Why this size
Why convert JPG to PNG
PNG is lossless. Once your image is a PNG, editing it, adding text or saving it again never adds new JPG blur, which makes PNG the better format for design work, screenshots and anything you will edit several times.
Converting does not bring back detail the JPG already lost, and it does not make the background transparent: a JPG has no transparency to keep. For a cut-out on a transparent background, use the background remover, which saves a PNG.

FAQ
JPG to PNG: questions
- Does JPG to PNG conversion improve quality?
- No. The PNG looks exactly like the JPG. It only stops further quality loss when you edit and save again.
- Can I make the background transparent?
- Not with a format change, because a JPG has no transparency. Use the background remover: it cuts out the subject and saves a transparent PNG.
- Why is the PNG so much bigger?
- PNG stores every pixel without lossy compression. A photo can grow five to ten times in size; that is normal.
- Is there a file limit?
- Up to 25 MB per image. Add up to 5 files at once, or 50 with a free account.
- Are my files uploaded?
- No. Conversion runs in your browser, so your images never leave your device.

How the tool works
The image is decoded in your browser and saved again in the new format at a high quality setting. PNG and WebP keep transparent areas; JPG and GIF get a white background. A JPEG converted to JPG without a size limit keeps every byte and only changes the file name. Everything happens in your browser; your images are never uploaded.
