About Converting JP2 to PNG
JPEG 2000 is an advanced image format offering both lossy and lossless compression with better quality than classic JPG. It is used in archival, medical imaging and cinema. When you need to move away from JP2, the usual reason is simple: poor browser support.
Converting your JP2 image to PNG solves that. PNG is a lossless raster image format that supports a full alpha-transparency channel. It is the standard choice for screenshots, logos, icons and any graphic with sharp edges or text where quality must be preserved exactly. In practice you gain lossless compression keeps every pixel intact and full alpha transparency. PrivConvert runs the whole JP2-to-PNG conversion in server memory and deletes your file the instant the PNG is ready — nothing is stored, logged or reused.
When this conversion helps
- You need lossless compression keeps every pixel intact
- You need full alpha transparency
- You need universally supported in browsers and editors
- Escaping a proprietary JP2 file for the open PNG standard
- Sharing a JP2 image with someone whose software expects PNG
Tips for best results
- PNG preserves quality exactly, so the conversion from JP2 will not introduce any new compression artifacts.
- For the smallest possible PNG without visible quality loss, start from the highest-quality JP2 you have.
- Files up to 250 MB are supported, and you can batch-convert several JP2 files at once; each is processed privately and deleted immediately.

Private by design, not as an afterthought
Most online converters upload your files to a server, keep them for days, and may mine them for AI training or resale. PrivConvert was built the opposite way — around your privacy.
Runs in any modern browser on Windows, macOS, Linux, Android and iOS — no install, plugin or desktop software needed.
Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.
We never keep a copy. Once your PNG is delivered, both the original and the result are gone — there is nothing left to leak or misuse.
Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.
