JPG vs PNG vs WebP
| JPG | PNG | WebP | |
|---|---|---|---|
| Compression | Lossy | Lossless | Lossy or lossless |
| Transparency | No | Yes | Yes |
| File size | Small | Large | Smallest |
| Best for | Photos, sharing | Logos, screenshots, text | Websites, apps |
Converting from a lossy format (JPG/WebP) to PNG won't restore lost detail, but it prevents any further quality loss when you edit the image again.
Frequently asked questions
Which format should I use?
JPG for photos (small files, universal support). PNG for screenshots, logos and anything with transparency or sharp text (lossless). WebP for websites — usually 25–35% smaller than JPG at the same quality, and supported by all modern browsers.
What happens to transparency when converting to JPG?
JPG doesn't support transparency, so transparent areas are filled with the background color you choose (white by default). Convert to PNG or WebP to keep transparency.
Can I convert HEIC iPhone photos?
Only in browsers that can open HEIC — currently Safari on Mac and iPhone. On other browsers, set your iPhone camera to "Most Compatible" (JPG) or export the photo as JPG first.
Are my images uploaded?
No. Conversion happens in your browser on your own device.
