About PNG

PNG is a lossless format: it keeps every pixel exactly and supports see-through backgrounds. It is good for screenshots, logos, diagrams and pictures with transparent backgrounds.

How much smaller will my PNG get?

PNG is lossless, so the tool keeps every pixel and only stores them more tightly. Expect 5 to 30 percent smaller. For a much smaller file, switch the format to WebP: it can also keep see-through backgrounds.

Also make it smaller in pixels

Use "Resize" to set a width in pixels or a percent. A 4000 pixel wide phone photo shown on a website at 1200 pixels wide becomes about ten times smaller.
