PNG vs JPG - When to Use PNG Compression
PNG is best for images with text, logos, screenshots, and graphics that require transparency. Unlike JPG, PNG uses lossless compression - so our tool applies smart re-encoding to reduce file size while preserving pixel-perfect quality.
Frequently Asked Questions
Does PNG compression remove the transparent background?
No. Our tool preserves PNG transparency (alpha channel) throughout compression. Your transparent areas will remain intact.
Why is my PNG still large after compression?
PNG compression has limits because it is lossless. For even smaller files, consider converting to WebP - it offers 30–50% better compression than PNG while keeping transparency.
Is this tool free to use?
Yes, completely free. No watermarks, no file limits, no account required.
