Compress PNG Files to 150KB in 3 Steps

What to Expect When You Compress to 150KB
150KB is the sweet spot for most PNG files — good visual quality with significantly reduced file size. Photos look sharp at web resolution and documents remain fully readable.
At 150KB, most users will not notice quality differences compared to the original. Suitable for screen viewing, standard printing, and professional sharing.
PNG is commonly used for screenshots, logos, icons, and transparency graphics. Typical originals land around 1–10 MB, so compressing to 150KB is most useful when you need to meet a strict upload or performance target.
