PNGJPEGPNG to JPEG Converter
The same conversion as PNG to JPG, written with the longer extension. The useful part is unchanged: a lossless PNG becomes a much smaller lossy file that opens everywhere, on your own machine, a folder at a time.
Drop in your files — Files are written with a .jpeg extension; use the PNG to JPG page for .jpg instead.
Why convert
Why convert PNG to JPEG
For the file size, and because something asked for the .jpeg spelling by name. PNG stores every pixel exactly; JPEG throws away what the eye will not notice and produces a far smaller file. On photographs that trade is almost always worth making.
- An upload form that lists .jpeg and rejects other extensions.
- Getting a large PNG under an attachment limit.
- Older business software that expects the long extension.
- Normalising a mixed folder before a bulk upload.
