01 / THE TOOLKIT

Less cleanup.
More listing.

Built around the work sellers actually need to do between scanning a card and adding it to an inventory or selling platform.

⌁

SCAN CLEANUP

Reduce the lines.
Keep the card’s detail.

Adjustable streak cleanup is designed to target scan artifacts while keeping printed artwork and text as intact as possible. Review the preview before exporting.

BATCH EDITING

Work through a stack.

Add multiple images, keep their upload order, tune the result, and export the edited batch together.

02
↗

FLEXIBLE EXPORTS

Ready for your workflow.

Save individual images or collect a batch into a ZIP. Choose an export format that fits your listing process.

03
✳

SELLER BRANDING

Add your finishing touch.

Place a custom text or image banner over a scan or around the card, then adjust size, alignment, type, and color.
