JP2 to AVIF conversion is the process of transforming images stored in the JPEG 2000 (JP2) format into the AV1 Image File Format (AVIF). This converts a wavelet-compressed, often high-dynamic-range JP2 into a modern, highly efficient AVIF image that typically offers smaller file sizes and better compression while preserving detail and metadata when done correctly.

JP2 files use the image/jp2 MIME type and rely on JPEG 2000 codecs, typically used in medical imaging and digital archives. AVIF files use the image/avif MIME type and encode images using the AV1 codec, designed for efficient compression and quality retention. AVIF supports features like HDR and alpha channels, making it suitable for responsive web images.
The AVIF (.AVIF) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like JP2.
While specific technical details aren't available here, AVIF files generally serve the purpose of storing image effectively within their domain.

JP2 (JPEG 2000) is a legacy image format known for lossless compression but has limited browser support. AVIF is a modern image format based on AV1 codec, offering better compression efficiency and wider adoption across web platforms. While JP2 is used primarily in archival and professional imaging, AVIF is ideal for web optimization and streaming.
Keep original JP2 masters for archival: convert a copy to AVIF for delivery but retain the JP2 if you need original wavelet-preserved data or fidelity for future edits.
Aim for quality 70–90 for AVIF when converting photographic JP2s to balance small size with visual fidelity; use lossless AVIF only when exact pixel preservation is required.
For large batches, convert using a command-line tool or server-side encoder with multi-threading; test one representative file first to set the quality/size trade-off.
Be aware JP2 can store high bit depths (10–16 bit) and some AVIF encoders may downsample to 8 bit unless explicitly set to preserve higher bit depth and HDR metadata.

Optimal file sizes depend on content: photographic images often compress 30–70% smaller in AVIF than JP2 at similar perceived quality; simple graphics may not benefit as much.
