description The invention discloses a WebP entropy coding method, which comprises the steps of: formulating a combined probability table according to a preset rule; reading n consecutive binary bits from a received binary sequence; finding a combined probability of the n consecutive binary bits in the combined probability table; and determining a corresponding coding algorithm according to the combined probability, and acquiring current intervals according to a preset interval by adopting the coding algorithm. According to the WebP entropy coding method, the combined probability table is formulated according to the preset rule, the n consecutive binary bits are read from the received binary sequence, the corresponding combined probability is found, the corresponding coding algorithm is determined according to the combined probability, and the current intervals corresponding to the n consecutive binary bits are calculated in one step according to the preset interval by adopting the coding algorithm, so that the speed of t
