Why convert PNG to JPG?
Size, mostly. PNG stores every pixel losslessly, which is wonderful for editing and terrible for sharing: a phone screenshot lands at 1–3 MB, and photographic PNGs balloon to 10–30 MB. The same image as a quality-0.92 JPG is typically 5–10× smaller and looks identical at normal viewing sizes — which is why upload forms with size limits, email attachments, and slide decks all prefer JPG.
JPG is also the most universally accepted image format in existence. Whatever ancient system, kiosk, or government portal you're dealing with — it takes JPG.
| PNG | JPG | |
|---|---|---|
| Compression | Lossless | Lossy (0.92 quality here) |
| Transparency | Yes | No — flattened onto white |
| Photo, typical size | 15–30 MB | 2–4 MB |
| Hard edges & text | Perfect | Slight ringing artifacts |
| Accepted by | Everything modern | Everything, period |
What happens to transparency
JPG has no alpha channel, so transparent PNG regions must land on something. This tool composites them onto white — the convention that looks right for documents, logos and screenshots. (Naive converters composite onto black, which is how you get those broken-looking logos.) If you need transparency to survive, convert to WebP instead, which keeps alpha at a fraction of the size.
When NOT to convert PNG to JPG
- Images you'll edit again — keep editing masters lossless; export JPG only at the end.
- Sharp-edged graphics with text — JPG's compression rings around hard edges; screenshots of code or UI stay cleaner as PNG/WebP.
- Anything needing transparency — it will be flattened onto white, permanently.
- Already-small PNG icons — flat-color graphics are PNG's home turf; JPG may even be bigger.
