QUICK ANSWER
Is it possible to convert JP2 to PNG?
Yes - JP2 converts to PNG.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

Use the free converter above or open the file in IrfanView (Windows) and save as PNG. If the original JP2 was stored with lossy compression, any artifacts are already baked in - PNG adds no new quality loss but cannot remove existing degradation.

Why convert JP2 to PNG?

JPEG 2000 is rarely supported by browsers or basic image editors, so converting to .PNG makes the image universally viewable without special codecs. PNG is a lossless format, so if the source JP2 was also lossless the conversion is fully pixel-perfect. PNG also preserves alpha transparency, making it the right choice when the JP2 contains a transparent layer.

How to convert JP2 to PNG

macOS - Preview BUILT-IN

Open the .jp2 in Preview, go to File > Export, and choose PNG from the Format dropdown.

Install IrfanView plus its PlugIns pack, open the .jp2, then use File > Save As and choose PNG.

GIMP OPEN-SOURCE

Open the .jp2 via File > Open, then use File > Export As and save with a .png filename.

XnView MP FREE

Open the .jp2 and go to File > Export to save as PNG; use Tools > Batch Convert for multiple files at once.

.JP2 JPEG 2000 Image (ISO/IEC 15444-1)

A JP2 file is a JPEG 2000 image - a wavelet-compressed raster format that supports both lossy and lossless compression. On Windows, open it with the free IrfanView (plus its JPEG 2000…

Quality & what to watch

  • If your JP2 used lossy compression, the artifacts are baked into the source - PNG preserves them exactly but cannot remove them.
  • PNG is lossless, so the output file will often be larger than a lossy .jp2 original.
  • IrfanView on Windows requires the separate PlugIns package from irfanview.com to open .jp2 files; the base installer alone is not enough.

Frequently asked questions

Does converting JP2 to PNG reduce quality?
Not if the original JP2 used lossless compression - PNG is always lossless. If the JP2 was lossy, those artifacts already exist in the source file and PNG adds no new degradation.
Can I batch-convert multiple JP2 files to PNG?
Yes - XnView MP has a built-in batch converter under Tools > Batch Convert. On the command line, ImageMagick handles it with magick mogrify -format png *.jp2.
Will alpha transparency be preserved?
Yes, if the .jp2 contains an alpha channel it carries over to the PNG output, which supports full alpha transparency.
Why can't IrfanView open my JP2 file?
The separate PlugIns package from irfanview.com is required - the JPEG 2000 codec is not included in the base IrfanView installer.
