When you use TinyPNG, your images are uploaded to their servers for processing. While they say files are deleted after a few hours, your images still travel over the internet and exist on third-party servers temporarily.
With CanYouSmoosh, your images never leave your device. All compression happens locally in your browser using WebAssembly. There's nothing to trust because there's nothing to send.
TinyPNG requires uploading images to their servers. CanYouSmoosh processes everything locally - your sensitive product photos, personal images, or confidential documents stay on your device.
TinyPNG speed depends on your internet connection and their server load. CanYouSmoosh compresses instantly because everything happens on your machine - no upload, no download, no waiting.
CanYouSmoosh supports AVIF - the next-generation format that can be 50% smaller than WebP. TinyPNG is limited to PNG, JPEG, and WebP.
TinyPNG limits free users to 20 images/month (then 500 for $25/year). CanYouSmoosh is completely free with no limits - compress thousands of images without paying a cent.
