Compress PNG Images Online
PNG is the go-to format for screenshots, logos, and any graphic that needs a transparent background — but because it's lossless, PNG files can end up much larger than a photo saved as JPG or WebP.
QuickPixel's PNG compressor re-encodes the file directly in your browser and, for the biggest savings, lets you target an exact size (100 KB, 500 KB, 1 MB) so the result reliably fits upload limits or page-weight budgets. Transparency is fully preserved throughout.
If your PNG is actually a photo rather than a flat graphic, converting it to JPG or WebP first will usually shrink it far more than PNG compression alone — try the PNG to WebP tool if transparency isn't required.
