Why convert a JPG to PNG?
JPG is the standard format for photos, so it may seem odd to turn one into a PNG. There are good reasons, though:
- A site or app requires PNG. Some upload forms, sticker makers, game mods and print-on-demand services only accept PNG files.
- You are going to edit the image. Every time a JPG is edited and saved again, it is recompressed and loses a bit more quality. A PNG working copy avoids that generation loss.
- You will add text or graphics. Captions, arrows and logos stay razor-sharp in PNG, while JPG blurs the edges around them.
- Next step needs transparency. Tools such as Round Corners produce transparent areas, which only formats like PNG can store.
What this converter does
It decodes your JPG with the browser’s built-in decoder and saves the pixels as a PNG at exactly the same width and height. There are no settings, because PNG has no quality level: what you see in the preview is what you get. holiday.jpg becomes holiday.png, and a batch comes back as a single ZIP.
JPG vs. PNG at a glance
| JPG | PNG | |
|---|---|---|
| Compression | Lossy | Lossless |
| Typical photo size | Small | Several times larger |
| Transparency | No | Yes |
| Sharp text and lines | Slight blur | Perfect |
| Best for | Sharing and storing photos | Editing, graphics, screenshots |
If what you really want is a smaller file, this is the wrong direction: use PNG to JPG or Compress Image. For a modern format that is both small and supports transparency, see JPG to WebP.
Where JPG files come from
Almost every camera and phone saves photos as JPG (iPhones use HEIC by default — see HEIC vs JPG for the difference, and HEIC to PNG to convert those). Images saved from emails, messaging apps and most websites are JPG too. JPG was designed in the early 1990s for photographs, and it is still the most compatible image format in existence, which is why converting away from it only makes sense for a specific reason like the ones above.
Things a format change can’t do
Converting doesn’t add detail, remove JPG artifacts or cut out the background — the PNG keeps the same pixels, including the original white or colored background. It also doesn’t keep the photo’s EXIF metadata: date, camera and GPS location are left out because the PNG is built from pixels only. That makes it a quick way to share a photo without its location; to keep the JPG format and just strip the data, use Remove EXIF Data or read our guide on how to remove EXIF data from photos.
