About
DropMachine reduces oversized PDFs and common image files on macOS. It is made by ViSSee for the practical moment when a file is too large for email, upload, storage, or sharing.

DropMachine is for Mac users who handle documents and images that are ready to send, submit, archive, or share, but are blocked by file-size limits. It fits individual, client-service, administrative, support, finance, claims, and document-heavy workflows.
Many file-size problems appear late in a workflow: the scan is finished, the form is signed, the report is ready, or the portal rejects the upload. DropMachine keeps the fix close to Finder and the Dock instead of turning it into a full editing task.
DropMachine is not a full PDF editor, a design suite, a cloud conversion service, or a guarantee that every file will meet every outside size limit. Some already optimized or text-only files may not shrink much.
Mac utility
