Use cases
When a file is too large, DropMachine has one job.
From client portals to email attachments, DropMachine is built for the practical moments when a PDF or image needs to get smaller without leaving your Mac.
Email attachments
Make oversized PDFs and images easier to send from Mail, Gmail, Outlook, and support threads.
Client portals
Reduce files before uploading to portals with strict size caps and unclear error messages.
Scanned PDFs
Shrink scans, signed forms, receipt bundles, and OCR packets that became too large.
Image files
Reduce JPG, PNG, HEIC, and TIFF files when a quick shareable version is enough.
Storage cleanup
Trim large documents and images before archiving, syncing, or handing them off.
File-size problem guides
Start from the exact blocker: email limits, upload errors, image size, or scanned documents.
Online alternatives
Compare DropMachine with browser-based compressors when privacy or speed matters.
Start local
Make the file smaller before it blocks the next step.
DropMachine keeps the fix short, private, and Mac-native.
