BMP to HDR Converter (.bmp to .hdr)

Convert Windows Bitmap Image (.bmp) files to Radiance RGBE High Dynamic Range Image (.hdr) directly on your device. BMP is commonly used for legacy windows applications, embedded hardware displays, cad textures, and uncompressed pixel inspection, while HDR is ideal for 3d rendering environment maps in blender, cinema 4d, unreal engine, and maya. Every conversion runs locally in your browser with zero server uploads.

Frequently Asked Questions

Do my BMP files ever get uploaded anywhere?

Never — 100% of the conversion runs locally inside your own device memory with 0 KB sent over the network.

Will BMP to HDR look or sound worse?

Quick heads-up: BMP keeps see-through backgrounds, whereas HDR doesn't — transparent areas get filled with a clean solid backdrop. You can also tweak output quality in Preferences anytime.

How big of a .bmp file can I convert here?

Encoded via direct pixel-buffer binary serialization in JavaScript with zero quality loss.
