SlimShift - PDF Reducer
Compress PDFs – fully offline
Only for Mac
Free
Mac
Shrink large PDFs in seconds and see a live estimate of the final file size before you export. Everything happens locally on your Mac.
SlimShift PDF shrinks PDF files right on your Mac – fast, clear, and without your documents ever leaving your computer.
Job application, scan or presentation: when a PDF is too big for an email attachment or upload form, just enter the size you need. SlimShift PDF shows you how large the file will be before you export – calculated by actually processing your document, not by rough guessing.
HIT YOUR TARGET SIZE
• Enter a target size in MB – on export, resolution and quality are lowered step by step until the file fits
• Set a minimum DPI and JPEG quality so the result stays readable
• Live display of original vs. estimated size, including an estimate of quality loss
COMPRESSION YOUR WAY
• “Images only”: recompresses embedded images – text stays sharp and searchable
• “Whole pages”: saves pages as images for maximum savings, ideal for scans
• Adjust resolution from 72 to 300 DPI and JPEG quality freely
MORE THAN COMPRESSION
• Full color, grayscale, or true black & white (1-bit)
• Remove pages with a click on the thumbnails
• Combine 2 or 4 pages per sheet
• Strip metadata and file attachments
SMART ANALYSIS
Every document is analyzed – pages, images, color, text or scan – and its compression potential is estimated, with recommendations for the right settings.
PRIVATE BY DESIGN
• All processing happens locally on your Mac
• No upload, no account, no tracking
• Works offline
Drop in a PDF, choose your settings, export – done. Your original stays untouched.
