CONVERSION GUIDE

HDR to CUR Conversion Guide

HDR to CUR is not available as a browser conversion yet. This guide explains the workflow, what changes in the file, and what must be preserved before upload is enabled.

Guide only. HDR to CUR is not available in the browser yet. This guide explains what must be preserved and links to safer alternatives that work now.

HDR to CUR is not available yet

No upload box is shown until the HDR reader and CUR export path can preserve the file safely.

  • No upload prompt is shown until the conversion is actually supported.
  • Downloads must match the real output format before this page becomes available.
  • No hidden loss of layers, animation, image structure or color data.

What changes before converting HDR to CUR

HDR is a professional or HDR-oriented format where tone mapping and color management are important.

CUR is used for favicons and app icons, so size variants and transparency are important.

HDR input: Radiance HDR images converted to standard formats. HDR conversion needs tone mapping.

CUR output: Windows cursor icon files converted to standard image/icon formats. CUR cursor files are icon-style image containers and need dedicated parsing before upload is enabled.

This page focuses on the exact HDR to CUR task: compatibility, compression, transparency, animation, metadata, color profile and output-quality trade-offs for this pair.

Transparency and layers

  • HDR/pro formats need tone mapping and color profile decisions so the exported image looks correct on standard displays.
  • Metadata, EXIF orientation and color profiles should be handled deliberately rather than silently copied or dropped.

Best use cases for HDR to CUR

  • Make HDR files easier to open in software that expects CUR.
  • Prepare CUR output for upload forms, websites, archives or sharing workflows.
  • Create a predictable CUR copy while keeping the original HDR file untouched.

Quality, file size and compatibility

CUR output should be chosen for the actual destination: web pages need small files, archives need predictable compatibility, design handoff may need transparency, and camera workflows may need color accuracy. ImageConvert separates available routes from guide-only routes so visitors do not get mislabeled downloads or silent animation/layer loss.

For lossy outputs such as JPG, JPEG, JFIF and many WEBP settings, quality can reduce file size but permanently changes pixels. For lossless or alpha-friendly outputs such as PNG and some WEBP settings, transparency and sharp graphics can be preserved when the source data supports it. Professional formats require explicit color management and metadata handling.

What this conversion must preserve

A safe HDR to CUR workflow must decode the source format, preserve the parts users care about, and explain any unavoidable changes before download.

  • File structure, layers, animation, pages or RAW sensor data should not be silently discarded.
  • Transparency, metadata, EXIF orientation and color profiles need explicit handling.
  • The page should offer upload only after downloaded CUR files are verified as real CUR output.

FAQ

Is HDR to CUR available now?

Not yet. ImageConvert explains the workflow and keeps upload disabled until this conversion is reliable.

What changes when I convert HDR to CUR?

HDR/pro formats need tone mapping and color profile decisions so the exported image looks correct on standard displays. Metadata, EXIF orientation and color profiles should be handled deliberately rather than silently copied or dropped.

Will HDR to CUR keep transparency, animation or layers?

It depends on the source and target. CUR output follows CUR format limits, so transparency, animation, editable layers, metadata and color profiles must be handled explicitly by the conversion engine.

Can I keep the original HDR file after converting to CUR?

Yes. ImageConvert is designed to create a new CUR output and leave the original HDR file unchanged.

When this page should become a live converter

This page can become a live converter after ImageConvert has a proven HDR decoder, a real CUR export path, artifact-byte tests and clear limits for file size, metadata and visual fidelity.
