Expert advice to get the most out of PNG to ICO.
Check Your PNG File First
Before converting, make sure your PNG file opens correctly and isn't corrupted. A damaged source file will produce a poor conversion result.
Batch Convert for Efficiency
If you have multiple PNG files, use the batch upload feature to convert them all at once rather than processing them one by one.
Preserve Original Files
Always keep your original files until you've verified the converted output is correct. Don't delete originals until you're satisfied with the results.
Understand ICO Limitations
