What Is an Image Compressor?

An image compressor reduces a file's size by applying lossy or lossless compression algorithms. Lossy compression discards some pixel data to achieve smaller sizes; lossless compression reorganises the data more efficiently without any loss.

ToolPop lets you choose the quality level for JPG and WebP compression, showing you the file size reduction before you download.
