When JPG to PNG helps
Each time a JPG is edited and saved again, it is compressed once more and loses a little more detail. PNG is lossless: once a photo is a PNG, cropping, annotating or re-saving it never softens it further. PNG is also what some editors, slide tools and print or sticker services ask for, and the format to start from before you add a transparent background in an image editor.
How to use this page
- Add JPG images by dropping them on the box, pasting them, or with Choose files.
- PNG is preselected under Convert to, so every file is converted straight away.
- Compare the before and after file sizes on each card, then save with Download, or with Download all as one ZIP.
- Select “Try a sample” to watch an example JPG photo become a PNG.
What to expect
- Size: the PNG is almost always larger than the JPG it came from, often by a lot for photos. The result card shows how much larger. That is normal for lossless storage, not a fault.
- Look: the PNG matches the JPG pixel for pixel. Any blockiness already in the JPG stays.
- Background: a JPG is opaque, so the PNG is too. White and Black apply only when saving as JPG, and a PNG keeps any transparency.
- Dimensions: width and height stay exactly as they were.
A WebP, AVIF, GIF or BMP image dropped here is saved as PNG as well, with its transparency kept.
Privacy
Your photos are converted by this browser tab on your own device and are not sent anywhere. The PNG is built from the pixels only, so camera details and any GPS location from the JPG are not copied into it.
Limits
You can add up to 20 images at once, each at most 50 MB and 50 megapixels. HEIC photos from iPhones aren’t supported yet.
