v2026.6.6

Image transformation, compression, and decompression codecs

Imagecodecs is a Python library that provides block-oriented, in-memory buffer transformation, compression, and decompression functions for use in tifffile, liffile, czifile, zarr, and other scientific image input/output packages.

Decode and/or encode functions are implemented for the following codecs, image formats, and data transforms: Zlib (DEFLATE), GZIP, LZMA, ZStandard (ZSTD), Blosc, Brotli, Snappy, BZ2, LZ4, LZ4F, LZ4HC, LZ4H5, LZW, LZO, LZF, LZFSE, LZHAM, PGLZ (PostgreSQL LZ), RCOMP (Rice), HCOMP, PLIO, ZFP, SZ3, Meshopt, Pcodec, SPERR, AEC, SZIP, LERC, EER, ZSTD1 (Zstd with hilo filter), NPY, BCn, DDS, BMP, PNG, APNG, GIF, PCX/DCX, TGA (TARGA), TIFF, WebP, JPEG (2 to 16-bit), Lossless JPEG (LJPEG, LJ92, JPEGLL), JPEG 2000 (JP2, J2K), High-throughput JPEG 2000 (HTJ2K, JPH), JPEG LS, JPEG XL, JPEG XS, JPEG XR (WDP, HD Photo), Ultra HDR (JPEG_R), MOZJPEG, AVIF, HEIF, EXR, WIC (Windows Imaging Component), WavPack, QOI, RGBE (HDR), PixarLog, Jetraw, DICOM RLE, CCITT (RLE, T.4 and T.6), PackBits, Packed Integers (TIFF, MONO p and packed), Delta, XOR Delta, Floating Point Predictor, Bitorder reversal, Byteshuffle, Bitshuffle, Float24 (24-bit floating point), Bfloat16 (brain floating point), Quantize (Scale, BitGroom, BitRound, GranularBR), and CMS (color space transformations). Checksum functions are implemented for CRC-32, Adler-32, Fletcher-32, and Jenkins lookup3.

Changes

• Limit IntEnum parameters to documented values (breaking).
• Optimize lzw_decode and remove buffersize parameter (breaking).
• Fix floatpred_encode for zero-stride data (#138).
• Add ZSTD1 codec with optional hilo byte shuffle and BGR to RGB conversion.
• Add cms_info function.
• Add spng_encode filter parameter.
• Add Zarr 3 compatible PCX and TGA codecs.
• Support Python 3.15.
