Superior Compression

JP2 wavelet compression delivers cleaner images than standard JPEG at the same file size — ideal for quality-conscious workflows.

Archival Quality

JPEG 2000 supports lossless compression — preserve your HEIC photos in an archival format without any quality degradation.

Cloud Encoding

JP2 encoding runs on Convertio servers — no JPEG 2000 codecs or plugins needed on your machine.

About formats

HEIC (High Efficiency Image Container) is Apple's branded implementation of the HEIF (High Efficiency Image File Format) standard that uses HEVC (H.265) as its image compression codec. Apple adopted HEIC as the default photo format on iPhones and iPads starting with iOS 11 in September 2017, replacing JPEG for newly captured images. HEIC files store photographs compressed with the intra-frame coding mode of the HEVC video codec, which applies sophisticated prediction, transform, and entropy coding techniques that achieve roughly 50% better compression than JPEG at equivalent visual quality. The ISOBMFF (ISO Base Media File Format) container supports multiple images in a single file, enabling Live Photos (a still plus a short video clip), burst sequences, depth maps from dual-camera systems, and HDR gain maps that allow compatible displays to render extended dynamic range. HEIC also stores alpha channels, auxiliary images for computational photography features (portrait mode depth data, semantic segmentation masks), and comprehensive EXIF/XMP metadata. One advantage is storage efficiency: iPhones shooting HEIC use roughly half the storage of equivalent JPEG captures with no visible quality loss, a significant benefit on devices where storage is finite and photos accumulate rapidly. The format's integration with Apple's ecosystem is another key strength — HEIC files are natively supported across macOS, iOS, iPadOS, and iCloud Photos, and automatic JPEG transcoding during file sharing ensures compatibility when sending photos to non-Apple devices. HEIC can also be opened by Windows 10/11 (with codec), GIMP, ImageMagick, and Adobe Lightroom.
Developer: MPEG / Apple
Initial release: 2015
JP2 (JPEG 2000 Part 1) is an image format based on the JPEG 2000 compression standard, developed by the Joint Photographic Experts Group and published as ISO/IEC 15444-1 in December 2000 as the successor to the original JPEG standard. Unlike JPEG's block-based discrete cosine transform, JPEG 2000 uses discrete wavelet transform (DWT) compression, which eliminates the characteristic 8x8 block artifacts visible in highly compressed JPEG images and instead produces a smooth, gradual quality degradation. The format supports both lossy and lossless compression within the same codestream, along with features absent from original JPEG: 16-bit and higher bit-depth images, arbitrary numbers of color channels, alpha transparency, region-of-interest coding (allocating more bits to important areas), and progressive quality or resolution refinement from a single compressed stream. One advantage is superior image quality at low bit rates — JPEG 2000 produces visibly cleaner images than JPEG at equivalent file sizes, particularly below 0.5 bits per pixel where JPEG exhibits severe blocking. The progressive decoding capability is another strength: a single JP2 file can be decoded at any resolution or quality level without encoding multiple versions, valuable for remote sensing and medical imaging where the same image must serve both thumbnail browsing and full-resolution analysis. JP2 is the mandated format for digital cinema (DCI), the preferred format in geospatial data (GeoJP2), and widely adopted in cultural heritage digitization.

Frequently Asked Questions

Why convert HEIC to JP2?

JP2 uses wavelet compression that outperforms standard JPEG — useful in medical imaging, archival, and workflows requiring superior quality retention.

What programs open JP2?

IrfanView, XnView, GIMP, Photoshop, and medical imaging software. Some browsers support JP2 natively or via plugins.

Is JP2 better than JPEG?

JP2 delivers better quality at equivalent file sizes and supports lossless compression. It is preferred for archival and professional imaging.

Does JP2 support lossless mode?

Yes — JPEG 2000 supports both lossy and lossless compression, making it suitable for archival preservation of your HEIC photos.

Is HEIC to JP2 conversion free?

Standard conversions are free. Premium plans handle higher resolutions and batch processing.
