Convert JP2 to PNG Online
Encoding and decoding are computationally expensive, and browser support is virtually nonexistent. Converting to PNG gives you a key advantage: lossless compression with full alpha-channel transparency — every pixel is preserved exactly. PNG is best for screenshots, logos, ui elements, and any image requiring transparency or pixel-perfect accuracy.
Why Convert JP2 to PNG?
Encoding and decoding are computationally expensive, and browser support is virtually nonexistent — converting to PNG overcomes this by providing lossless compression with full alpha-channel transparency — every pixel is preserved exactly
PNG is the right choice when you need to: exporting app and website screenshots with crisp text and interface elements
Gain broader compatibility — PNG works with Universal — all browsers, image editors, operating systems, and web platforms
Your JP2 files were created for archiving high-resolution satellite and geospatial imagery for gis systems, but now you need a format suited to different workflows

How to Convert JP2 to PNG
Upload your JP2 file
Drag your .jp2 file onto the upload area or click to browse. We accept JP2 files up to 200 MB.
Choose PNG as output format
Select .png (Portable Network Graphics) from the format list. PNG uses lossless compression, so your output quality matches the source.
Convert and download
Click Convert and wait for processing. Your PNG file will be ready to download in seconds. The result is optimized for screenshots, logos, ui elements, and any image requiring transparency or pixel-perfect accuracy.
Frequently Asked Questions
Is the JP2 to PNG conversion lossless?
expand_more
When both formats support lossless data, the conversion preserves all content. Lossless with up to 48-bit true color and 16-bit alpha channel; no generation loss on re-save.
How large will my PNG file be compared to the original JP2?
expand_more
JP2 files are typically 500 KB – 100 MB, while PNG files are typically 10 KB – 25 MB. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted PNG file?
expand_more
PNG is compatible with: Universal — all browsers, image editors, operating systems, and web platforms.
What is the maximum file size I can convert?
expand_more
PureConverter accepts JP2 files up to 200 MB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between JP2 and PNG?
expand_more
JP2 (JPEG 2000) is best for medical imaging, satellite imagery, and digital cinema where progressive decoding and lossless compression are critical. PNG (Portable Network Graphics) is best for screenshots, logos, ui elements, and any image requiring transparency or pixel-perfect accuracy. Key tradeoff: JP2's advantage is wavelet-based compression delivers superior quality at low bitrates and supports lossless, lossy, and progressive decoding in one format, while PNG's advantage is lossless compression with full alpha-channel transparency — every pixel is preserved exactly.
Pro Tips for JP2 to PNG Conversion
PNG preserves full quality, so your output file will be as good as the JP2 source — no need to worry about compression artifacts
If your JP2 file has transparency, make sure PNG supports it — PNG supports transparency
PNG works especially well for: saving digital art and illustrations where every pixel must be preserved
Did you know? PNG was created in 1995 specifically to replace GIF after Unisys began enforcing its LZW patent — the name originally stood for "PNG's Not GIF."
