Infinitive in French has the same use as in English.
It is a mode, and it cannot be conjuguated (like in English)
The infinitive are in dictionnaries to define the verbs.
There are three kinds of infinitives in French.
The group will imply a specific method to conjuguate the verb
1st group
Verbs finishing with -er are the equivalent of the regular verbs in English
Ex: aimer (to love)
2nd group
Regular verbs finishing by -ir
ex : finir
3rd group - Irregular verbs
Some verbs finishing with -ir, and every verb not finishing with -er
ex: partir
prendre
paraitre
soumettre
.....
The main difficulty is to distinguish the verbs with -ir.
To do so, we conjuguate the verb at the 1st person plural (We) present tense, if the ending is -issons, the verb is regular. Otherwise, it is irregular.
Ex : finir >>>> Nous finissons so Finir is regular (2nd group)
Partir >>>> Nous partons so Partir is irregular
Conjugation is much harder in French than in English. Notwithstanding the numerous exceptions (some verbs do not exist in some tenses), it nearly the impossible mission, even for a french.
