Compress PNG Online Without Losing Transparency

Yes, transparency is perfectly preserved. Our algorithm carefully handles the alpha channel (transparency) throughout the compression process. Your logo, icon, or graphic will keep its transparent background exactly like the original, but weigh up to 70% less.

100% safe and private. Your images never leave your device. All processing happens locally in your browser using WebAssembly technology. We don't upload, store, or have access to any of your images. Your files remain completely private.

PNGs are heavier because they store every pixel with exact precision, including the transparency channel, without removing any data (lossless compression). This makes them perfect for logos, icons, and graphics with crisp text, but results in large files. Our compressor removes redundant colors that the human eye can't perceive, reducing up to 70% of the file size without affecting visual quality or transparency.

We use intelligent compression with color quantization that reduces the color palette without affecting visual appearance. The process automatically optimizes your PNG image by reducing redundant colors while keeping transparency 100% intact. This allows up to 70% size reduction, especially effective for logos, icons, and graphics with solid color areas.

Depending on the image, you can reduce between 40% and 70% of the file size. Logos with solid colors, icons, and graphics with flat areas compress better. Illustrations with many gradients, fine details, or complex effects will have less reduction to preserve visual quality and crisp edges.

PNG is ideal for logos, icons, illustrations, graphics with text, screenshots, and any image requiring transparency or crisp edges. It's not the best choice for photographs (use JPG or WebP for photos). PNG excels with solid colors, defined lines, and transparent areas where you need maximum sharpness.

WebP is the best option for modern websites because it offers up to 30% more compression with the same quality and supports transparency, improving load speed and SEO. However, PNG is needed for universal compatibility in emails, Office documents, and as a fallback. Recommendation: use WebP for your website with compressed PNG as backup; for logos in emails or documents, use optimized PNG.

Quality loss is minimal and imperceptible to the human eye. Our algorithm intelligently reduces redundant colors that don't affect visual appearance. For logos and icons, the difference is practically invisible while achieving up to 70% size reduction. If you need zero absolute loss, adjust the quality level to maximum in the settings.
