Images to JP2 Converter
Upgrade your archives. Convert images to the advanced JPEG 2000 (JP2) format for superior compression without data loss.
When standard JPEG isn't good enough, professionals turn to JPEG 2000 (JP2). The Images to JP2 Converter allows you to transform your photos into this advanced format. Unlike standard JPEGs which break images into blocky squares, JP2 uses "wavelet technology" to compress images smoothly. This makes it the go-to choice for medical X-rays, satellite imagery, and digital libraries where quality is critical.
JP2 vs. Standard JPEG: What is the Difference?
It is easy to confuse the two, but they are very different technologies:
Feature Standard JPEG (.jpg) JPEG 2000 (.jp2) Compression Lossy (creates artifacts) Lossless capable Zooming Becomes blocky/pixelated Remains smooth Error Resilience Low High (Good for noisy transmission)Who Needs This Format?
You won't see JP2 on Facebook, but it powers major industries:
- Medical Professionals: Hospitals use JP2 (often inside DICOM files) for MRI and CT scans because it compresses huge files without losing diagnostic details.
- Archivists: Museums and libraries use JP2 to scan historical documents. It keeps the text sharp while keeping the file size manageable for databases.
- Geospatial Mapping: Satellite maps (like Google Earth data) are often stored in JP2 because it handles massive image resolutions efficiently.

Frequently Asked Questions
How do I open a JP2 file?
Standard Windows Photos app often cannot open JP2 natively. You may need to download a free plugin, or use professional software like Adobe Photoshop, GIMP, or IrfanView.
Is JP2 better than PNG?
For photographs, yes. JP2 can compress a photo to be much smaller than a PNG while still being "lossless" (keeping perfect quality). However, PNG is still better for simple web graphics and logos.
Why do web browsers not support JP2?
It is complex to decode. Decoding a JP2 image requires more processing power than a standard JPEG. For the web, speed is everything, so browsers stuck with the simpler JPEG format (and now WebP/AVIF).
Can I convert JP2 back to JPG?
Yes. If you receive a JP2 file and can't open it, simply use our Convert to JPEG tool to make it viewable on any device.
