Two options
1.https://app.sparkreceipt.com/login go here with your mobile browser, log in and do it from here, not optimal for mobile but doable.
2. First upload those to Google Drive or somewhere else, and then download to your laptop and do a mass upload from there.
Can I mass upload receipts that are photos on my phone?
