Convert image files with our easy-to-use and free tool. Our tool lets you upload a HEIC (High Efficiency Image File Format) file and, from this, create a new image saved in the EXR (OpenEXR) format that you can then download and edit within image file editors or use for high-definition printing applications. Our conversion tool can also batch convert multiple HEIC image files; up to 25 files at a time can be converted.
Along with converting HEIC image files to EXR, our tool allows you to also adjust the image with some simple effects, such as applying a grayscale filter to the image. These additional options are available within the Options tab. Along with grayscale, you can also mirror or flip the image if needed. For single HEIC file uploads, you will also see options to resize and rotate your image.
This option can be used to rotate the image in 90° increments.
When selected, this option will flip the image vertically.
When selected, this option will mirror the image horizontally.
When checked, this will apply a grayscale filter to the image, turning any color image into a grayscale image.
When checked, this will apply a negative filter to the image, inverting all the colors within the image.

The HEIC is a modern image format, with the final specification completed in 2015. The format is a container format, which, while mostly used for storing image data, can actually support video, audio, and text data streams.
HEIC files are binary in nature and offer an alternative to existing digital photo formats such as JPEG features better compression while retaining comparable image quality. In some cases, the file size can be 50% that of the equivalent JPG file.

The EXR file format (OpenEXR) is an open-source and free image file format developed by Industrial Light & Magic in 1999. The format was originally developed to be a multi-channel, high-dynamic range raster image file format, which has evolved to include additional features over the years.
The format stores binary image data that can be either a 32-bit integer, a 16-bit integer, or a 32-bit floating point, which can also be compressed via a lossy or non-lossy compression method. The OpenEXR library is freely available to help developers implement the format in their applications.
First click the "Upload..." button, select your HEIC file to upload. Select any configuration options. When the HEIC to EXR conversion has completed, you can download your EXR file straight away.
We aim to process all HEIC to EXR conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the HEIC file you submit to us. The resulting EXR file, once created is deleted 15 minutes after upload and the download link will expire after this time.
No. All our conversion tools process your HEIC file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted EXR file quickly.
Yes! Our HEIC to EXR tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our HEIC conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes. When you have converted your HEIC to EXR, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
