The PNG Format: Quality Without Compromise

The Portable Network Graphics (PNG) format was designed as an improved, non-patented successor to the GIF format. Its main feature is lossless compression, meaning no pixel data is discarded during saving, maintaining perfect sharpness for logos, graphics, and screenshots.

OptimizeImg uses advanced algorithms to generate PNG files with full support for alpha channels for complex transparencies. By processing your images locally via WebAssembly, we ensure the rendering is identical to the original, allowing you to change formats with the certainty that your graphics will maintain their professional quality without the files ever leaving your device.

Are your PNG files too large?

If after converting your images to PNG the file size is too big, use our lossless compressor to reduce weight without losing a single pixel of quality.
