Both PNG and ICO preserve image quality without loss. The conversion between these formats is about choosing the format that best fits your workflow and platform requirements.
PNG (Portable Network Graphics, introduced in 1996) uses DEFLATE (lossless) compression. ICO (Icon File Format, introduced in 1985) uses None (BMP payload) or PNG payload compression. PNG browser support: Universal. ICO browser support: Universal.
Both PNG and ICO use lossless compression. The conversion preserves 100% of the original data — the output file is pixel-for-pixel (or sample-for-sample) identical to the input. No quality is lost during this conversion.
Typical PNG file size: A 12MP photo: ~15-25 MB; a 800x600 screenshot: ~200-500 KB. Typical ICO file size: A multi-size favicon (16+32+48+256): ~15-100 KB.
For the best conversion results, always start from the highest quality source file available. Converting from a previously compressed file compounds any existing compression artifacts. When in doubt, use higher quality settings — you can always re-convert at lower quality later, but you cannot recover quality that has been lost.
