How to open PNG files
Universal. When a browser or application cannot decode the file directly, convert a copy to JPG for compatibility or PNG when transparency and lossless graphics matter.
When to use PNG
- Logos and UI assets
- Screenshots
- Transparent graphics
Best settings for PNG
- Use PNG for logos, UI screenshots, icons, transparent graphics, and images with sharp edges or readable text.
- Choose PNG when lossless output matters more than the smallest possible file size.
- Convert photographic PNG files to JPG, WebP, or AVIF when upload size or page speed is the priority.
Compatibility checklist
- PNG supports full alpha transparency and is safe for transparent web graphics.
- PNG files can be large for photos because the compression is lossless.
- For icons, start with a square PNG before creating ICO or favicon assets.
Limits to consider
- Photos are often larger than JPG, WebP, or AVIF
- Does not provide a standard quality slider
Convert PNG images
Choose an output based on the destination, not just file size. Conversion runs locally in your browser whenever the required decoder is available.
