Convert PNG to HDR
Fast, free, and secure PNG to HDR conversion. No registration required.
Whether you have one png file or fifty, converting them all to hdr takes just seconds with Xonvert's browser-based engine. Your source file uses PNG Image encoding (standard since 1996). The output will use HDR Image encoding (available since 1985). This particular format pair is popular among photographers and designers who need reliable, fast conversion.

Advantages of HDR over PNG
There are strong reasons to convert PNG to HDR:
Industry standard: In many image workflows, HDR Image has become the go-to format, making this conversion a frequent necessity.
API and automation: Many automated workflows and APIs expect HDR Image as input, making this conversion necessary for programmatic processing.
Editing flexibility: HDR Image files can be opened in a wider range of editing software, giving you more options for further modifications.
Collaboration ease: Team members and collaborators are more likely to have software that opens HDR Image natively, reducing compatibility friction.
Smaller file size: Efficient compression in HDR Image often produces significantly smaller files than PNG Image, saving storage space and bandwidth.

PNG to HDR: Quality Comparison
Uses DEFLATE lossless compression algorithm Stores luminance data in RGBE (RGB + exponent) encoding These technical characteristics influence how quality is preserved during conversion. For image-to-image conversions, Xonvert applies format-aware algorithms that respect the unique characteristics of both PNG Image and HDR Image. Converting within the same category means most properties transfer naturally. Pixel dimensions, aspect ratio, and DPI information transfer directly between formats.
Converting between image formats is one of the most common file operations. When moving from PNG Image to HDR Image, key considerations include color depth preservation, transparency support, and compression artifacts. Both formats preserve images losslessly, so this conversion is purely a container change with zero quality impact.
Transparency note: PNG supports transparency, but HDR does not. Transparent areas will be replaced with a solid background color (typically white) during conversion.

PNG to HDR FAQ
Is HDR better than PNG?▼
Neither is universally "better" — they serve different purposes. PNG Image excels at lossless compression preserving every pixel perfectly. HDR Image is stronger in captures extreme brightness ranges for realistic lighting. Choose based on your needs.
How long does PNG to HDR conversion take?▼
Most files convert in under 5 seconds. Larger files may take 10-30 seconds depending on your device's processing speed.
Can I convert PNG to HDR in bulk for free?▼
Yes. Free users can batch-convert multiple files. Simply drag all your PNG files into the converter at once. PRO users get higher batch limits and priority processing.
What's the difference between PNG and HDR?▼
PNG Image is a lossless raster format with full alpha transparency support. HDR Image is radiance hdr format for high dynamic range lighting data. Key difference: PNG Image excels at lossless compression preserving every pixel perfectly, while HDR Image offers captures extreme brightness ranges for realistic lighting.
How does the PNG to HDR conversion work technically?▼
Xonvert uses WebAssembly-compiled libraries to decode your PNG file in-browser, process the image data, and re-encode it as HDR. All processing happens on your device's CPU.
What happens to my files after conversion?▼
Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.
What is PNG format?▼
PNG Image is A lossless raster format with full alpha transparency support. It is primarily used for logos, icons, screenshots, UI elements and any graphics needing transparency. Uses DEFLATE lossless compression algorithm
