Compress PNG Images

PNG files are essential for images that need transparency, sharp text, logos, and graphics with clean edges. The downside? PNGs can be massive. A simple screenshot might weigh 2-5MB, and a high-resolution graphic with transparency can easily hit 10MB+. These bloated file sizes kill page performance, especially on mobile devices where bandwidth is limited and every kilobyte counts.

Coda One's PNG compressor works directly in your browser to reduce PNG file sizes. Since PNG is a lossless format, the compression approach differs from JPG — you can choose to keep the PNG format (which preserves transparency) or convert to WebP for even smaller files. For the best compression ratio, switch the output to WebP or JPEG if your image doesn't need transparency. The quality slider affects the output when converting to lossy formats.

This tool runs in your browser during compression. Your PNG files are processed locally and are not uploaded to our servers during compression. Whether you're optimizing screenshots for documentation, compressing UI assets for a web app, or reducing the size of graphics for email, the compressor gives you a direct-use workflow. Drop your PNG and compress.
