How to convert OpenEXR to QOI

QOI is selected on this page. Files are processed locally; the page downloads its conversion engine on first use.

  1. Choose a OpenEXR file (.exr) or drag it into the workspace. Add up to 30 images, no larger than 20 MB each.
  2. Leave Convert to set to QOI. The quality slider is disabled for this output.
  3. Select Convert images. Open a preview and check the output dimensions.
  4. Download the .qoi file or use Download all (.zip) for a batch. Open the result in the application you intend to use.

Why won't my OpenEXR file convert?

Check that the file is an actual OpenEXR image rather than a renamed file. Try one smaller image first; the input limit is 40 million pixels and 16,384 pixels per side. Allow the processing engine to load before retrying.

Before converting your OpenEXR file

EXR inputs can carry high-dynamic-range values. This tool has no dedicated exposure or tone-mapping controls; inspect the rendered appearance carefully.

What changes in the QOI output?

QOI is a still-image format. Check decoder support before distributing the file; this conversion is not a benchmark of encoding speed or file size.

Supported features and limits

Still image output. Original dimensions are preserved.

Before you use the result

  • Inspect edges and any transparent areas in the exported image.
  • Compare output dimensions and file size. Changing format does not guarantee a smaller file.
  • Animated or multi-page sources produce one still image here. Renaming the extension does not perform a conversion.

If OpenEXR to QOI Converter does not work as expected

If your OpenEXR file fails, confirm it opens in its original application and is not just a renamed file. Try one smaller image to distinguish a format problem from browser memory limits.

Where your input is processed

The tool processes input in your browser. Loading the page and its processing libraries still needs network access. Site analytics and sharing services are separate from file processing; see the privacy explanation below. Privacy details.

A few things to know.

Which image formats can I convert?

Choose from 23 input formats and 21 output formats. HEIC and HEIF are input-only. Animated and multi-page files become a single still image. SVG input must be self-contained; convert text to paths to preserve lettering. SVG output embeds a PNG bitmap; it does not create editable vector paths. PSD output is flattened.

Will my images lose quality?

PNG uses lossless encoding. JPEG, WebP, AVIF, JPEG XL and JPEG 2000 offer quality controls. GIF reduces colors, PGM is grayscale and PBM is black and white. ICO images are scaled to fit 256 × 256. File sizes may grow or shrink. Metadata, including camera and location information, is not copied.

Are my images uploaded anywhere?

No. Your browser handles every conversion locally. Files are not sent to a server or saved after you leave this page. For browser stability, each image is limited to 20 MB and 40 million pixels.
