PFM to SVGZ Converter
Processing entirely on your device — large files may take a moment.
PFM (Portable Float Map) stores pixels as raw 32-bit floats — the lossless hand-off format for HDR pipelines, radiance research and render passes, riding the same family spirit as PBM/PGM/PPM. Convert SVGZ exactly like SVG — the converter inflates it first — or gzip an SVG back into SVGZ for shipping.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the PFM format
PFM (Portable Float Map) stores pixels as raw 32-bit floating-point values — no palette, no compression tricks, just the numbers. It belongs to the Netpbm family (PBM/PGM/PPM) and is the lingua franca for handing high-dynamic-range data between renderers, tone-mapping experiments and radiance research scripts.
Because the values are floats, a PFM can hold sunlight and candlelight in the same image without clipping. Viewers rarely open it directly: convert to PNG or JPG to get a tone-mapped preview of the same data.
+Strengths
- ✓Full floating-point precision
- ✓Dead-simple text/binary layout
- ✓Widely read by research tooling
!Limitations
- −Enormous files (16 bytes per pixel)
- −Almost no viewer support
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 PFM to SVGZ?
Converting makes sense where the strengths of SVGZ meet what PFM cannot give you. 70-80% smaller than the same SVG Meanwhile Enormous files (16 bytes per pixel) One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this PFM 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 PFM to SVGZ?
No — SVGZ is a lossless format, so every pixel of the converted image matches your original PFM file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several PFM 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.
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.
