How to increase partition size with downloaded firmware

Installing and Using OpenWrt
1

The openwrt firmware customization service is available on the OpenWrt website, https://firmware-selector.openwrt.org/
I have customized an x86 openwrt firmware here, but the partition size after installation is only 120MB, I hope the partition can be larger, such as 1GB, how can I increase the partition size on this website?

you can't, build your own image, or resize post install.

I recommend Gparted to resize partition: https://gparted.org/download.php

What branch of OpenWrt are you running? If SNAPSHOT, just install owut, set option rootfs_size '1024' in the config and use it for all your upgrades. https://openwrt.org/docs/guide-user/installation/sysupgrade.owut#expanding_root_file_system

First, change the virtual disk file size and then the partition on it.
