How to use JPG to PNG Converter
- Drop one or more JPG, PNG, or WebP images into the converter.
- Choose the JPG to PNG or PNG to JPG direction tab.
- Download the converted file, or a ZIP when you convert a batch.
How it works
- The browser decodes the source image to Canvas, then re-encodes it in the selected direction.
- PNG-to-JPG flattens transparent pixels onto a white background because JPEG has no alpha channel.
Formats and limits
| Input | JPG, PNG, and browser-decodable images. |
|---|---|
| Output | PNG for JPG-to-PNG mode; JPG for PNG-to-JPG mode; ZIP for batches. |
| Transparency | Preserved when exporting PNG; flattened when exporting JPG. |
| Animation | Animated inputs are reduced to one still frame. |
| Metadata | Canvas export usually strips original metadata. |
| Batch and browser | Batch conversion is local; ZIP creation uses browser memory. |
Real failure cases
- A transparent PNG will lose transparency in JPG output.
- Converting JPG to PNG does not restore lost quality; it only changes the container and encoding.
- Very large batches can run out of memory while building the ZIP.
Example result to verify
| Original | 1200x800 PNG screenshot, 640 KB, with no transparency. |
|---|---|
| Target | PNG to JPG mode for a smaller upload. |
| Output | 1200x800 JPG; final bytes depend on source detail and are reported by the browser download. |
| Verify | Use Image Size Checker to confirm output type is image/jpeg and dimensions stayed 1200x800. |
