  A possible violation of the weak gravity conjecture (WGC) by cosmic
censorship is one of the major challenges in the field of general relativity.
However, in this paper, we explore the possibility of reconciling the WGC and
the WCCC by considering Reissner-Nordstr\"om (R-N) black holes embedded in
perfect fluid dark matter (PFDM) in asymptotically flat spacetimes. These two
conjectures are seemingly unrelated, but a recent proposal suggested that they
are connected surprisingly. In particular, We argue a promising class of valid
counterexamples to the WCCC in the four-dimensional Einstein-Maxwell theory,
considering a charged black hole when WGC is present. We demonstrate that by
imposing certain constraints on the parameters of the metric, the WGC and the
WCCC can be compatible. Furthermore, we investigate the properties of the
charged black hole in the presence of PFDM for $Q > M$ and present some
intriguing figures to test the validity of the WGC and the WCCC simultaneously.
When PFDM is absent ($\gamma=0$), the RN black hole either has two event
horizons if $Q^2/M^2\leq 1$ or none if $Q^2/M^2> 1$. The second scenario
results in a naked singularity, which contradicts the WCCC. But when PFDM is
present ($\gamma\neq 0$), the RN black hole has event horizons with regard to Q
and M. This implies that the singularity is always covered, and the WGC and the
WCCC are fulfilled. Furthermore, we demonstrate that there is a critical value
of $\gamma$, called $\gamma_{ext}$, that makes the RN black hole extremal when
$\gamma=\gamma_{ext}$. In this situation, the black hole has an event horizon,
and the WGC and the WCCC are still fulfilled. We infer that PFDM can make the
WGC and the WCCC compatible with the RN black hole and that the WGC and the
WCCC agree with each other when PFDM is present.
