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.
