What DropMachine is
DropMachine is a focused Mac utility by ViSSee for reducing PDF and common image file sizes locally. It is the right category when you need a smaller file, not a full document editor.
Mac PDF and image size reduction
Reduce PDFs and images. Just drop.
DropMachine is a local macOS app for making oversized PDFs, JPGs, PNGs, HEICs, and TIFFs smaller. It is built for the moment a file is ready to send, submit, store, or share, but is blocked by a size limit.
- Local processing
- PDFs plus common images
- Recoverable originals
Local Mac app
Reduce files on macOS without a browser upload.
No cloud step
Core reduction happens locally on your Mac.
Safer replacement
Files are replaced only when the result is smaller.
Paid once
A focused utility, not a subscription workflow.
Global savings estimate
Every smaller file adds up.
Since DropMachine began as Smaller PDF in 2016, each reduced file has helped trim a little weight from email, uploads, backups, sync folders, and long-term storage.

Who this is for
DropMachine is for Mac users handling email attachments, client portals, scanned PDFs, signed forms, claims, reports, screenshots, photos, and archives that become too large at the last step.
When to use it
Use DropMachine when local processing, a short drag-and-drop workflow, supported image formats, and recoverable originals are more important than advanced editing controls.
When not to use it
Use a full PDF editor when you need redaction, page editing, forms, or exact export controls. Use an online compressor when the file is low risk and a browser upload is acceptable.
Workflow
Built for the exact moment a file is too large.
DropMachine keeps the job small: choose the file, drop it, and move on with a reduced copy in place.
Drag from Finder, Mail, or Desktop
Use the file where it already lives. DropMachine accepts PDFs, JPGs, PNGs, HEICs, and TIFFs.
Drop onto DropMachine
Use the Dock icon or the app window. Multiple files can be queued together.
Send the smaller file
DropMachine replaces the original only when the output is smaller and keeps a recoverable original.
Use cases
Different file-size problems, same short fix.
Email attachments
Make PDFs and images small enough to send without opening a heavy editor.
Client portals
Get under upload limits for forms, claims, reports, and intake systems.
Scanned PDFs
Reduce image-heavy scans, signed forms, receipts, and document packets.
Image files
Reduce oversized screenshots, photos, exports, HEICs, PNGs, and TIFFs.
Storage cleanup
Trim large documents and image files before archiving or sharing.
File-size problems
Start from the error message in front of you.
DropMachine helps most when a file is blocking the next step. These guides explain what to try, what to expect, and when a file may already be too optimized to shrink much.
PDF too large for email
Reduce scans, forms, reports, and image-heavy PDFs before attaching them again.
PDF too large to upload
Try a smaller local result before returning to the portal, form, or CMS.
Image too large to upload
Make JPG, PNG, HEIC, and TIFF files easier to submit or share.
Reduce scanned document size
Handle bulky scan packets, receipts, signed forms, and OCR documents.
Product proof
A tiny machine for a very common bottleneck.
DropMachine is not a full PDF editor. That is the point. It gives you the one fast path you need when a file is too large for email, a portal, a CMS, or an archive.

Features
Focused features, explained plainly.
Local processing
Your PDFs and images are reduced on your Mac, without a cloud upload for core processing.
Recoverable originals
DropMachine keeps a temporary original so you can restore or recover when needed.
PDF compression
Designed for the everyday PDFs that cause trouble: scans, forms, reports, and image-heavy packets.
Image reduction
JPG, PNG, HEIC, and TIFF files can be reduced when a quick image cleanup is enough.
Benefits
Less waiting, less doubt, fewer detours.
DropMachine is shaped around practical outcomes: private work, faster sharing, simple decisions, and results that still look right in normal use.
Comparison
When online compressors are more tool than you wanted.
Web tools can be useful. DropMachine is for the moments when you would rather keep the file local, avoid another upload, and make the size smaller from your Mac.
