I imported my blockchain.com WIF bitcoin private key to Electrum and the address doesn't match the related bitcoin address with the balance. The address that Electrum returns for the private key does start with a '1' though.

I'm hoping to try @nc50lc advice about using the bitcoin key compression tool. I'll try to do this offline but i don't think i can run it on my work laptop so will have to reconnect my personal laptop to the internet.

Am I just copying in the WIF private key as my input key and this will output a compressed and uncompressed version of the address and private key? And hopefully the uncompressed address matches my one on blockchain.com with the BTC balance? Or is there another step e.g. plug the uncompressed private key back into electrum?

Thanks in advance
