We present a catalog of near-infrared properties of LEDA galaxies, using the full resolution images from the DENIS survey. The fluxes are integrated in eight homothetic ellipses defined by their proper axis ratio, position angle and major axis (up to twice the blue diameter at the isophote 25mag/arcsec²) extracted from the LEDA database. From the curves of growth in I, J and K_s photometric bands, we estimated different apparent magnitudes and diameters (``total'', ``Kron'' and ``isophotal''). Isophotal parameters refer to the limiting surface brightnesses: 22.5Imag/arcsec², 21.0Jmag/arcsec² and 20.0K_smag/arcsec² for the three photometric bands, respectively. The result is a catalog of 753153 objects (among which there are 508224 galaxies, 34449 probable galaxies and 210480 galaxies to be confirmed). The catalog gives about (the figures vary, depending on the considered magnitude or diameter): 668000 I-band magnitudes, 576000 J-band magnitudes, 357000 K_s-band magnitudes and 452000 I-band diameters, 299000 J-band diameters, 114000 K_s-band diameters. The typical standard deviations for I, J and K_s magnitudes are 0.14, 0.15 and 0.25, respectively, for magnitudes limited at I=16, J=15 and K_s=14. The contamination by superimposed objects probably remains the major source of problems and could require future improvement. The completeness limits in magnitude are about: 15.5, 14.5 and 13 in I, J and K_s, respectively.
