PNG to PNG Converter

Re-encode a PNG cleanly, optimize its file structure, and choose whether every pixel must stay exact.

  1. Upload one or more PNG files.
  2. Choose lossless or a palette-reduction mode.
  3. Download the re-encoded PNG files.

PNG to PNG is useful when the format is already correct but the file is not. Re-encoding can remove wasteful export settings, rebuild the compressed image stream and produce a clean standards-compliant copy. Lossless mode keeps the decoded pixels and alpha channel unchanged.

For a larger reduction, Light, Balanced and Strong modes reduce the colour palette while retaining PNG transparency. Use those modes for screenshots, interface graphics, diagrams and logos; inspect gradients carefully before replacing a source file.

What actually changes in PNG to PNG conversion?

The container and filename extension stay PNG. The encoder rewrites the image data using a fresh compression pass. Lossless mode changes the packaging rather than the visible pixels; palette modes can merge similar colours to save substantially more space.

Transparency stays in PNG

Unlike conversion to JPEG, PNG-to-PNG processing can retain the alpha channel. Always check soft shadows, hair, antialiased edges and partly transparent overlays on both light and dark backgrounds when using palette reduction.

Frequently asked questions

Why convert PNG to PNG?
To cleanly re-encode a file, reduce avoidable overhead, or create a smaller palette-based PNG without changing formats.
Is lossless mode pixel-identical?
Yes. It re-packs the file without changing decoded pixel or alpha values.
Will transparency be preserved?
Yes. All PNG output modes retain transparency.
Can I process a batch?
Yes. Multiple results are returned together in one ZIP.
