The MeerKAT Absorption Line Survey (MALS) has observed 391 telescopepointings at L-band (900 - 1670 MHz) at $\delta\lesssim$ $+20\deg$. We presentradio continuum images and a catalog of 495,325 (240,321) radio sourcesdetected at a signal-to-noise ratio (SNR) $>$5 over an area of 2289 deg$^2$(1132 deg$^2$) at 1006 MHz (1381 MHz). Every MALS pointing contains a centralbright radio source ($S_{1\,\mathrm{GHz}} \gtrsim 0.2$ Jy). The median spatialresolution is $12^{\prime\prime}$ ($8^{\prime\prime}$). The median rms noiseaway from the pointing center is 25 $\mu$Jy beam$^{-1}$ (22 $\mu$Jybeam$^{-1}$) and is within $\sim$ 15% of the achievable theoreticalsensitivity. The flux density scale ratio and astrometric accuracy deduced frommultiply observed sources in MALS are less than 1% (8% scatter) and$1^{\prime\prime}$, respectively. Through comparisons with NVSS and FIRST at1.4 GHz, we establish the catalog's accuracy in the flux density scale andastrometry to be better than 6% (15% scatter) and $0.8^{\prime\prime}$,respectively. The median flux density offset is higher (9%) for an alternatebeam model based on holographic measurements. The MALS radio source counts at1.4 GHz are in agreement with literature. We estimate spectral indices($\alpha$) of a subset of 125,621 sources (SNR$>$8), confirm the flattening ofspectral indices with decreasing flux density and identify 140 ultrasteep-spectrum ($\alpha<-1.3$) sources as prospective high-$z$ radio galaxies($z>2$). We have identified 1308 variable and 122 transient radio sourcescomprising primarily of AGN that demonstrate long-term (26 years) variabilityin their observed flux densities. The MALS catalogs and images are publiclyavailable at https://mals.iucaa.in.
