Picking the Right Target Format

• PNG: lossless, keeps transparency, worst for photographs — a photo saved as PNG can be 5–10× the JPG size.
• JPG: lossy, no transparency, the default for photos; re-saving a JPG repeatedly degrades it, so convert from the original.
• WebP: usually 25–35% smaller than JPG at equivalent quality, supports transparency and lossless mode — the safest web default today.
• GIF: only for simple animation; a static image never belongs in GIF — a palette of 256 colors destroys gradients.

JPG, PNG or WebP: Which One to Export

JPG suits photographs: it is small and supported everywhere, but it has no transparency and discards detail every time it is saved. PNG is lossless and handles transparency, which makes it right for logos, screenshots and graphics with sharp edges, at the cost of large files for photos.

WebP covers both cases, with transparency and smaller files than either, and every current browser displays it. Converting a JPG to PNG will not restore lost quality, it only makes the file larger. Convert from the best original you have, and pick the target based on where the file will be used.
