Convert to PNG
PNG is the right call when you need lossless stills or to preserve a clean graphic.
Method
The source is decoded, drawn at native size, and encoded as PNG. No extra compression pass is applied unless you ask.
FAQ
Will PNG files be larger?
Often yes, especially for photographs. PNG shines for text, icons, and graphics with flat color.
Does this keep transparency?
If the source had transparency and the browser can read it, PNG export keeps the alpha channel.
