Supported file types
File formats you can attach to a Sparkian chat.
You can attach files to any chat two ways: open the + (Add tools and actions) menu and choose Upload files, or just drag a file from your computer and drop it anywhere in the browser window. Sparkian processes attachments for analysis, data extraction, and visual understanding, depending on the model you’re chatting with.

Token usage from attachments
Attaching files increases the total token count of your prompt — larger or multiple files mean more tokens. If your request goes over the base token allowance, Spark cost multipliers apply. See Sparks (credit system) for more details.
