Compress PNG Online

PNG files are losslessly encoded, so they tend to be much larger than JPEGs. The fastest way to shrink them is to convert to WebP (lossless or lossy) or reduce resolution. Drop your PNGs below — transparency is fully preserved.

Frequently Asked Questions

PNG uses lossless compression: every pixel is stored exactly. This makes it ideal for screenshots, logos and graphics with sharp edges, but produces much larger files than JPEG for photographs.

No. Transparency (alpha channel) is fully preserved when you output to PNG or WebP. Avoid JPEG output if your PNG has transparent areas — it will fill them with white.

WebP with lossless mode gives smaller files than PNG while keeping full transparency. For photographs accidentally saved as PNG, JPEG is usually 3–5× smaller.

Yes. Convert to WebP (lossless) in the output format selector. Modern browsers support WebP natively, and file sizes are typically 25–35% smaller than equivalent PNG files.
