How to Convert PNG to JP2 (JPEG 2000) on Mac
Add your PNG images
Open UniConverter Image Converter on your Mac and use Add Files to import one or more PNG images into the local conversion queue.
Choose JP2 / JPEG 2000 as the output
Open Convert to and select the JP2/JPEG-2000 image output available in the Mac version. JPEG 2000 supports both lossless and lossy coding. Check the output options available in UniConverter for Mac and review the finished JP2 file before replacing the original PNG.
Choose a save folder and convert
Set the Save to folder and run Convert All. Review the JP2 output in the application that will use it, especially if the source PNG relies on transparency, color information, or exact pixel values.
PNG vs JP2: Lossless Web Raster vs JPEG 2000 Image File

|
|
|---|---|---|
| File Extension | .png | .jp2 |
| Full Name | Portable Network Graphics | JPEG 2000 Part 1 (JP2) file format |
| Compression | PNG uses lossless image compression | JPEG 2000 supports both lossless and lossy coding; the actual output behavior depends on the encoder and settings |
| Image Model | Raster image with grayscale, indexed-color, or truecolor data and optional alpha | JPEG 2000 codestream in the JP2 file format, with metadata such as color-space information |
| Typical Use | Web graphics, screenshots, UI assets, transparent graphics, and general image exchange | Specialized imaging, archival/service-image workflows, and applications that specifically support JPEG 2000 |
| Transparency | PNG supports an alpha channel and transparent indexed-color workflows | JP2 can represent opacity-related information, but application and conversion support varies; verify the converted result |
| UniConverter Platform | PNG is a supported desktop input on Windows and Mac | JP2 output is available in UniConverter for Mac |
| Conversion Result | Keep the PNG when its original lossless pixels or transparency are important | Creates a JPEG 2000/JP2 copy. File size, compression behavior, and transparency handling can vary with the source image and output settings, so review the finished file before delivery. |
Why Use UniConverter for PNG to JP2 Conversion on Mac
JP2 Output on Mac
UniConverter for Mac supports JP2/JPEG 2000 as an image output. Use it when a downstream imaging, archival, or specialized application specifically requires JPEG 2000.
Convert PNG to JPEG 2000 Locally
Use Image Converter on Mac to open local PNG files and export JP2 copies directly to the folder you choose.
Understand the Compression Difference
PNG uses lossless compression, while JPEG 2000 supports both lossless and lossy coding. The final JP2 result depends on the available export settings, so review the converted image before replacing the original PNG.
Batch Queue for Multiple PNG Files
Add multiple PNG images to the Mac Image Converter queue, choose JP2/JPEG-2000 as the output, select the save location, and process the supported files together.
Use JP2 for Compatible Imaging Workflows
JP2 is useful when a downstream imaging, archival, or specialized application specifically requires JPEG 2000. It is not a universal replacement for PNG in ordinary web workflows.
Keep PNG When Exact Web Behavior Matters
PNG has broad web use and well-defined lossless image behavior. Keep the original PNG when transparency, browser delivery, or exact source-pixel preservation is important, and treat JP2 as a derivative copy.
