Make a giant BMP small enough to actually use
Photographic bitmaps drop from absurd to ordinary: a 24 MB file becomes a 1 MB JPG that mails and uploads.

Photographic BMPs are the heaviest files people routinely find: scans and captures that weigh twenty times what their content justifies. For photos, JPG at quality 85 is the pragmatic landing spot, cutting the file to a few percent of the original with no change visible at normal size. Graphics with text or flat colour should go to PNG instead, where they compress losslessly. The conversion is local, and a resize option handles the oversized scans.
Questions
Will quality 85 damage my scan?
Visibly, no. For archival masters keep a PNG as well; for sharing and uploading, the JPG is indistinguishable and twenty times lighter.
When should I pick PNG over JPG here?
Whenever the bitmap holds text, diagrams or flat colour. JPG's math smears hard edges that PNG keeps perfect.
Is the scan uploaded for conversion?
No. Your browser does the work.
