How to convert JP2 to PNG
- Add your .JP2 file - drop it in the box above or click to browse.
- Convert it to .PNG in a few seconds.
- Download your new .PNG file.
What to expect
- 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
.jp2original. - IrfanView on Windows requires the separate PlugIns package from irfanview.com to open
.jp2files; 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.
