How to Compress PNG Images Online

PNG files are typically larger than JPEG because they use lossless compression. SquishPic intelligently converts PNG images to JPEG or WebP format to achieve real file size reduction while keeping the image looking great.

To compress your PNG, upload the file using the tool above and choose your desired output format. Selecting WebP will give you the smallest possible file size. If you need to keep transparency, select WebP — it supports alpha channels unlike JPEG.

Download the compressed file with one click. Everything happens locally in your browser — nothing is sent to any external server, making the process both fast and completely private.
