How to compress a PNG image

Choose a PNG file using the compressor above and follow the available size or optimization settings. Download the output and compare its size with the original. Inspect the result for changes in transparency, sharp text, fine lines and colors before replacing an existing image on a website.

Understand PNG compression

PNG commonly uses lossless compression, which can preserve pixel values while reducing storage requirements. Some optimization workflows may also reduce colors or dimensions to make files smaller, which can change appearance. A photographic PNG may remain larger than a suitable JPG or WebP image even after optimization.

Choose quality for the intended use

Logos, diagrams and screenshots often benefit from PNG’s support for crisp edges and transparency. Check that semi-transparent borders and shadows still look correct on light and dark backgrounds. If the image is intended for a strict upload limit, verify the file size, dimensions and format requirements separately.

Frequently asked questions

Will compression remove transparency? It should be checked because output methods vary. Why is the file still large? Dimensions, color detail and image complexity affect size. Does PNG compression improve blur? No; it does not restore missing detail.
