Common issues

Large file size for detailed images

PNG's lossless compression can result in large file sizes for complex images.

  1. Use tools like pngquant to compress the file.
  2. Convert to JPEG or WebP if transparency is not needed.

Transparency issues in some viewers

Some older viewers may not display PNG transparency correctly.

  1. Update the image viewer or use a modern browser.
  2. Convert the image to a supported format if necessary.

Security note

Avoid opening PNG files from untrusted sources.
