Smaller PNG files with transparent backgrounds

Prepare logos, screenshots, and website graphics without converting them to another format. PNG compression reduces the color palette to save space, while retaining transparency and the original pixel dimensions. Check gradients, small text, and brand colors in the result before publishing.

Compress PNG FAQ

How do I reduce PNG file size?

Upload your PNG files, select Compress images, and download the results as PNG. There are no settings to configure on this page.

Will my PNG keep its transparent background?

Yes. PNG output supports transparency, so a transparent background remains transparent. Palette compression can change colors and soft edges, so inspect the result on the backgrounds where you plan to use it.

Can I compress PNG without losing quality?

This page uses palette compression to reduce file size, which can change colors. It does not promise pixel-identical, lossless results. For control over PNG quality and compression level, use the bulk image compressor.

Can I compress multiple PNG files for free?

Yes. The Free plan supports up to 10 images per batch, within the file size and daily limits shown in the upload form. Download completed images individually or together as a ZIP. No sign-up is required and no watermark is added.

Can I compress PNG to 100 KB or 200 KB?

This page does not target an exact file size. Savings depend on the image content and how much it has already been optimized. An already compressed image can become larger. Compare the downloaded result with the original; use the bulk image compressor for quality and resizing controls.
