How it works
- Select or drop one or more PNG files.
- Adjust output quality.
- Convert the batch to JPG.
- Download each result or every image in one ZIP.
Practical example
Select several PNG images and create one JPG version of each while keeping their original dimensions.
Formula and explanation
The browser decodes each PNG file and draws its pixels on a local canvas.
It then encodes the canvas as JPG without sending content to Cifrivo.
JPG uses lossy compression and cannot store transparency, so transparent pixels use the selected background colour.
