Compress PNG to 1MB Online Free
Set a 1024 KB target for your PNG image. Processing happens in your browser; review the output size before downloading.
PNG is lossless, so we reach the target by reducing dimensions. Best for screenshots, logos and graphics. For photos, WebP gives a much smaller file.
About PNG compression
