A moderator of this board made some software that can create such transactions (Replace-By-Fee transactions). It's available at this link, but it requires some technical skill to use.
I seriously doubt that OP's transaction is an opt-in RBF transaction, and even if it was he can easily do it through Electrum itself and no need for another tool.
and also achow101 tool is not only for RBF transactions it works for any kind of transaction.
Perhaps I should have written double spend instead of Replace-By-Fee transaction. However I chose to use achow101's terminology because I linked to his software's thread that uses the umbrella term "Replace-By-Fee transaction" to mean both Opt-in RBF and double spend.
My point is his software can create double spend transactions to speed up stuck low fee transactions. He specifically includes electrum in his list of wallets that do not allow you to make double spends (which he terms RBF transactions).
Attempting a Replace-By-Fee (RBF) double spend transactionWhat is an RBF transactionA Replace-By-Fee transaction is a transaction that is nearly identical to your stuck transaction but pays a higher transaction fee.
Since the original transaction most likely does not use Opt-in RBF, the RBF transaction that we will be creating will be considered a double spend and marked as such. The transaction uses Full-RBF and thus may still take a little bit longer to confirm as it is technically a double spend.
How to make an RBF transactionMaking a RBF transaction depends entirely on the wallet that you are using. Some wallet support the advanced functionality required to make an RBF transaction, others do not.
*snip*
Wallets that do not allow you to or ones that I don't know how to make RBF transactionsNot all wallets support the creation of RBF transactions. Many wallets do not allow clearing all unconfirmed transactions to allow for making RBF transactions. The following is a list of wallet software which do not support RBF transactions. If a wallet on this list does support RBF transactions, please let me know and provide instructions for that so I can add it above.
- Blockchain.info and web wallets in general
- Electrum
- Mycelium
- MultiBit Classic
- Bitcoin Wallet for Android
- Breadwallet
- Copay
achow101 is not the moderator of this board. ThomasV (Developer of Electrum and my above comment) is.
My point was achow101 is trustworthy because he is a moderator. Being pedantic he is a moderator of both the Development & Technical Discussion board, and its Alternative clients child board (sub-board), but not this grandchild board (sub-subboard). This link explains the semantics of simplemachines boards.

Using pedantic sematics this board is not a board, it's a grandchild board (sub-subboard).
