How to Fill a Crack in Ceramic Tile?

no. the right way is to take up the tiles, fix the problem under the tiles (and there is a cause of the problem), replace with new tiles and regrout.

You have cheap tile with a cheap installation. Nothing is going to improve that or fully repair the problem.

"Chase" the cracks and then fill with epoxy or grout. You can experiment with blends of colored grouts to get somewhat of a match for color. Nobody is going to sell you a color match. But you're always going to see the cracks. Latex paint will fill truly hairline cracks, if you only want cosmetic improvement.

Well there's useless, overbroad and wrong info.

I'd say $TheAbove, or you have old tile. Or some failing underneath it. Or settling of the house. or about a billion other things.

Replacing the tiles is the BEST bet. Doing so after figuring out if the underfloor ahs an issue will avoid repeats.

One thing you might consider is the fill thing, but swap tiles (if you don't have/can't get a replacement).

I had some cracked tiles in a bathroom in the middle. Switched them with tiles that were behind the toilet. It was a rental and the tile was from the 50s and impossible to match. I didn't want to retile.

Thanks for your analysis.

The OP asked for repair techniques. "Replace it" is not an answer to that question.

We once moved into a house that had an almond-colored ceramic tile floor in the kitchen that had several hairline cracks and numerous tiny chips that revealed the color below the surface of the tile. The best solution we found for the cracks was an almond-color elastomer-type caulk forced into the crack, then quickly wiped off the surface of the tile. For all the little dings, we used one or more applications of almond-colored appliance touch-up enamel. These repairs were almost undetectable unless you were very close to the floor. The repairs never needed to be re-done in the seven years we lived there.
