CategoryImage File
DescriptionJPG is the file format for images made by digital cameras and spread throughout the world wide web. Saving in JPG format an image loses its quality, because of the size compression. But at the end you have a much smaller file easy to archive, send, and publish in the web. These are the cases when an image's size matters more than image's quality. Nonetheless, by using professional software you can select the compression degree and so affect the image's quality.

I had a set of Radiance HDR panoramas for a 360 viewer project and needed tonemapped JPGs for the thumbnail grid — this converter produced clean results across the whole batch.

Needed to share HDR environment maps with a client who couldn't open the format — converting to JPG let them review the lighting reference images without installing any special software.

HDR to JPG Converter — Frequently Asked Questions ▼

What is an HDR file?

HDR (Radiance HDR) is a floating-point image format introduced by Greg Ward in 1985 for the Radiance physically-based renderer. It stores 32 bits per pixel (RGBE) with a dynamic range of up to 76 orders of magnitude — far beyond what a standard JPG can represent.

How do I convert HDR to JPG online?

Upload your .hdr file using the button above. The converter loads the floating-point RGBE pixels, tone-maps them to the standard sRGB 8-bit range (default global Reinhard operator), then encodes the result as a baseline JPG at quality 90.

What is lost when going from HDR to JPG?

JPG is 8 bits per channel with sRGB gamma, so the wide dynamic range of the source is compressed to fit. Highlight detail above middle-grey can clip; shadow detail below mid-tone can crush. The tone-mapping picks a balanced exposure but cannot preserve everything.

Can I batch-convert HDR files?

Online conversion is one file at a time. For batches, use the desktop Total Image Converter ($29.90): TotalImageConverter.exe C:\hdr_files C:\jpg_out -c jpg -log:log.txt converts every HDR in the folder.

What is the maximum file size?

The online converter accepts HDR files up to 50 MB. A typical 4K HDR environment map (4096x2048) is about 50 MB; larger panoramas exceed the limit and need the desktop Total Image Converter, which has no size cap.

Are my uploaded files kept private?

Uploaded files are deleted automatically after you download the result. They are not stored, indexed, or shared. For unreleased renders or commercial assets, run conversion locally with Total Image Converter.

Is the tone-mapping configurable?

Online conversion uses a single fixed tone-mapping curve tuned for natural-looking output. For control over exposure, white point, and operator (Reinhard, Drago, Mantiuk, Fattal), use the desktop Total Image Converter, which exposes these parameters per file.
 

 

Convert HDR to JPG — Tone-Map Radiance High-Dynamic-Range Images

Radiance HDR (.hdr) stores light values that go far beyond what an SDR monitor can display — fine for 3D rendering and IBL workflows, useless for sharing in an email or embedding on a web page. Converting HDR to JPG applies tone mapping and gamma correction to compress the 32-bit-per-channel range into an 8-bit JPG that opens in every viewer, every browser, and every chat client. Drop your .hdr file above.

What Is HDR?

HDR (Radiance High Dynamic Range, also called RGBE) is the floating-point image format developed by Greg Ward in 1986 for the Radiance synthetic imaging system. Each pixel stores red, green, blue, and a shared exponent as 32 bits total, encoding a luminance range of roughly 10⁻⁴ to 10⁴ — about 76 stops of dynamic range, far beyond camera sensors or display panels. HDR is the standard format for image-based lighting (IBL) environment maps in 3D renderers like Blender, V-Ray, Arnold, and Cycles, and for capturing real-world light probes.

What Is JPG?

JPG (JPEG, ISO/IEC 10918) is the universal lossy raster image format, finalised in 1992. Every browser, every smartphone, every email client, and every photo viewer renders JPG natively without any extra software. The format uses 8 bits per channel, supports sRGB by default, and applies DCT-based compression tuned for natural photographs. A typical 12-megapixel JPG occupies 2-5 MB; the same image as uncompressed HDR would run roughly 50 MB. JPG cannot store HDR information directly — tone mapping must be applied during conversion.
