The TinyPNG website achieves image compression through the use of smart compression algorithms. These algorithms, based on deep learning and machine learning technologies, can detect and remove unnecessary details and redundant information in images, thereby reducing image file sizes.
TinyPNG's compression algorithm mainly detects unimportant pixels in images and replaces them with simpler representations, thus reducing file size.
TinyPNG supports uploading multiple images at once, processing up to 20 images simultaneously.
