Compress PNG images by converting to WebP or AVIF
PNG files are lossless, so the fastest way to shrink them is to switch format or reduce the pixel dimensions. Converting a PNG to WebP or AVIF typically saves 80–95% and keeps transparency.
PNG Compressor: 3 simple steps
- 1
Add your PNG files.
- 2
Choose WebP or AVIF for the biggest savings, or PNG with a smaller maximum width.
- 3
Download individually or as a ZIP.
If you must keep a PNG, choose PNG output and lower the maximum width. The result stays lossless but with fewer pixels. Everything runs locally in your browser.
