About jpg to png
JPG to PNG converts a JPEG photo into PNG, a lossless format. It is the right tool when you need transparency, when you are working with graphics, screenshots or text, or when you want to archive an image so it cannot degrade further through repeated saves.
PNG stores every pixel exactly, so nothing is lost in the conversion. That is the point: JPEG throws away information permanently every time it is saved, and PNG freezes whatever you have. The consequence is file size. A photograph converted to PNG is typically several times larger than the JPEG it came from, because compressed camera data ends up stored uncompressed.
Practical guidance: use PNG for logos, icons, screenshots, anything with text or hard edges, and anything needing a transparent background. Keep photographs as JPEG, or move them to WebP. The slider here controls how hard the PNG encoder works to squeeze the file without touching a single pixel, which is a completely safe way to trim a few percent with no visual change at all.
Frequently asked questions
Why is my PNG bigger than the JPG it came from?
Because JPEG is a lossy format that discards data to achieve small files, while PNG stores everything. You are getting a bigger file in exchange for no further quality loss, which is a good trade for graphics and a poor one for large photographs.
Does converting JPG to PNG improve the picture quality?
No, and it cannot. The detail JPEG already discarded is gone for good. What PNG does is stop any further loss, so the current state is preserved exactly.
When should I actually use PNG?
For logos, icons, screenshots, diagrams, anything containing text, and anything that needs a transparent background. For ordinary photographs, JPEG or WebP is smaller at the same visible quality.
Can I add a transparent background here?
Not directly, because a JPG contains no transparency to preserve. To get a transparent background you need background removal first, which can then output PNG.
Does the slider reduce quality?
No. It sets how hard the lossless encoder tries to compress. The pixels are identical at every setting, only the file size changes.
Are my files uploaded?
No, all conversion happens in your browser.
