PNG files are essential for images that require transparency or pixel-perfect precision — logos, screenshots, UI elements, and graphics with text. The tradeoff is file size: a PNG can be 5-10x larger than a JPEG of the same image.

Pikkx compresses PNG files by optimizing the DEFLATE compression algorithm used internally. For maximum size reduction, consider converting to WebP format, which supports transparency and produces files roughly 26% smaller than PNG.

Even with compression, PNG remains the right choice for images where every pixel matters. For web delivery, the best workflow is: keep PNG originals for editing, and serve compressed PNGs or WebP versions to your users.

Frequently Asked Questions

Can I compress PNG without losing transparency?+
Yes. Pikkx preserves the alpha channel (transparency) when compressing PNG images. Your transparent backgrounds remain intact.
Should I convert my PNGs to WebP instead?+
For web delivery, WebP is usually a better choice — it produces files 26% smaller than PNG with the same quality and transparency support. Use Pikkx's format conversion to try both and compare.
Why are PNG files so large?+
PNG uses lossless compression, which preserves every pixel exactly. This produces larger files than lossy formats like JPEG or WebP. PNG compression works by finding patterns in pixel data, so images with large areas of similar color compress better.
Is this tool really free?+
Yes. Pikkx is free for up to 10 images per batch with no limits on batches. Since all processing happens in your browser, there are no server costs to pass on to you.
