NEW: Native AVIF encoding, Shortcuts.app integration, and Finder Quick Action. The free clipboard image optimizer with zero limits. 100% local, 100% private. ClipSlim is the image and PDF optimizer that lives in your Mac menubar and compresses files the moment you copy them. No apps to open, no menus to dig through. Copy an image or PDF — ClipSlim silently delivers a leaner version, ready to paste. Stop emailing bloated screenshots. Stop waiting for web tools to compress your files. ClipSlim runs entirely on your Mac, processes everything locally, and never sends a single byte to the internet. NEW IN v1.1 AVIF Format Support Native AVIF encoding built right in. Convert any image to AVIF — the next-generation format that delivers smaller files with better quality than JPEG. Before/After Comparison A visual comparison slider lets you see exactly what changed. Drag to compare the original and optimized versions side by side. Selective Metadata Control Keep your copyright intact while stripping GPS coordinates. You decide which metadata stays and which goes. Shortcuts.app Integration The new OptimizeImageIntent works with Apple Shortcuts. Build automation workflows that optimize images as part of your pipeline. Finder Quick Action Right-click any image in Finder and choose Optimize with ClipSlim. No need to open the app or drag files anywhere. Clipboard History Browse your recent optimizations with thumbnail previews. Re-paste any previously optimized image. CORE FEATURES Automatic Clipboard Optimization Every image you copy is compressed in the background. Works with JPEG, PNG, WebP, AVIF, HEIC, TIFF, and BMP. PDF Compression ClipSlim compresses PDF files on your clipboard too. Pages are re-rendered at a target DPI, reducing file size while preserving readability. Folder Watcher Point ClipSlim at any folder and it monitors for new images automatically. Supports conditional folder rules for different optimization settings. Drop Zone Drag and drop images or PDFs directly onto ClipSlim's floating window for instant batch compression. Accepts up to 100 files at once. Smart Format Detection ClipSlim distinguishes screenshots from photos and applies the right compression strategy automatically. Context-Aware App-to-Preset Mapping Assign different optimization presets to different apps. No other image optimizer does this. SSIM Quality Guard Structural similarity analysis ensures compression never degrades your image below an acceptable threshold. Quality Presets Web Quality (75%), High Quality (90%), Compressed (60%), or Custom — set your own quality, max dimension, and output format. Format Support JPEG, PNG, WebP, AVIF, HEIC, TIFF, and BMP. Convert between formats on the fly. Global Hotkeys Option+1: Paste the optimized version. Option+2: Paste the original. Focus Mode ClipSlim skips optimization automatically when you work in specified apps. PRIVACY FIRST ClipSlim processes every file using Apple's built-in ImageIO and Core Graphics frameworks. Nothing leaves your machine. No accounts, no subscriptions, no network calls, no analytics. PERFECT FOR Web developers who need AVIF and WebP assets from their menubar. Designers exporting assets for handoff. Photographers who want selective metadata control. Anyone who has ever pasted a 4MB PNG into a Slack message. REQUIREMENTS macOS 14.0 Sonoma or later SUPPORT Questions or feedback: support@appyaccidents.com
