FAQ
How can I compress PNG images and reduce file size?
You can shrink PNGs by reducing color precision and removing redundant data. This tool provides a “quality” slider that reduces color precision to make PNG files smaller while keeping PNG output.
What are the characteristics of PNG?
PNG is a lossless format with alpha transparency, great for icons, UI assets, and screenshots with crisp edges.
Why does PNG have a “quality” slider?
PNG is lossless and browser exports usually ignore the quality parameter. This tool simulates “quality” by reducing color precision: lower values look more blocky but are often smaller.
Will my images be uploaded?
No. Conversion happens locally in your browser.
