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.

⚙️ 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.
