Reduce PNG image size online
PNG compression is generally lossless: it preserves pixel values rather than lowering a JPG-style quality setting. This means the quality slider does not reduce PNG file size. For a large PNG, reducing dimensions or converting to another format may have a bigger effect.
How to use the png compressor tool
Add your PNG file to the compressor. If the file remains too large, consider a smaller image dimension or an output format such as WebP when transparency and browser support meet your needs.
Frequently asked questions
Why does the quality slider not change PNG size?
PNG encoding in this tool is lossless, so a JPG-style quality value does not apply. File size changes mainly through dimensions or format conversion.
Will converting PNG to JPG keep transparency?
No. JPG does not support transparency. Transparent areas are typically flattened against a background when converted to JPG.
