About PNG compression

PNG is great for screenshots, icons, UI captures and graphics with transparency. It keeps hard edges sharp, but it can become heavy when images are large or contain photo-like detail.

If your PNG is a screenshot or transparent graphic, keeping PNG makes sense. If it is a regular photo, converting or compressing it as JPG or WebP will often create a much smaller file.

Questions

Frequently asked

Are PNG files uploaded?
No. They stay on your device and are processed inside the browser.
Does it keep transparent backgrounds?
Yes. PNG output keeps transparency.
Why did the file not get much smaller?
PNG is already efficient for some graphics. Try resizing, or use WebP/JPG if transparency is not needed.
