CK Image & PDF Reducer compresses images and PDFs right on your PC. Drag a file in, pick how you want it shrunk, and export — nothing is sent anywhere.
- Resize by percentage — scale both dimensions down together
- Fix Width / Fix Height — set one dimension, the other auto-scales to preserve aspect ratio
- Compress by Quality — reduce JPEG quality to hit a smaller file size
- Target File Size — tell it a size limit (e.g. "under 200 KB") and it searches for the best quality/resolution that fits
- PDF compression — shrinks PDFs by recompressing embedded images (via Ghostscript, installed separately on first use)
- Batch queue — load and process multiple files in one pass
- Drag & drop — drop files straight onto the window
- Windows right-click menu — optional "Reduce with CK Image & PDF Reducer" entry in Explorer's context menu
- HEIC support — reads iPhone-style HEIC images
