HDR to SVG Converter
Processing entirely on your device — large files may take a moment.
Because only browsers and design tools handle SVG natively, exporting it to PNG or JPG makes the artwork usable in Office documents, photo editors and ordinary apps. If your files are still in HDR format, this page is the shortcut: HDR (Radiance RGBE) stores floating-point high-dynamic-range pixels — the format of lighting data and HDRI environment maps.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How HDR compares to SVG
| HDR | SVG | |
|---|---|---|
| Compression | RGBE (RLE runs) | Lossless (gzip-able text) |
| Transparency | Not supported | Native (it is just geometry) |
| Animation | Not supported | SMIL, CSS, JS |
| Metadata | Radiance comments | Arbitrary XML metadata |
| Best for | Lighting data, environment maps | Icons, logos, charts, illustration |

About the HDR format
HDR (Radiance RGBE) is the veteran high-dynamic-range format of lighting research and 3D rendering: pixels stored as a shared 8-bit exponent plus per-channel mantissas, letting one file hold both a sun and a shadow with no clipping. HDRI environment maps for 3D scenes are almost always HDR files.
Standard image viewers show it badly or not at all, because the values can exceed what a screen can display. Converting HDR to PNG tone-maps the file into an 8-bit preview — good for quick inspection, though the floating-point original remains the render-grade master.
+ Strengths
- ✓True high-dynamic-range values
- ✓The standard of HDRI environment maps
- ✓Compact for its precision
! Limitations
- −Not display-ready — needs tone mapping
- −Viewer support is scarce
About the SVG format
SVG (Scalable Vector Graphics) is the W3C's XML-based vector format. Instead of pixels, it stores shapes — paths, circles, polygons, text — as math, which means an SVG logo is a few kilobytes and stays perfectly sharp from a 16-pixel favicon to a billboard. Browsers render it natively, CSS can restyle it, and it scales with zero quality decisions to make.
It is the wrong tool for photographs — vectorizing a photo produces enormous, slow files. It is also worth remembering that SVG is executable XML: files from untrusted sources can carry scripts, so sites typically sanitize uploads. For icons, logos, charts and flat illustration, nothing else comes close.
+ Strengths
- ✓Infinitely scalable with zero quality loss
- ✓Tiny files for icons and geometric art
- ✓Styleable and animatable with CSS and JavaScript
- ✓Text stays selectable and searchable
! Limitations
- −Unsuitable for photographs — files explode in size
- −Complex hand-drawn illustrations can grow heavy too
- −Untrusted SVG can embed scripts and needs sanitizing
Why convert HDR to SVG?
There is a concrete reason this conversion exists: Not display-ready — needs tone mapping SVG sidesteps that — Infinitely scalable with zero quality loss If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this HDR to SVG 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 HDR to SVG?
No — SVG is a lossless format, so every pixel of the converted image matches your original HDR file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several HDR 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 SVG?
Transparency is kept whenever SVG 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.
