Safety notes

  • PNG itself cannot execute code, so the format is low-risk. Watch for disguised executables such as .png.exe.

Common mistakes

  • Saving continuous-tone photos as PNG produces huge files. Use JPEG or WebP for photographs.
  • Exporting a PNG with soft shadows into JPEG will lose the alpha channel, leaving a solid background.

FAQ

How can I compress a PNG without losing transparency?
Tools like pngquant and TinyPNG apply palette quantization — visually near-identical with 40-60% smaller files, alpha channel preserved.
