How to convert JPG to PNG
Three steps.
Drop your JPGs in
One or many.
Pick PNG as the output
Settings, Output format, PNG. The conversion is deliberate, exactly as requested.
Hit Squish
PNGs come out under new names next to the originals.
The honest reason to do this
Converting JPG to PNG does not restore any quality lost when the JPG was made; nothing can. What it does is stop the bleeding: if you’re about to edit, crop or re-save a photo repeatedly, working in PNG means no further loss with every step.
It’s also a reasonable choice for small collections you want frozen exactly as they are. Just know the files get bigger, because PNG refuses to throw anything away. For big libraries, staying in JPG saves far more space.
Good to know
- No quality is lost in the conversion itself.
- Files come out larger than the JPGs; that’s the price of keeping everything.
- Runs entirely on your machine.
Questions, answered
Does JPG to PNG improve quality?
No, and any tool claiming otherwise is lying to you. The detail the JPG threw away is gone. PNG just guarantees no further loss from that point on.
Does it upload my photos anywhere?
No. Everything happens on your computer. There is no account, no cloud, no watermark, and it works fine offline.
Does it overwrite my originals?
Never. Finished files are written under new names, so the originals and the results live side by side.
Freeze your files, pixel-perfect.
