- Once all files have been converted, you will be presented with files again. Click on "Preview" to see the new images in browser. If you are happy with it, then click on "Save" to save the converted files to your computer.
- Click on the Dropbox logo () in the EXR file selector button.
- The Dropbox file chooser will appear. You will need to authorise access to ezyZip the first time.
- Once you have selected the EXR file, it will download it to your browser and initiate the conversion.

The file will be stored in /Apps/ezyZip folder.
It depends on the original image. If the original image is large and you are also trying to reduce file size significantly, then invariably the quality will suffer. If you reduce the resolution, then the quality will suffer less. You can use the preview functionality to check the quality of the image before saving it.

Why client-side EXR to PNG image conversion is faster and more private
ezyZip converts EXR to PNG images using a WebAssembly-compiled engine that performs pixel-accurate format conversion. Here is why local image conversion is superior:
- Color Space AccuracyProper color space transformations, alpha channel integrity, and color profile handling are maintained through direct memory operations in the WASM heap. ICC profiles are read from the source format and mapped correctly to the target, preserving color accuracy across the conversion.
- Batch ConversionDedicated Web Workers handle batch conversion with per-image progress tracking. Convert entire folders of images between formats in a single operation, with individual status for each file so you can spot any issues immediately.
- Metadata PreservationEXIF data, GPS coordinates, camera settings, and custom metadata fields are mapped from source to target format with maximum fidelity. Where the target format supports the metadata field, it is preserved exactly.
- Format IntelligenceThe engine understands the capabilities of each image format — transparency, animation, bit depth, compression type — and automatically selects the best encoding parameters. Converting a 32-bit PNG with alpha to JPEG, for example, applies proper alpha compositing against a configurable background color.
