PNG to JP2 — Lossless Meets Lossless
Both formats are lossless; they serve different worlds. When a publisher, archive or imaging system asks for JPEG 2000 and you hold PNG, this free converter re-encodes your images to .jp2 locally in your browser — pixel for pixel.
Pixel-for-Pixel
Lossless in, lossless out: the JP2 decodes back to exactly the pixels of your PNG (with transparency flattened to white, as archival JP2 workflows expect).
Often Smaller Than PNG
JPEG 2000's wavelet compression frequently beats PNG on photographic content while staying perfectly lossless.
Batch Convert Asset Sets
Drop in a folder of PNGs, convert them together, and download one ZIP of JP2 files — no desktop software or server uploads involved.
