Image
JPG to PNG
Save a JPEG as a PNG when you need a lossless file.
How to use it
- Add one or more JPEG files.
- Choose JPG to PNG.
- Download the PNG. Expect it to be larger.
Why the file often grows
JPEG has already thrown detail away. PNG stores what is left without that kind of loss, so the same pixels usually take more bytes. The page shows both sizes and will say there is no saving when the PNG is bigger.
Use this when a form, a printer or an older tool refuses JPEG. It does not recover detail the JPEG never had, and it does not add transparency.
Questions
Will the PNG look sharper?
No. It is the same picture, stored differently.
Is there a quality slider?
No. PNG output here is lossless, so there is nothing for a quality slider to do.
Is the JPEG uploaded?
No.
