Compress PNG Images Online Free
Free online PNG compressor. Shrink PNG file size right in your browser: 100% client-side, your images never leave your device.
Drag & drop images here
Everything happens in your browser: your images are never uploaded anywhere. You can also just paste (Ctrl/Cmd+V) an image or an image URL.
Nothing uploaded
Compression happens in your browser using WebAssembly, so your images never touch a server.
Real quality control
A single slider maps to each codec's real quality setting, not a fake preset.
Batch friendly
Drop in as many images as you like: they're compressed in parallel, not one at a time.
