with the DEFLATE algorithm (the same one inside ZIP files), which reproduces the original image exactly — bit-for-bit — while supporting full 8-bit or 16-bit alpha transparency. Screenshots, logos, icons, charts and anything with text or sharp edges should live in PNG.
Because it never discards information, PNG files of photographs are several times larger than JPG — that is the price of perfection. Modern PNG encoders add filters per scanline that make screenshots and flat-color graphics compress surprisingly well. PNG also became the base of APNG, the animation extension that browsers play natively.
+ Strengths
- ✓Truly lossless — every pixel survives exactly as it was
- ✓Full alpha transparency with smooth edges, not 1-bit masks
- ✓Open standard, unpatented, with excellent tooling everywhere
- ✓Ideal for text, line art and flat-color graphics — sharp edges stay sharp
! Limitations
- −Photographs become several times larger than JPG
- −Base format has no animation (that is the APNG extension)
- −16-bit or high-resolution PNGs can grow very heavy
About the SVGZ format
SVGZ is what every SVG is on a well-configured server: the same XML vector content run through gzip. XML compresses spectacularly, so an SVGZ is typically 70-80% smaller than the SVG it came from — which is why Apache and nginx can serve it transparently with a Content-Encoding header.
Converting SVGZ to PNG or JPG simply inflates it first — the vector content is byte-identical to its SVG parent. The other direction (vectorize a raster, then gzip) produces a deploy-ready compressed asset.
+ Strengths
- ✓70-80% smaller than the same SVG
- ✓Transparent to browsers via Content-Encoding
- ✓Full SVG vector fidelity
! Limitations
- −Some tools refuse the double extension
- −Needs gunzip before hand-editing
- −MIME confusion on misconfigured servers
Why convert PNG to SVGZ?
There is a concrete reason this conversion exists: Photographs become several times larger than JPG SVGZ sidesteps that — 70-80% smaller than the same SVG If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this PNG to SVGZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting PNG to SVGZ?
No — SVGZ is a lossless format, so every pixel of the converted image matches your original PNG file. You can also adjust the quality/size balance before converting when the target format supports compression.
Will transparent areas survive the conversion to SVGZ?
Transparency is kept whenever SVGZ actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
Can I convert several PNG files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
