Convert image files with our easy-to-use and free tool. Our tool lets you upload a EXR (OpenEXR) file and, from this, create a new image saved in the PBM (Portable bitmap) 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 EXR image files; up to 25 files at a time can be converted.
Along with converting EXR image files to PBM, 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 EXR 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 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.

A PBM file is a graphics file used to store black-and-white images in a format suitable for use by applications that do not need full color image capability.
The PBM format can store black and white images in a compact and uncompressed binary format, making it perfect for applications of all types.
First click the "Upload..." button, select your EXR file to upload. Select any configuration options. When the EXR to PBM conversion has completed, you can download your PBM file straight away.
We aim to process all EXR to PBM 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 EXR file you submit to us. The resulting PBM 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 EXR 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 PBM file quickly.
Yes! Our EXR to PBM 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 EXR 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 EXR to PBM, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
