JP2 Converter

A JP2 file is an image format based on JPEG 2000, an advanced version of the traditional JPEG standard. It uses wavelet-based compression, which provides better image quality at smaller file sizes compared to JPG. JP2 supports both lossy and lossless compression, as well as transparency, higher bit depth, and progressive loading.

Because of its high quality and efficiency, JP2 is widely used in medical imaging, digital archives, satellite imagery, and professional photography, rather than everyday web images.

What is a JP2 file used for?

JP2 files are commonly used for:

• High-quality image archiving

• Medical and scientific imaging

• Satellite and GIS imagery

• Digital libraries and museums

They are ideal where image detail and accuracy are more important than compatibility.

How to open a JP2 file?

JP2 files can be opened with:

• Adobe Photoshop

• GIMP

• XnView MP

• IrfanView (with plugins)

• ImageMagick

Most default image viewers do not support JP2 natively.

Is JP2 better than JPG?

In terms of quality and compression efficiency, yes.
However, JPG has far wider support, which is why JP2 is less common on websites and social media.
