How much can PNG files be compressed?

PNG files can typically be reduced by 30-70% depending on the image content. Simple graphics with few colors compress more than photographic images. Our tool uses optimized compression while preserving transparency.

Does compressing PNG remove transparency?

No! Our compression preserves the alpha channel (transparency) in PNG files. The compressed PNG will maintain all transparent areas exactly as the original.

Should I convert PNG to JPG or WebP instead?

If your image doesn't need transparency, converting to JPG can save 70-90% file size. WebP offers even better compression with transparency support. However, if you need lossless quality with transparency, compressed PNG is the right choice.

Why are my PNG files so large?

PNG is a lossless format that preserves every pixel exactly. Screenshots, especially at high resolution, and images with many colors create large PNG files. Compression reduces file size by optimizing the PNG encoding without losing any data.

Can I compress PNG files in batch?

Yes! Upload multiple PNG files at once and compress them all in one click. Each file is processed independently with optimal settings. You can download them individually or all at once.
