About This Tool
The free TinyPNG alternative — unlimited & private
TinyPNG is great but charges after 20 images/month. Our compressor is completely free with no limits. Every image is compressed directly in your browser — nothing is ever uploaded to a server. Files compress automatically the moment you drop them in.
Beyond quality compression, you can convert any image to WebP for 25–35% smaller files, or set a max width to shrink large photos at the same time. Need more? Resize your images or convert to a different format after compressing.
