Pics Optimizer — Smart Photo Compression, 100% Offline
Pics Optimizer shrinks your PNG, JPEG and WebP photos using the same color-quantization and dithering techniques professional compression tools use — often 50–70% smaller with no visible loss in quality. Everything runs right here on your device. Nothing is ever uploaded, no account is needed, and it even works with no internet connection at all. ✨ FEATURES • Smart PNG compression — real color-palette quantization with Floyd–Steinberg dithering, not just a basic re-save • JPEG & WebP re-encoding at your chosen quality • 4 quality presets: Lossless, High, Balanced, and Smallest • Convert PNG/JPEG to WebP for extra savings on photos • Batch-process as many photos at once as you like • Before & after comparison slider for every photo • Compression history with total space saved • Light, dark and system themes • Save straight to your gallery or share instantly 🔒 PRIVACY BY DESIGN • No internet permission — the app literally cannot go online • No account, no sign-up, no ads, no trackers • Photos are only read when you pick them yourself • All processing happens locally using your device's own CPU ⚙️ HOW IT WORKS Pics Optimizer looks at each image's colors and picks the best strategy: graphics and screenshots get palette-compressed with dithering to avoid banding, photos are kept pixel-perfect or converted to WebP for the cleanest results, and JPEG/WebP files are re-encoded at your chosen quality. A built-in size guard means you never end up with a bigger file than you started with. 📱 WORKS ON EVERY ANDROID VERSION Pics Optimizer supports Android 7.0 and up, all the way through the latest Android release, with a modern edge-to-edge design on every screen. 📩 CONTACT Questions or feedback?
