Choosing a format
PNG for anything needing transparency, or sharp text and line art where JPEG's compression would blur edges. JPEG for photos, where a smaller file matters more than perfect pixel-level detail. WebP generally produces smaller files than either at the same visual quality, and is well supported by modern browsers, though occasionally an older tool won't accept it.
Common questions
Which format should I choose?
PNG for anything needing transparency or sharp text/line art. JPEG for photos where small file size matters more than perfect detail. WebP usually beats both at the same visual quality, but occasionally isn't accepted by older software.
Will converting to JPEG lose transparency?
Yes — JPEG has no transparency channel, so any transparent areas are filled with white before conversion. PNG and WebP both preserve transparency.
Does converting reduce quality?
Converting to PNG doesn't lose quality — it's lossless. Converting to JPEG or WebP applies compression at the quality level you choose, which is lossy but adjustable.
