How much is tax free in France?

Could you kindly elaborate on the tax-free threshold in France? I'm particularly interested in understanding the specific amount that individuals are not required to pay taxes on. Could you also explain if there are any conditions or exceptions that might apply to this tax-free limit? Additionally, is this threshold applicable to all types of income, or are there certain types of income that are taxed differently? Finally, does this tax-free amount vary depending on personal factors like income level or residency status? Thank you for your assistance in clarifying this matter.
